The Disappearing Quarter trick is such a fun trick to perform and has absolutely NO setup that could give the trick away! I learned this trick in High School from one of my best friends and have enjoyed showing it to my friends ever since. One of the great parts is that if your audience is not the most observant you could even demonstrate with 4 different coins and sometimes not have the person catch on (Yes I have actually had this happen). All you need for this trick are 4 matching coins and the ability to talk with your hands.
