Put simply, this episode is vintage, explosive MythBusters. Adam and Jamie have unfinished business from their Shark Week special, where they shot and then exploded a scuba tank.

Meanwhile, Tori, Grant and Kari go back in time to test some prototypes from the past. They all sound highly dangerous, and they probably are ... After all, they're tinkering with engines fueled by gunpowder!
