Happy Fourth, Everybody!

To celebrate we've got a super fun DIY project from Grathio Labs - Matchstick Rockets! Check out his great instructional on Vimeo, or head straight to the lab for the step-by-step and downloadable PDF. Remember, aim away from your face and never play with fire.

From the look of it, Grathio Labs is a great place for all sorts of fun. A Jeep-mounted potato cannon? Now THAT'S how we celebrate America!
