Making a Flamethrower Out of a Fire Extinguisher

    A popular YouTube channel called “The King of Random” has released a homemade project video where they make a compact flamethrower out of a fire extinguisher. Isn’t that the definition of irony?

    This flamethrower is incredibly cool by itself. But what is even more interesting is how simple it is. It is basically built from cheap components which can be found in any hardware store. OK, without further ado, let’s watch the video.

    Components they used are:

    • Dry powder fire extinguisher
    • Lighter fluid
    • Tire valve
    • Brass fitting of proper size
    • Pipe thread sealing tape
    • Hose clamp
    • Lamp wicks
    • Copper tube (faucet supply tube)

    Tools used in this project are:

    • Drill
    • 1/2″ drill bit
    • Center punch (well, a nail, if you will)
    • Tap (matching the brass fitting thread pitch)
    • Pliers
    • Screwdriver
    • Hacksaw
    • Vise or hammer
    • Scissors
    • Air pump
    • Rope to pull the tire valve through the side hole

    If for whatever reason you need to make your own compact flamethrower this is perhaps a good design. However, keep in mind that this is not an instructional video, neither our article is. It is made solely for entertainment purposes and if you use it as a guide you’ll be doing it at your own risk. DO NOT do it if you are not confident enough. This thing will set on fire your property or hurt you if not made or used properly. Follow all the safety precautions and make sure what you are doing is legal in your area.
