Balloon Burster (Online Instructions) by Taiwan Ben and Jeimin Lee

Telekinesis in under test conditions!

You give a spectator choice of any color balloon. The Balloon is blown up and placed on a balloon stick, the stick is then handed to the spectator to hold. You NEVER touch or come near the balloon again. As a matter of fact, you sand far from the balloon and your spectator! You concentrate your mental powers on the balloon and everyone gasps when they see you have POPPED the balloon with your mind! 

BALLOON BURSTER is 100% completely self-contained!

The microelectronic and ingenious system will do all the work for you so you can focus on your presentation.
