Watch Mythbusters season 16 episode 1 online for free. The MythBusters celebrate their explosive history with two spectacular big bangs. In MacGyver Cement Truck, our mullet-wearing hero discovers a mail truck full of TNT. Thinking quickly (as he does), MacGyver has a nearby cement truck dump its load onto the truck to smother the bomb. But would it work in real life? Then in Hovercraft Hijinks the guys tackle the one explosive technology they’ve yet to come across: landmines. Can a minefield really be safely traversed in a hovercraft?
