Testing A Flamethrowing Tuba: Fire In Your Hole!

Taking the marching band to its logical next level, this is a video of MasterMilo testing the flamethrowing tuba he built out of a tuba (shocking) and chainsaw motor, which shoot a jet of ignited propane as its wielded. That’s cool. The bell of that tuba after shooting flames? That is not cool, that is probably HOT. Definitely not something you’d want to pretend to sit on like a toilet right afterwards, no matter how badly you’re convinced farting into the fat end will reduce the sound to a mouse squeak when it exits the mouthpiece.
