I've always been a huge fan of the torn and restored newspaper effect. If you've ever seen The Recruit, there's an awesome torn and restored performance in the beginning. That was one of the selling points of that DVD when I bought it.
With Osterlind's, unlike the No Tear Torn and Restored sold here at Penguin, you get to give the newspaper to the spectator when you are done performing it.
What could be better than that?
The Radar deck is very simple to set up. There is nothing special needed to make this deck. Most gas stations, supermarkets, convenience stores sell the one thing that you need. May have to hit a couple stores up to get enough of them though as most stores usually don't stock very many at any given time.
It will take you about 10min tops. You most likely already have the materials for this deck sitting in a drawer or box somewhere anyhow. If not, it will cost you at most, $25 to make.
Cell phone effect is insanely simple, and devilishly powerfull.
Glass of water production is more of a stage effect. It's cool, fairly easy to do, but it's not for me personally.
I don't know if I'll ever perform it, but I'm working on a smaller, two or three shots of tequila (for the ladies and myself to enjoy) production modifying his technique so I can do it in a bar with a borrowed, empty purse or something.
