Cheap Special Effect

Okay this isn't exactly movie related (although it is like a real version of the Sandman effect from Spider-Man 3) it is just so incredibly awesome and unreal that I had to share it. Also it could be used as some weird kind of effect in a movie you want to make. Plus it reminded me of watching old episodes of How as a kid. It's also late on a Friday night in the UK and I've had a lovely bottle of wine. Anyhoo, this is some cornflower mixed with water on a metal sheet and then put on a subwoofer.
