A pen rests inside of a cup. You concentrate, stare at the cup, and something strange happens--the pen jumps out of the cup! With Jump you can make a pen, pencil, spoon, or straw jump out of a cup or glass. You can even make popcorn pop right out of its bowl! And no one will know how it works because they can examine everything afterwards. Jump! is a state-of-the-art electric device that operates with a standard 9-volt battery. One battery will cause over a hundred jumps! Battery included! The device stays hidden away from the action leaving no clue to the telekinetic mystery.
