In response to a curious viewer in Missouri, Beakman begins his second season with an explanation of how submarines work. Noting that they can be over six hundred feet long, Beakman explains that subs operate by controlling their buoyancy, changing their density by taking on water which allows them to rise and sink in water. After demonstrating the different densities of wood, coins and water, he then goes on to make a simple homemade submarine, using a plastic soda bottle, a balloon, some rubber tubing, straws, tape, coins and rubber bands. In the "Beakman Challenge," Beakman reveals that the ball in the back of the throat is called the uvula, and that the windiest spot on earth is in Antarctica. After challenging Lester to push a skewer through a balloon without breaking it, Beakman shows that, by pushing it through the ends of the balloon, it can be done without causing a puncture. Asked about why people regurgitate, Beakman takes the opportunity to first explain digestion. Then, using a blender for a stomach, he constructs a simple model of the digestive tract to show how food is digested, before demonstrating how, acting in reverse, it can be vomited, too. Finally, Beakman explains that the growling noises made by the stomach, or borborygmi, are caused by liquid food being pushed through the intestines.

Asked how the heart pumps blood through the body, Beakman begins by comparing the human body to an apartment building noting that, like apartments which rely on internal systems for things like air and energy, the body's cells are provided with their air, water and food by blood flowing through a network of arteries, veins and capillaries. With the aid of his x?ray viewing lamp, he then goes on to show how the heart's two upper and two lower chambers work like a pump and circulate blood throughout the body. Explaining that smaller animals require more blood to be pumped through their bodies to keep warm, Beakman notes that, while hummingbird hearts beat over one thousand times per minute, a human heart may beat seventy?two times each minute and a blue whale only twenty?five. In this week's "Beakmania," Beakman reveals that all people have a talent for something; that there are more chickens in the world than people; and that animals identify their babies by smell. In the "Beakman Challenge," Beakman poses as cooking show host Art Burn to demonstrate how to make fake glass that you can eat. Using a combination of water, sugar and corn syrup, he heats the mixture to boiling before placing it in a well oiled pie pan to cool. Then, explaining that the sugar is fused in the same way sand is to create real glass, Beakman removes the fake glass from the pan and takes a bite. In response to a question how helicopters fly, Beakman begins by explaining that their rotor blades are actually wings, not propellers. Upon close examination, he shows that the blade is shaped like the wing of an airplane and that in turning, it creates an imbalance in air pressure which results, in the helicopter's flight. Then, after explaining that a propeller on the tail keeps the aircraft from simply spinning around in a circle, Beakman uses a piece of paper, a paper clip and scissors to construct a simple helicopter.

Asked by a curious viewer about batteries, Beakman begins by describing the two basic parts common to all types of batteries ?? a pair of metal electrodes and a chemical electrolyte. With the aid of Balance Man, he shows how electrolytes create a chemical reaction with the battery's electrodes before being brought back into balance by setting up a loop of electricity. Then, using coils of copper and magnesium as electrodes, Beakman makes some simple batteries to power a clock using common electrolytes such as salt water and lemon juice. In "Beakmania," Beakman reveals that roller skates were invented in 1760 by Belgian inventor Joseph Merlin, that a spotted skunk actually does a handstand when it sprays its enemies, and that it takes seventy?two of the body's muscles in order to speak. Then, after a brief moment of tranquility, construction worker Jack Hammer breaks the silence when he arrives to explain how jack?hammers work. In response to a question about why helium?filled balloons fly, Beakman demonstrates that balloons float if they are less dense than their surrounding environment. After showing how balloons filled with helium rise in air, he calls on the 16th century Frenchmen, Joseph and Etienne Montgolfier, to tell how they made travel by balloon possible. So, using a piece of paper, a thimble, a needle, a pencil and a lamp, the Montgolfier brothers demonstrate the principle behind their own hot air balloon flights.

