They're kings of the myth-busting world! For their season premiere, Mythbusters experts Jamie Hyneman and Adam Savage teamed up with one of Hollywood's biggest directors, James Cameron, to address the show's most requested query: Could Titanic's Jack [Leonardo DiCaprio] and Rose [Kate Winslet] have both fit on the wooden piece of debris and survived together at the end of the movie?

In the exclusive clip below, watch Jamie channel his inner Rose and hit the water firsthand to test the film's accuracy. Using a replica wooden board cut to size — with a few adjustments for buoyancy — the guys start the clock on verifying or debunking this blockbuster myth.

Mythbusters premieres Sunday, Oct. 7 at 8/7c on Discovery.
