Purchase a magic coin from a magic shop. If you buy a magic kit this trick might be included.
Inspect the magic coin to make sure that it is held together with elastic bands-it will bend in two or three pieces.
Give the coin to a friend in the audience or put it in a jar of coins and select the coin from the jar yourself. You must have the trick coin in order to bend it like superman.
Write on the coin on both sides with a Sharpie-don't smudge the ink-you can draw lines or write your initials.
Show the audience one more time that the coin is real and that it has writing on it.
Grab the coin between your index and middle finger and your thumb. Make it look like it is a real struggle.
Adjust the coin so that it catches in just the right spot to give the illusion that it is bent. Show it to the audience and enjoy the applause.
