For almost a decade, Grant Imahara was one of the hosts of Discovery Channel’s Mythbusters. Using a blend of science and fun, he put urban legends to the test, sometimes with explosive results. Since joining the team in January 2005, Grant tested hundreds of myths, and in the process swam with sharks, hung from the skids of a helicopter, fired cheese out of a cannon into the San Francisco Bay, allowed 25 tarantulas to crawl on his head, dropped a BMW from an aircraft, sliced a car in half using a rocket sled, destroyed so many cars he’s stopped counting, and built many, many robots, all in the name of science.

Before joining Mythbusters, Grant spent nine years working in special effects as an animatronics engineer and modelmaker for George Lucas’ Industrial Light and Magic. He worked on numerous blockbusters including the Matrix sequels, A.I., Galaxy Quest, Terminator 3, Van Helsing, and Star Wars: Episodes 1-3. He put the lights in R2-D2’s dome and gave the Energizer Bunny his beat. He created the often rude and irreverent robot skeleton sidekick Geoff Peterson for The Late Late Show with Craig Ferguson.
