In this fun experiment you can levitate a ping-pong ball. First punch a hole at the end of a fat straw and seal that end. Now place a ping-pong ball on the hole and blow from the other end. A stream of air will come out and keep the ball hanging in the air. The stream of air will keep the ball afloat.