Asked how underwater tunnels are made, Beakman uses a large aquarium to demonstrate how they can be built at the surface, lowered into the water and buried. After employing a hamster to show that his model actually works, Beakman describes a second method which uses a large machine to dig beneath the seabed, and reports how one such tunnel is being built under the English Channel to connect England and France. For "Beakmania," Beakman reveals the name of the oldest living species on Earth (a type of sea snail), the size of a molecule (very small!), and that "O" is the oldest letter in the alphabet. Then, in "Cooking With Art," host Art Burn uses a mixture of milk, vinegar and baking soda to show how a simple glue can be made at home. Responding to a viewer inquiry about steam trains, Beakman begins by explaining that the first steam engine was constructed almost two thousand years ago by the Greek inventor Hero. However, noting that he was at a loss as to what to do with his invention, Beakman reveals that it then took sixteen hundred years for Hero's idea to be put to use. Finally, after describing how their engines work, Beakman notes that a few steam trains are still in operation, and that the next generation of trains will hover above their tracks on a field of magnetic energy.
Sat, Oct 30, 1993
In response to a Massachusetts viewer's inquiry about bats, Beakman notes they are mammals, not birds, and their wings are actually hands with thin membranes of skin stretched between long fingers. Claiming they sleep upside down because it takes less energy, he goes on to explain that, contrary to popular myth, bats actually have good eyesight. Then, aided by Dr. Patricia Brown, Beakman explains how bats are able to hunt at night using sound to build a picture of their environment, or echolocation. During "Beakmania," Beakman notes that the longest living animal was a one hundred and forty?two-year?old turtle which died in 1918; that the most poisonous snake in the world is an Australian marine cobra; and that intense concentration can require as much energy as physical exercise. In the "Beakman Challenge," Lester is asked to break a ruler without holding onto it and using only a hammer. Although Lester doubts it can be done after trying the feat himself, Beakman shows that a large sheet of newspaper creates enough air resistance with its' surface area to hold the ruler firmly in place as it is being struck by the hammer. Asked how gliders fly without a motor, Beakman notes that they rely on converting potential energy into kinetic energy. After using a bowling ball and a swing to demonstrate these two types of energy, he explains that a tow plane transfers its potential energy to the glider by pulling it high into the air before the downward forces exerted by the Earth's gravity are converted into kinetic energy and forward motion by the glider's wings. Finally, after describing how their pilots use rising columns of hot air to stay aloft, Beakman notes that the highest recorded glider flight was to 49,009 feet ?? 10,000 feet higher than large commercial jetliners.

Questioned as to why the sky is blue, Beakman calls on Roy G. Biv to explain that white light is actually composed of a spectrum of colors which are scattered by gas molecules and other particles in the earth's atmosphere. Because higher frequencies of light (like blue) are scattered more and, thus, are more visible than those at the lower end of the spectrum (like red and orange), Biv points out that the sky appears to be blue. Finally, after explaining that light travelling through more of the atmosphere when the sun is closer to the horizon results in more red and orange frequencies left behind at dawn and dusk, Beakman shows that with a jar or aquarium, some water, a flashlight and some powdered milk, a simple experiment can be set up to demonstrate the scattering of light. During "Beakmania," Beakman reveals the name of the heaviest flying bird (the Kori Bustard), that a person will grow four hundred complete eyelashes in a lifetime, and that double-jointedness is actually a result of very elastic ligaments. Then, after a moment of silent meditation and reflection, Woody Chipper explains how wood chippers work. Asked how cars are made, Beakman conjures up the late Henry Ford to explain how the assembly line and use of interchangeable parts made automobile manufacturing more efficient and less expensive. Then, after a challenge from Lester, Ford shows how these two basic concepts can be employed along with the cast of the show to produce twenty?five identical red wagons in no time at all, while Lester is unable to make even one on his own. Finally, a look at a modern day Ford assembly plant in Dearborn, Michigan, shows how thirty?five cars an hour are turned out twenty?four hours a day.

