Coats, Tapes, and Rings

Two boys are asked to come up on the stage to assist with the experiment. Each boy is given a piece of tape about sixteen feet long to examine. One boy is asked to remove his coat. The performer passes the two pieces of tape through the sleeves and then ties the tapes in a single knot. Two examined rings are then slid down on the tape to the single knot and another knot is tied over the rings.

The other boy is asked to take off his coat and performer passes the two pieces of tape through the sleeves of the second coat and ties another knot in the tapes. The ends of the tapes are given to the boys to hold. Then in a few moments performer removes the first coat, then the rings, and finally the second coat, leaving the tapes intact stretched between the two boys.
