this is a pretty good party trick. tip your head back and pucker your lips, then blow out to make a strong stream of air straight up. then place the ping pong ball in the air stream and it will float! tip: keep the air stream strong and constant and you should be able to keep it up for 4-5 seconds before gravity takes over.