Asked what doctors are looking for during a checkup, Beakman enlists Liza as a nurse and his brother, Meekman, as the patient for a routine physical examination. Though Meekman is worried about what is to come, the doctor assures him that everything will be fine and proceeds to check his throat, teeth, gums, tongue and tonsils with the aid of a tongue depressor. Then, with an otoscope, the doctor examines Meekman's ears and, using a ophthalmoscope, his eyes and brain. After a look at his nose with a nasal spectrum, the doctor completes Meekman's exam by checking his heartbeat and blood pressure before feeling for any irregularities with his internal organs. After fielding questions about why bulls charge at the color red (They don't! They actually charge at any kind of motion), and the number of varieties of rice (almost fifteen thousand), Beakman invites chef Art Burn for another segment of "Cooking With Art." For a recipe he calls "Egg in a Bottle," Chef Burn uses boiling water to heat the inside of the bottle as he demonstrates how the cooling of the air inside causes a change in air pressure which sucks the egg inside. Responding to a viewer inquiry about oil, Beakman explains it is not made out of the remains of dinosaurs, but plant and animal life which was buried at the bottom of the Earth's oceans millions of years ago. But, when Lester expresses some skepticism that oil can be created from such basic organic matter, Beakman places wood shavings in a flask and, with heat, distills them into a slimy organic liquid and flammable gas.

Asked why the moon is sometimes half and sometimes full, Beakman begins by explaining the Earth's 500 million year old satellite is our closest neighbor, orbiting the planet at 2,300 miles per hour. Noting that the moon doesn't actually shine, but instead reflects the sun's light, Beakman enlists Liza, Lester, and a big spotlight to show how these phases are caused by the Earth's position relative to the moon. Then, asked by Liza why the moon has craters, Beakman uses a flour?filled bathtub and a large rock to demonstrate how impact craters are formed. During "Beakmania," Beakman reveals that penguins do have knees, that hawk's are the creatures with the best vision, and that mother tarantulas kill all but one of their babies. In the "Beakman Challenge," Lester is asked to put out a candle by simply flicking his fingers. But, when his friend is unable to perform the task, Beakman demonstrates how, with the aid of an empty cereal box, he can easily extinguish the flame with a simple flick of his finger. Asked by a viewer about how elevators work, Beakman first explains the principle of the pulley before conjuring up the ghost of Elisha Graves Otis, the man credited with making elevators safe enough for everyday use. Then, using Liza and Lester in a demonstration, Otis constructs a simple elevator before explaining his invention of a brake which keeps an elevator car from falling in case a cable breaks. Finally, Beakman concludes the show with some timely tips on elevator safety.
Sat, Nov 27, 1993
Responding to an inquiry about video games, Beakman notes they are actually computers and goes on to describe their necessary component parts ?? the use of the keyboard, joystick or mouse as an input device; how microprocessors act as their "brains"; how output devices like monitors and printers give information to the user; and why programs are needed to give the game its' operating instructions. Reluctantly agreeing to place himself in a dunk tank, Beakman enlists Lester and Liza to demonstrate how these components act together to make video games work. For "Beakmania," Beakman explains the difference between light and dark meat in poultry (myoglobin in their muscular tissues); that soap was first used for cleaning in 600 B.C.; and that pigs always sleep on their right sides. Then, after a "Beak?Moment" of peaceful tranquility, Beakman and his friends are visited by Cyrus Wren. Explaining how sirens work, Cy demonstrates one which uses a pair of perforated cylinders revolving one inside the other to create their sound. Asked why and how teeth get cavities, Beakman begins with an accounting of the number and types of teeth humans have ?? canines for grabbing, incisors for cutting food, bicuspids for crushing and molars for grinding -- thirty?two in all. Then, with Lester complaining of a toothache, Beakman takes a look inside his mouth and discovers his friend has a cavity. Explaining that cavities are holes left in the tooth after the enamel has been eaten away, Beakman and Liza team up to fill Lester's aching tooth in order to stop the decay and pain.

