In Mad Max: Fury Road, the Doof Warrior plays heavy metal on a flamethrowing double-neck guitar. After watching the movie, Caleb Kraft decided to build his own "adorably dangerous" version of the instrument: a flamethrowing ukulele. Kraft used a modified caulking gun to squeeze butane into a hose and added an igniter switch. With zip ties, he attached the whole apparatus to the back of a ukulele, creating a cute, strummable instrument of destruction. "Movies and videogames are such easy inspiration," Kraft says. "They are the manifestations of what we think would be awesome to exist."
