At 20:55 Philip carries the anti-matter containment device as though it only weighs a couple of pounds. But later Trevor has trouble carrying the device and says it's very heavy.
At about 37:20 Trevor says "There won't be a warning. It'll just go boom." But at 38:18 the device starts beeping.
The purportedly high pressure water line that the team causes to leak is described as 4 gallons per minute or roughly 15 litres per minute. This is about the average for a domestic water supply, and nowhere near industrial high pressure which can be in the hundreds of litres/gallons per minute.
CORRECTION: At 33:49 Carly states the water flow is 14GPM, not 4.

They said the Antimatter explosion would be "In the megaton range", but it was later shown there was only 10.3 grams of antimatter (20.6g of mass converted to energy ... E=MC^2). For the explosion to reach the equivalent of 1 megaton they would have needed AT LEAST 23.3 grams.
This is beside the fact that Antimatter has only ever been made in nanogram quantities (billionths of a gram) due to complexity, cost and danger.
Out of the thousands of travelers the team is stuck with a drug addict.
