No oxygen inside the reservoir to combust with. Even when the reservior is half-empty, the strong scent of the WD-40 or the washer fluid is because they evaporate quickly to fill that space, rather than letting air into the thing. And any air that did get in would get used up pretty fast

The lack of oxygen in the tube. If they let the bottle run out though and they get mist in the tube, they're in trouble.

His first sentence was accurate, but the rest of his post was false. When you pump up the reservoir, you're pumping air into it. That air when mixed with the WD-40 is combustible. It evaporating quickly has nothing to do with it not burning. On the contrary, that vapor is very combustible. Normally the tube in the tank will only pick up liquid, so you don't have to worry about fire travelling from the nozzle through the liquid and into the tank since the liquid can't burn without oxygen. But if the liquid in the reservoir runs out and the tube sucks up air+liquid, you're in trouble.

Thats what a flame arrestor is for.

Flashback arrestor. :)

Also don't use air to pressurise the vessel. Use argon, co2 or nitrogen. You could use freon but you'd better not do this in an enlosed space unless you enjoy getting your lungs seered with phosgene.

It would probably burn nice with propane as the carrier.

Either way, using a super soaker as a flame thrower is pretty dumb. Go to a PCO supply store, lots of goodies there. After all, outside of a military flame thrower, what other (fun) way is there to take down a nest of European hornets 40' up in a tree?

The dumbass should've flamed his friend who's doing the recording. Now that would be a bit more entertaining.

its too bad that i know this statement is wrong.

WD= water displacement, but i wasnt sure what the 40 stood for so i looked it up.

WD-40
