I have an extra fire extinguisher around the house and i was wondering if there was an easy way to refill with an air compressor and lets say rubbing alcohaul for a flamethrower. i dont want to waste the extinguisher if what i am trying to to cant be done because my parents might get pissed. if anyone has any idea on how to refill a fire extinguisher at home with an air compressor let me know. thanks.

air compressor = big no no
you have to use something with out oxygen or else there is a risk of explosion, i'm not sure since the fuel is liquid.

if any 1/4" or 1/8" fitting fit in your nozzle, add a quick disconnect for easy connection to a gas source, like a male coupler,

i have no clue on how to fill with liquid, i guess you can tap a 1/8" npt thread on the side of the tank and plug it when you done filling it, or get some GREAT welder to attach a large ball valve on it or something

this brings an idea from my head, can you pump in waste air?
have something like a sealed fishing tank with you pump in it, you burn something in it until it runs out of oxygen... repeat...

i'm bored

just twist the top of the fire extinguisher to get it off and instead of filling it with air get a propan bottle and get that attached by attaching a hose to the exinguisher bottle and then attaching the hose to the propane bottle but be carefull because some fire extinguishers have plastic insides

You could use a inert gas init like nitergen or CO2

Yep, CO2 sure is flammable.

noname I'm going to hope that you are being sarcastic! If you are then I'm still not sure what your talking about!

Please tell me that you know co2 is not only inert but it's used in some fire extinguishers.

maybe you guys took this the wrong way...why would i use an inert gas if im trying to make a flamethrower? and saladtosser cant i just unscrew the top to fill with liquid and screw it back on then compress with air?

i would personally prefer u did not put something flammable into a fire extinguisher, its the complete opposite of what it is meant for, not to mention, VERY illegal.

CO2 isn't too flammable. WOW suggested to pressurize CO2 in the extinguisher to spray out the alchohol.

C02 is exactly the opposite of flammable, and you pressurize the chamber with C02 then in the rare event of a flashback, you dont explode

Just use propane.... there won't be enough O2 in the extingusher to support combustion.

They could be tho and if it flashes back like some1 said it could keep it from blowing up.

i understand what you were saying about the c02 so it doesnt flash back in the bottle. it would be a good idea with something more combustable but i dont think alcohaul would explode in an enclosed space. if it lit on fire in the bottle just close the valve and it will burn of of its oxygen up in like five seconds.

One word-Vapors, If it is burning in the bottel it will explode!!

well considering its alcohal, it wont burn for more than 5 seconds, and its in a metal cylinder that is made to hold alot of pressure, i really dont think it would explode.
