How to Perform a floating cup magic trick
This floating cup is lighter than plastic and lighter than glass, but is it lighter than air? Tune in to find out! You will need a styrofoam cup and scotch tape.
Sometimes we use materials that require adult supervision... like scissors, so make sure you have friends and family around whenever you do magic tricks.
1. Preparation: Tear a small hole in the back of the cup about the size of your thumb. Alternative: Make a small loop of tape and affix it to the back of the cup (it should have some slack in it big enough for your thumb).
2. Performance: Hold cup in between hands with thumbs at back. Place your thumb into the cut hole (or through tape loop). Slowly move your fingers away so that it appears as though the cup is floating in between your hands.
