A magical event in their hands!
You show three rubber bands that have different colours. They choose one to be the bullet and hold the other two bands in their closed fist. You make your hand into a rubber band shooter and attach the bullet band. You shoot it at their closed fist and the chosen band disappears! The band is now inside of their closed fist. As a surprise kicker all three bands are now linked together for a breathtaking finale! This is a rubber band effect that they will never forget!
