I would really recommend you get the sponge balls because you can add a lot of variety and
versatility to your routines. You have to practice a lot though but at the end you can get great
reactions out of simple magic. Oz does an excellent job of teaching you some routines, that are
powerful and yet very easy to learn. I'm still working on my retention vanish, I can't wait to go
out and actually amaze some people with this.
