How to skip stones

I have a checklist a mile long of things I want to learn how to do, and skipping stones is one of those things. My dad was always able to skip stones really well (seems like one of those things that dads just inherently know how to do) but mine always seem to sink without a single bounce.

This article explains that the secret is to toss your stone at the "magic angle" of 20 degrees. Aha! An excellent tip that I will try to remember the next time I'm chillin' by a lake with some perfectly round and flat stones in my pocket. (Not sure when that will be...) I know it will take much practice, but I'm determined to learn how to do this!
