Mythbusters' Kari Byron Hosts 'Large Dangerous Rocket Ships,' 7/5

This Independence Day, Science Channel invites viewers to celebrate the holiday with a front row seat to the premiere, high-power rocketry event in the country - Large Dangerous Rocket Ships (L.D.R.S.).

Kari Byron, co-host of MYTHBUSTERS, guides viewers through the event as the most fearless, hardcore amateur rocket builders from around the country gather in Lucerne Valley, Calif. to launch more than 2,000 of the biggest, cutting-edge homemade and hand-designed rockets on Earth.

Propelling tens of thousands of feet in the air in mere seconds, these rockets travel into the sky at mind-blowing speeds and so high that the Federal Aviation Administration (F.A.A.) has to shut down airspace over the event. All year long these backyard rocket engineers strategize, plan, tinker, and toy with science and engineering to produce some of the most insanely high-powered rockets anyone has ever seen from traditional rockets to port-a-potties and washers or dryers.

All hunger to send their homemade contraption the high into the sky, and some endeavor to send their rocket 100,000 feet high -- a mark that has only been hit once.

L.D.R.S. 2010 premieres Monday, July 5 at 9 PM ET on Science Channel.
