I'm surprised Adams is selling this. The effect is really cool. But the method is unoriginal.
However, if you want a really cheap version of this classic trick, go for it. The rubber you get is
pretty good. Plus it shows you a really cool illusion you can do and not many people know. One
downfall though is that you need to set up before you perform and it can break if you do it to many
This is the same effect that Penguin used to sell called "Pena-coin" but without an Instructional
Download. You borrow a coin. You introduce a glass with a square of solid rubber on top held with a
rubber band. You put the coin on the rubber, push, and POP! the coin goes right through.Even the
spectator can push the coin through! Everything can be examined. Every time you perform this you
will fool yourself. It just looks so impossible. The set-up will take about 25 seconds. Go get it!
