This video is a couple of years old, but I just read about it on Forgetomori last night. It shows a folded piece of paper, balanced on an upright toothpick, under a glass bowl. The guy in the video shows how he can make the paper spin with his "psychic powers."
Before he starts making it spin though, he first blows a hair dryer around the bowl to show that the apparatus inside can't be affected by moving air, and then he moves a powerful magnet all around the bowl to show that there's no magnetism involved. The he sits down in a meditative pose and makes the paper spin in one direction, and then another.
You can read the video creator's explanation here. Before you read it though, try to think how he might have accomplished this.
