The “make money float” magic trick is an illusion in which a bill or bills appear to float in mid-air. It is a popular trick performed by magicians of all skill levels, and it can be easily learned with a little practice. The trick is based on the principle of forced perspective, which is a technique used to create the illusion of depth on a flat surface.
To perform the trick, you will need a bill and a piece of thread. First, fold the bill in half lengthwise. Then, take the piece of thread and tie it around the center of the bill. Next, hold the bill between your thumb and forefinger, with the thread hanging down. Now, slowly move your hand up and down, and the bill will appear to float in mid-air.
