According to the series' stunt coordinator in the Charmed season eight DVD bonus features, the effect of Prue's telekinesis destroying the attic in this episode was accomplished by rigging every object in the room to strings which were then tied to a Chevy Suburban truck. When Prue flicks her hand on camera the driver is cued to accelerate the truck on the other side of the attic window. This caused all the tied objects to crash through both the attic window and wall to dramatic effect.
