How Do You Make A Pen Spin On A Table Without Touching It?

My friend at school can do it, it looks so real. He just looks at the pen and puts his hands over it and he makes it spin without touching it. He doesnt blow on it, he doesnt tilt the table, he doesnt have any strings attached. It looks like magic. How the hell does he do it? Ive asked him but he says he wont tell me unless I give him 10 dollars. Today, he also made a pen move across the whole desk without touching it………im not lying, im serious, its impossible!!!
