Magic Tricks

I already knew about this math puzzle. I purchased it b/c I never found any presentations of it and the description made it sound like he came up with some brilliant presentation. I bought it only to see how someone else performs it. It was an extreme disappointment. Instead of having the tradition way of having one person count all the pennies, he has 4 people each count rows of pennies. Unbelievable that a cd was made of this. If you don't know how it is done, still definitely not worth more than $10 in my opinion. Don't buy this.
