There is a little experimenting to get the technique correcct, but it is not hard. Great for a
beginner (my nine year old enjoys this). When I first did it I was surprised and it took me a
little while to figure out why it worked. No gaffs, you can let a spectator try it for themselves.
Doesn't take up alot of space, doesn't cost much, a fun addition. Great for young magicians as
well.
