One Hand Clapping

This is a technique primarily used by beginners to get the feel for flipping (although it can look fairly impressive if you put some flair on it). Basically you're following the motion of your fingers slapping against your palm, only don't slap them just yet-- you'll want to start pretty slowly so you can gauge revolutions.

1.) Open your hand with your palm opening upwards
2.) Lay a coin down over your middle and ring fingers about a coin-width from the tips
3.) Quickly close your hand. You want to angle your hand down in time with your fingers closing up so the coin slides straight up

Try to keep the coin spinning at a constant rate proportional to the speed at which you close your hand. The best way to do this is to close your hand at the same speed and work on your release until you get the coin doing the same number of revolutions consistently, or just shoot for a certain number of revolutions and adjust your handspeed.

Also watch out for the coin backfiring into your face. This is usually caused by beginners slapping their hands closed too hard before understanding all the mechanics, but it's a common injury for pros as well so always be careful!

This variant on the standard flip will give you good control of your coin, as well as make you look pretty suave in the hotel bar. Did she just ask you for a quarter to play pachinko? You bet she did. Flipping just got cool again.