When a fan asks what makes thunder and lightning, Beakman enlists Liza in a few simple demonstrations to explain static electricity. Revealing that lightning is caused by the neutralization of enormous positive and negative electrical charges between the top and bottom of a cloud, Beakman then uses a metal bowl, polyethylene putty, and a metal can lid to show how lightning can be created at home. Turning to thunder, he notes it is the sound of the shock wave created as lightning heats the air. After "Beakmania" fields questions about fish that live out of water (mudskippers, walking catfish and lungfish), the largest human muscle (the gluteus maximus), and the size of a blue whale's tongue (over twelve thousand pounds!), Beakman turns to his able assistant for the "Liza Challenge." With a penny set atop a plastic ring placed on top of a soft drink bottle, Lester is challenged to make the coin drop into the bottle by hitting the loop. After Beakman's friend sends the penny flying, Liza shows how easy it is by hitting the inside of the ring and pulling the loop out of the way, allowing inertia and gravity to deposit the coin in the bottle with ease. In response to a question about what happens when a bone breaks, Beakman first calls on Liza to give a musical accounting of the bones in the body while Lester sings about their use for support, movement and protection. Noting that bones are light in weight but very strong, Surfer Beakman uses a broken surfboard to demonstrate their three basic steps to healing ?? a hematoma, a fibrous lacing containing osteoblaths and, finally, a callous.

While attempting to answer a question about the size of the universe, Beakman is visited by the famous statesman, inventor and scientist, Benjamin Franklin. Reincarnated as a stand up comic, Franklin gives a historical account of some of his most famous inventions, including the Franklin stove and his kite flying experiment, which proved that lightning is actually electricity. Then, after explaining his invention of the lightning rod, he quickly lists some other accomplishments, including the rocking chair and bifocal glasses. In "Beakmania," Beakman explains why voices sound different when played back on a tape player and the name of the world's smallest tree (a dwarf willow). Moving on to the "Lester Challenge," Lester challenges Liza to accomplish the seemingly impossible task of hammering a nail into a wall using a banana. But, he is astonished when Liza is actually able to do it by freezing the banana first. Asked by a West Virginia fan about chemical reactions, Beakman sets out to describe the four basic types ?? 1) synthesis, when two elements combine to form a new compound; 2) decomposition, the separation of something into its' constituent parts; 3) single displacement, where one element takes the place of another in a compound; and 4) double displacement, where two compounds exchange parts to form new compounds. Finally, after demonstrating these four reactions with the aid of his friends, Beakman closes the show by noting that the human body is the site of millions of chemical reactions each second.
Sat, Feb 26, 1994
Asked for facts about ants, Beakman begins by revealing that not only do they release a chemical to provide a trail for other ants to follow, but that they can also lift fifty times their own weight. After describing the three parts of an ant's body ?? the head, the trunk and the metasoma ?? Beakman takes Lester on a tour of an ant farm for a look at how these insects live. Explaining how their colonies are constructed and describing some human?like behavior exhibited by ants, including the planting and gathering of crops and keeping servants to do their work, Beakman notes that they pose little danger to humans. After revealing the temperature on the planet Pluto (340 to 370 degrees below zero, Fahrenheit), the number of dimples in a golf ball (over 350) and that canned food was first produced in the 1820's, but can openers were not invented until forty years later, Beakman calls on Liza to demonstrate what to do if someone is choking. After warning against trying to remove the obstruction with the fingers, Liza and Lester then demonstrate the Heimlich Maneuver. Asked about collisions, Beakman calls on Professor Boring for a definition before explaining the two types ?? elastic and inelastic. Noting that energy is always conserved in a collision, Beakman adopts the persona of the host of "Wheels of Collisions," a game show in which contestants are challenged to correctly identify examples of these two basic types. Finally, after demonstrating a few collisions, Beakman reluctantly allows himself to be used in an experiment to demonstrate an inelastic collision.

Calling on the Three Stooges to help demonstrate pain, Beakman and Liza explain how 15 million individual nerve cells called neurons produce reactions which transmit messages to and from the brain and all over the body. Then, after Lester painfully demonstrates the small delay between when a message is sent and when it is received, Beakman shows how these pain messages travel along the spinal cord causing reactions known as reflexes. After explaining how pain acts to warn the body, Beakman then shows how swelling is caused by fluids rushing into the injured area and how ice can be used as a healing agent. After revealing that cats see in color while dogs see in only black, white and gray, and the name of the largest fish (the whale shark), Beakman challenges Lester to drink a glass of punch using a pair of straws. Although finding it a simple task, Lester is stumped when Beakman asks that he do it again, this time with only one straw inside the glass. After explaining how the difference between the air pressure inside his mouth and that on the liquid are equalized by the outside straw, Beakman notes that Lester could never accomplish the feat. Dispelling Lester's notion that comets are balls of fire, Beakman calls on nineteenth century astronomy pioneer Maria Mitchell for a detailed explanation. Noting that comets are neither made of fire nor are they "shooting stars", Maria explains that they are actually "dirty snowballs" ?? masses of ice with metal and rock at their centers formed at the beginning of the solar system. Then, after noting that structure of comets ?? the nucleus, the coma and the tail ?? she explains how solar winds form the tail of the comet, which can be either in front or behind the comet, depending on the position of the sun.
