Effect: A small transparent Ziploc bag containing rubber bands of various colors and sizes is exhibited to the audience. The magician reaches into the bag and removes one of the rubber bands. A spectator removes another rubber band from the bag.
Taking the spectator’s rubber band the magician stretches both bands between his hands. In a snap, one of the rubber bands is seen hanging from one of the performer’s fingers with the other rubber band dangling from the first rubber band, LINKED!
The linked rubber bands are immediately handed out for rigorous inspection. Even a microscope will reveal nothing fishy!
