Exploding Rainbow

Gav and Dan, the Slow-Mo Guys, are always looking for something to film with their high-speed cameras. Something that people will find interesting, but more important, things that will look good. Explosions? Yeah! Pretty colors? Yeah! So they gathered bags of paint powder and vehicle airbag devices and headed out to a quarry, far from anyone who would be bothered. They do it three times! That must've cost a fortune in airbags. The result is not as educational as some of the other videos they'd done, but it sure is pretty! (via Laughing Squid)