Sat, Oct 29, 1994
After receiving a number of inquiries about construction equipment, Beakman takes the opportunity to explain how hydraulics give these machines their strength. Starting with the fact that liquids cannot be compressed or squeezed to make them smaller, he uses a pair of large syringes to demonstrate Pascal's Principle ?? that pressure applied to an enclosed fluid is transmitted to every portion of the walls of its container. Then, using a pair of plexiglass cylinders, he shows how this principle gives Liza a mechanical advantage which allows her to lift Lester with relative ease. Putting it all together, he then shows how construction equipment uses similar cylinders, or hydraulic rams, to lift heavy objects. During "Beakmania," Beakman describes how rattlesnakes get their rattles (by shedding their skin), how much a person can sweat in a day (up to three gallons), and the name of the largest bird that ever lived (the elephant bird). Then, in "Cooking With Art," host Art Burn shows how a mixture of charcoal briquettes, laundry bluing, water, salt and ammonia can be used to grow crystals. After Lester decides to take a stab at answering a question about dinosaurs, Beakman is forced to correct much of his sidekick's woefully out of date information. Saying that while they are reptiles, they are not lizards, Beakman goes on to explain that some dinosaurs may have been warm?blooded, and that they died long before any humans inhabited the Earth. Then, explaining that, contrary to what was once believed, dinosaurs were social animals who traveled and hunted in packs, Beakman concludes by revealing that the biggest dinosaur, called the Seismosaurus, was one hundred and forty feet long.
Sat, Dec 3, 1994
Asked how to make an electric motor, Beakman begins by explaining that they are devices which change electrical energy into mechanical power in order to do work. Then, after describing how they employ one magnet pushing and pulling on another magnet, Beakman shows how a "D" cell battery, a refrigerator magnet, some wire, a pair of large paper clips and an empty toilet paper tube can be assembled into a simple electric motor. After demonstrating that his homemade device does, in fact, work, Beakman notes that similar devices are used in electric trains and fans. During "Beakmania," Beakman reveals that, in addition to good acoustics, people sing in the shower because of the cheerfulness caused by negative ions created by falling water; that there has yet to be a recorded death of a human by a wolf in the United States; and that there are over sixty trillion cells in the human body. Then, in an episode of "Those Disgusting Animals," Beakman and his colleagues reveal all anyone ever wanted to know about lice and how to get rid of them. When a viewer inquires about how clocks tell time, Beakman begins by giving a brief history, beginning with the ancient Babylonians and their sundials, through the Egyptian water clock and the hourglass. Then, as the inventor of the pendulum clock, Christian Huyghens, Beakman describes how he built on Galileo's work with pendulums to create a timepiece that was far more accurate than any of its predecessors. After explaining that most watches now use vibrating quartz crystals instead of pendulums, Beakman concludes by revealing that the atomic clock uses Cesium combined with a quartz crystal to measure time in the billionths of a second.

Asked about the difference between frogs and toads, Beakman explains that these two amphibians are hatched as small aquatic larvae called tadpoles. Noting that they undergo a change into air?breathing animals, Beakman uses time lapse photography to show this amazing metamorphosis. Then, after explaining how both hunt using long, sticky tongues, Beakman explains that while frogs live in or near water, toads are mostly land dwellers. Finally, Beakman dispels the myth about frogs and warts as he presents the world's largest frog ?? the Goliath frog from West?Central Africa. For "Beakmania," Beakman notes that eyelashes are to keep dirt out of the eyes, that a young kangaroo is called a joey, and that a certain species of sponge can be broken into thousands of tiny pieces before reassembling itself into a single, living creature. Then, Liza presents a health tip on how to stop a nosebleed. Responding to an inquiry about plastics, Beakman reveals they are really long, chain?like strings of molecules called polymers. Using individual molecules, or monomers, Beakman goes on to show how they can be bonded together in these long chains. Showing how polymers have a variety of uses and properties, he demonstrates how to make nylon and bakelite before showing how a simple polymer can be made at home using borax, glue and water.
