Make editor Caleb Kraft shows you how to build an "incredibly dangerous" flame-shooting ukulele for your Mad Max Fury Road LARPing adventures, inspired by the Doof Warrior bungee-lashed flaming guitar-playing character.
Prepare your fire extinguisher.
Place a fuel canister in the caulking gun and place the plunger flush against the bottom of the canister.
Depress the igniter and verify that you see and hear the spark.
While depressing the igniter, squeeze the caulking gun handle. You should hear fuel being released and the spark should ignite it as it leaves the nozzle. You may have to experiment with placement of the spark leads for optimal ignition.
