The phrase "DIY pyrotechnics" seems more likely to wind up on a police incident report than an art website, but the way inventor Colin Furze straps blowtorches onto everyday objects certainly is an art. The latest Furze gadget to gush flame is a hacked and hacked-apart Frankenguitar, á la the Doof Warrior from Mad Max: Fury Road. Thanks to a bit of Arduino magic, it can shoot fire in time to the music radiating from its hybrid amp / gas tank. If heat's not your thing, Furze also made a companion bass guitar that spews smoke and has built-in strobe lights, completing the 80s shock-rock tour de force.
Furze has strapped flamethrowers, fireworks, and jet engines to various objects in the past, including go karts, a windmill, and his own arms. With the amount of firepower he's packing, he could start a flame war with Rammstein. He'd probably lose—I mean, just look at these guys—but at least the king of "Don't try this at home," would go down in a blaze of glory.
