I do two card tricks. Just two. They are both beautifully simple tricks that are self-working, need no gimmicks, and require no sleight of hand. To people who don't know the secret, astounding. I have only ever revealed how I did one of them to 2 people: My wife, and my daughter, both on separate occasions, and both times because they forced me into revealing one of the tricks using their feminine wiles. (my wife made promises and threats, my daughter quivered her bottom lip and filled her eyes with tears) Both their responses when I explained the trick were the same: "But that's cheating!" That trick, to my wife and daughter, has lost it's beauty and mystical intrigue. I'll never reveal to them how the other one works.
But I still like to know how tricks are done!
