Magic Tricks

This is one of those awesome effects that you can perform for 1 or 500 and get the same reaction. There is (relatively) no sleight of hand involved, so you can focus completely on presentation. This is meant to be fun and the cards can be handled fairly freely. When they just toss them over their shoulder, you've got that fun moment in magic (everyone loves making a mess) and there's nothing to really worry about as far as anyone seeing anything go wrong.

The only downside I can see is that the deck will eventually start to wear out if you do this regularly and they don't currently have an inexpensive replacement for it. Also, the effect can't be repeated for the same audience (another good reason to be able to buy a second deck and jumbo card). They do offer several alternative handlings you can use to keep the cards new longer, but seeing them tossed is a lot more fun.