Sat, Nov 12, 1994
Asked by an Ohio fan about money, Beakman calls on Dap, the Chap from Yap, whose island's residents use large stones for currency. After Dap explains how the idea for money grew out of difficulties with a simple barter system, Beakman notes that the U.S. Mint produces fifteen billion coins each year, while the Bureau of Printing and Engraving prints an average of twenty?three million paper bills every day. Then, demonstrating how counterfeiting is made difficult, Beakman shows how bills are given distinctive, difficult?to?copy markings. For "Beakmania," Beakman takes on questions about dandruff (flakes of dead skin) and the world's fastest animal (a bird called the swift). Then, in the "Beakman Challenge," Lester is asked to place a ping pong ball into a jar without touching the ball itself. When he is unable to satisfy the request, Beakman places the jar over the ball and then swirls it in tight circles to produce centripetal forces on the ball which cause it to climb the walls of the jar. Asked how water produces energy, Beakman explains that its' energy can be changed into electricity by the use of hydroelectric dams. After Liza recaps the differences between potential and kinetic energy, Beakman shows how turbines are used to convert the moving energy of water into mechanical energy which is then transformed into electricity by a generator. Finally, after a demonstration of how moving water can be used to illuminate a small electric light, Beakman reveals that the world's largest dam is under construction in Argentina.
Sat, Nov 26, 1994
Asked about garbage, Beakman begins by noting that Americans throw away about almost half a million tons of trash each day, including, forty?eight million disposable diapers, twenty thousand TV's and forty?three thousand tons of food. Explaining that garbage generally ends up in landfill or being incinerated, Beakman encourages everyone to "reduce" (use less of anything when possible), "reuse" (use, things more than once when you can) and "recycle" (return materials that can be reclaimed). However, as Beakman notes, hazardous materials such as car batteries need to be disposed of with care. After stating that the Earth weighs six quintillion tons, that the largest beaver dams are over 200 feet long, and that the first bus was invented in England back in 1830, Beakman asks for a quiet moment. However, the noisy din of a lawn mower soon shatters his tranquility. Asked by Liza, how it works, owner and operator Lon Mower explains that his grass cutting machine uses a gas?powered internal combustion engine to help turn a cleverly designed blade. Asked how weather is predicted, Beakman first defines meteorology ?? the study of the Earth's atmosphere and the changes in its conditions which produce weather. After discussing the value of knowing what the weather will be, Beakman relates the history of instruments like the thermometer and barometer before revealing that more than 3,500 stations around the world are used in conjunction with satellites to help forecasters with their predictions. Finally, after Beakman makes a simple barometer from some common household items, he notes that the hottest recorded temperature was 136 degrees Fahrenheit (in Libya), while the coldest was 128 below zero (in Antarctica).
Sat, Nov 19, 1994
Responding to an inquiry about skyscrapers, Beakman explains that the first of these tall buildings was constructed in Chicago in 1855. Then, after recounting a history which took them from a modest ten stories to a dizzying 102 in less than fifty years, Beakman reveals the engineering secrets behind their success, including deep foundations and steel skeletons. Finally, Beakman notes that the world's tallest building, the Sears Tower in Chicago, stands 110 stories (1,454 feet) tall. While Beakman reveals that crabs have the ability to grow a new leg after losing one, Lester takes control of the show as he and his pet chicken introduce the "Scratchy Challenge." But, after Lester fails at lifting an ice cube from a glass using a piece of string, Scratchy shows salt can be used to lower the water's freezing point, allowing the ice to freeze around the string and be removed with ease. Responding to a viewer's complaint about not having a chemistry set, Beakman reveals that many common household items can be used to make one at home. Demonstrating by an experiment that distinguishes acids from bases, Beakman makes a simple indicator out of red cabbage and water to test some common acids (vinegar, grapefruit juice, lemon?lime soda and vitamin C) and bases (ammonia, antacid, milk and baking soda). Finally, Beakman concludes the show by demonstrating the volcanic reaction between vinegar and baking soda.
