Who doesn’t like flamethrowers? Everybody but space bugs and fire extinguishers, that’s who. Now, Allen Pan of Sufficiently Advanced just went and made the best flamethrowers ever. You see, these wrist-mounted fire shooters activate their wearer throws a punch. Awesomesauce!

Allen created these punch-activated flamethrowers as a tribute to the firebending in Avatar: The Last Airbender and The Legend of Korra. Their core design is basically a butane fuel chamber and a solenoid valve, combined with a modified arc-based lighter to spark it to life. An Arduino Pro Mini controller and an accelerometer detect the punch movement, and trigger the spark and the valve when it’s time to fire up.

But enough tech talk. I know you want to see them in action, so here goes:

If you dare play with fire yourself (and I’m not advocating this), drop by Allen’s page over on Hackster.IO, where he’s putting together a complete DIY build log for these amazing wrist weapons.
