Make: Community Editor Caleb Kraft created a flame-spewing ukulele inspired by the flame-spitting guitar used by the Doof Warrior in Mad Max: Fury Road. The contraption was built using a variety of easily purchased items, but Kraft cautions any would-be tinkerers that it’s rather dangerous.
I didn’t want to try to replicate exactly what he had, and I also wanted to scale things down to be marginally safer. My version can be built from hardware store parts in a very short amount of time.