Sat, Nov 5, 1994
Asked about sharks, Beakman notes that among the 350 different kinds, the smallest is the Spined Pygmy shark at just ten inches long, while the largest in the forty foot, 32,000 pound Whale shark. While claiming that few are a threat to humans, Beakman reveals that the Great White shark is the most dangerous of all, that sharks wear their teeth out and quickly grow replacements, and that they must always stay in motion to keep their blood circulating. Then, after Beakman presents a live Leopard shark to his friends, he explains that sharks are so sensitive as to be able to detect minute electrical emissions which help them track their prey. During "Beakmania," Beakman reveals that the human body can go two months without food but only four minutes without oxygen, that it takes 720 peanuts to make a pound of peanut butter, and that female African elephants have tusks. Then, with help from host Art Burn, "Cooking With Art" demonstrates how soaking an egg in vinegar will make it bounce. Responding to an inquiry about his famous Special Theory of Relativity, Beakman adopts the persona of physicist Albert Einstein. Beginning with a definition of the famous equation E = mc2, Einstein notes that "E" stands for energy, while "m" is an object's mass and "c" is the speed of light. Then, using a series of examples, he explains that matter can be converted into energy, and demonstrates that all objects in the universe move relative to one another.
Sat, Apr 16, 1994
Asked how molds form on bread, Beakman begins by explaining that they are fungi, a family of plant?like organisms that lack chlorophyll. Listing their four types ?- mushrooms, mildews, molds and yeasts ?? Beakman and Liza describe the tube?like structures (hyphae) which weave together into larger webs (mycelium). Then, noting how their lack of mobility requires them to live on their food (like bread), Liza reveals that molds like penicillin save millions of lives each year by eating harmful bacteria, while Beakman claims that the world's largest living organism is a 1,500 acre giant fungus growing underground in the State of Washington. During "Beakmania," Beakman reveals why crabs walk sideways and that part of Canada is actually south of Michigan before introducing "Those Disgusting Animals" look at slugs. Claiming there are over 80,00 varieties of slugs worldwide, Beakman notes that these slimy creatures have two pairs of tentacles, one of which has a pair of eyes at the end. Finally, after describing how they move using a large muscular organ known as a foot,Beakman says that slugs are helpful in cleaning up the environment by eating dead plants and animals. Asked how caves are formed, Beakman enlists Dave From the Cave, a crusty cave dwelling hermit to demonstrate how acid water dissolves limestone to create them. Then, Beakman is left to describe the types of animals that live in caves, including bats, birds, mice, rats, porcupines, skunks and snakes, along with eyeless troglobites like, cavefish, crayfish, crickets, shrimp, flatworms, snails, and salamanders. After using a solution of washing soda to show how limestone stalactites and stalagmites form, Beakman reveals that the world's biggest cave is in southern New Mexico, while the longest is in central Kentucky.
Sat, Sep 24, 1994
When a viewer expresses exasperation over understanding the concept of momentum, Beakman first calls on Professor Boring, who says it is "the product of a body's mass and its linear velocity." Hoping to improve on this definition, Beakman notes that an object's momentum depends both upon how fast it is moving and how much it weighs, and then uses a bowling ball and a baseball each rolling down a pair of identical ramps to demonstrate. But, showing the results can be changed by altering velocity, he proves that the baseball's momentum can be increased by propelling it down the ramp, and then reminds a skeptical Lester that understanding momentum is critical in designing brakes, launching satellites and building roller coasters. For "Beakmania," Beakman illuminates some facts about the octopus, reveals that there actually was a Tower of Babel constructed in Mesopotamia in the sixth century B.C., and says that Clarence Birdseye developed frozen foods after observing Eskimos. Then, after convincing Beakman to have the "Liza Challenge," Liza shows a befuddled Lester how to make a coin fall into a bottle from a precariously balanced plastic loop. Turning to a series of viewer questions about cows, Beakman begins by explaining that cows don't really have four stomachs, but a single stomach with four separate chambers. Then, after using the Boguscope to show how they chew grass and then regurgitate it to be chewed again, Beakman shows how the stomach breaks down this digested food to produce milk, which is white because of the colors of its component proteins, vitamins, minerals, fats and sugars. Then, after Lester demonstrates his milking technique, Beakman notes that several different kinds of milk, along with a variety of other dairy products including butter, are all made from this single product of cows.
