I had the great honor of working with Reza as a guest on one of his shows.  I like this illusion because it allows me to bring a completely unprepared volunteer up on stage but also because I think the message is a positive one for young kids to hear.  Magicians will enjoy seeing a very unique method for a levitation.  While I won't give out secrets, notice that you can see under the platform and it is only in few inches off the stage.  Hmmm.
