להקפיץ לא להקפיץ כדור

This is a funny trick disguised as an IQ test. You show your spectator a normal looking black ball and tell them that it tests the thrower’s IQ. So you throw it onto the ground, and it bounces over your head. Then after this demonstration, pass it to a spectator. Well, after he throws it to the ground, nothing happens and it stays stationary on the ground!!

The spectator is welcome to check and verify the ball! But meanwhile, the ball is indeed unmoving on the ground!

This is good for close-up shows as well as interactive stage performances.
