Watch Shark Week Season 21 Episode 1 Online

Using their signature sci-tech style of explosive experimentation, the MythBusters hit the deep blue from California to the Bahamas to investigate myths about sharks. They are honing in on some doozies this year: Do dogs attract sharks? Do the vibrations caused by a flapping injured fish attract sharks? Does chili powder repel sharks? And hosts Adam Savage and Jamie Hyneman create the ultimate SHARK WEEK build – a 16-foot-long robo-shark!
