A man grabbed a large cup made of Styrofoam. He went outside and found a person. He said to the person, "Watch this!"
Out of nowhere the cup appeared to be levitating. How did he do this?
AnswerHe did it by poking a hole in the back of it. He then put his thumb slightly in the hole, and kept all his other fingers outward. He then moved the cup a little to the side, so the thumb is invisible from an angle. Then, he opened all his other fingers in a butterfly formation outward.
You can do this with lots of practice in the mirror. A plastic or paper cup will work too.
