This guy starts off with a piece of glass. You can see the slats in the pallet below. Then he pours a bucket of liquid silver nitrate on it. You can immediately see the guy's reflection, but somewhere along the way, the slats underneath disappear and the glass is now a mirror! It will probably be a while before the mirror is dry enough to be picked up. If you want to try doing this yourself, the internet has instructions. -via Digg
My mother had mirroring recipes that involved spent photographic solution and sugar. Never tried them myself.
