"MythBusters" Shop: M5 Industries

MythBuster Jamie Hyneman started M5 Industries on his own before his career took a left turn at Discovery Channel, and he somehow manages to maintain it despite the breakneck shooting schedule he faces. The shop serves as the build zone and testing ground when the myth can be contained inside the warehouse walls. Many times, the gang has to go off-site in order to blow up or crash something large or dangerous, but the M5 parking lot has also seen its share of pyrotechnics.

At one point there were three buildings -- M5, M6 and M7. After disturbing some quieter neighbors in their industrial park, M6 closed shop, and now the more private M5 and M7 serve as the show's home. M5 is where Adam and Jamie get most of their work done, and it also houses the studio set where they begin and end each show. If some messy testing needs to go down, it happens at M7.

The M5 shop is packed to the gills with props from the 300-plus myths the gang has put to the test. Just don't try and find the original rocket car from the pilot episode -- Jamie sold that one after thinking "MythBusters" may not be in for a long run. Aside from being an unofficial "MythBusters" museum, M5 is a working shop, so there's virtually every kind of tool on the planet to help the team accomplish whatever they can dream up. There are metal lathes, a welding station and every kind of tool, nut, bolt, screw and material you could think of. There's an old card catalog full of small motors and a computer-controlled milling machine that does all the cutting automatically. There's also a cache of safety and rigging gear to make sure everyone walks away from each test unscathed. Throw in some crash test dummies, models and heavy machinery, and you have the means for some serious myth busting.

Jamie and Buster test whether or not punching a shark in the nose will send it swimming off (plausible.)
