I NEED One: Gas Powered Vortex Cannon
We've allegedly seen the world's largest vortex cannon before, but that thing doesn't hold a match to the power of this sucker, featured on the BBC's Bang Goes The Theory. The goal was to use this cannon to recreate the big bad wolf's huffing and puffing from Three Little Pigs. Now I don't want to ruin it for you, so just watch. Then, you and I are building one and robbing a bank. I've always wanted to wear a ski mask!
Thanks to Ross and James, who'll huff and puff and then use dynamite.