Sat, Oct 8, 1994
Responding to a question about hay fever, Beakman begins by explaining that this common affliction is an allergy ?? a reaction which the body has to foreign substances (known as allergens). Noting that allergens enter the body in a variety of ways, including breathing, eating and insect bites, Beakman takes a closer look at pollen. Showing how it is absorbed via the nose and mouth, he goes on to explain how the body's immunesystem first produces antibodies to fight pollen's allergens, and then histamines to cause sneezing to expel them. Then, after describing symptoms which may indicate allergies, he explains the mechanics of sneezing. After noting how young robins learn to find worms and which fruit is eaten most often (bananas), Beakman calls for a tranquil and quiet "Beak?moment." However, interrupted by the sound of his pneumatic drill, Liza asks construction worker Jack Hammer to explain how it works. Showing her how the drill, commonly known as a jackhammer, uses a piston moving up and down, Jack then tries to explain why these tools always seem to be used most often in the early morning hours. Asked about the first codes and who invented them, Beakman reveals that they were developed in ancient Greece as a way of sending secret military and political messages. Then, after demonstrating one early technique which concealed vital information beneath a layer of wax, he shows how to make a simple code machine used by the Greeks. Finally, after explaining how success at breaking codes influenced the outcome of World War Two, Beakman shows how to make an invisible ink using juice, and reveals that itThomas Jefferson who invented the first code machine.

Asked by several viewers about snakes, Beakman starts by explaining that they are reptiles who can sometimes go for a year between meals. Noting that their skin is actually quite dry, Beakman shows how snakes swallow prey much larger than themselves, and how they use their tongue's keen sense of smell to compensate for their poor eyesight. Then, after claiming that the South American Anaconda can grow as large as thirty feet long and weigh up to 500 pounds, Beakman is joined by Lester and Liza in a musical tribute to these reptiles. Asked why we have seasons, Beakman begins by explaining how the Earth rotates like a gyroscope which has been tilted on its axis. Then, adopting the persona of astronomer Nicolaus Copernicus, Beakman shows how this tilting brings the northern and southern hemispheres closer or farther away from the sun, causing seasonal warming and cooling. Finally, explaining the extremes resulting from this tilting, Beakman shows how the north and south poles each experience months in total darkness and total light each year.

When a viewer asks about tornadoes, Beakman begins by demonstrating a popular household version ?? the vacuum cleaner. Calling on the Boguscope, he then shows how a critical combination of hot air, cold air and the jet stream creates just the right conditions to spawn a tornado. Noting that these wind storms can carry objects such as cars for hundreds of yards, Beakman shows off his own tornado generator as well as how a model of these storms can be made using a pair of plastic soda bottles. After revealing that oils in flower petals cause them to smell, that the human skull has twenty?eight separate bones, and that Osmium is the world's densest metal, Beakman moves on to bee stings. Explaining that an allergy to bee stings can be dangerous if not recognized and treated immediately, Beakman describes how to remove a stinger and treat the wound, as well as what symptoms indicate an allergic reaction. After answering questions about what makes freckles (melanin), when corns dogs were invented (in the 1930's) and whether mosquitoes have teeth (yes!), Beakman turns his attention to a viewer question about fires and firefighting. After first explaining how fire requires a combination of fuel, oxygen and heat, he demonstrates how the lack of any one of these three will extinguish a flame. First showing how firefighters react quickly to an alarm, Beakman follows them to a real fire. With different pieces of firefighting equipment at work, Beakman describes the various types of trucks and tools used to combat a blaze, as well as the type of firefighter responsible for each task. Finally, after Lester's feeble attempt at using a fire hose, Beakman concludes with some lifesaving tips on how to survive a fire.
