Facebook find!

A friend of mine posted this on his facebook wall, and I really am intrigued by the method, So I plan on making this, But i haven't gotten a chance to as of yet, and anyone who is on facebook knows that if you see a post today in two weeks you may never see it again. So i thought i woudl scarf the link so that i can at least have it at my fingertips and i can make it later.
