Wrist-Mounted Flamethrower
This outrageously perfect wrist-mounted flamethrower is the third version from a pyro-genius. It took four years for Stephen Hawes to make this spectacle, which uses a camping propane tank, a modified taser as an ignition, and a custom circuit board. It may not be the safest wearable, but it's guaranteed to make you look tougher than anyone wearing Google Glass.
