In a “Mythbusters vs. Jaws” special airing Aug. 29, the duo determine whether shooting a scuba tank with a bullet would actually make it explode. This was a myth busted by the show a decade ago, but viewers have long claimed their methodology was incorrect. So for the 40th anniversary of Jaws, the MythBusters team are back to test new ideas from the film — and tackle this classic scene in a different way. Other tests include attempting to find out if the sounds of Orcas and the smell of dead sharks repel sharks.
