Hoaxing an infrared fart

"Freeze spray" is cold and looks black under FLIR thermal camera. But propane is invisible. (Propane and methane are basically the same to thermal cameras, in the 3-micron long-IR spectral region.) "Thermal Eye" camera TSC by L3/Raytheon

"ooo i can heat up my skin....... OW!" hahaha nerd alert!!! but seriously can someone thermal image a fart for real please... it'd be oh so amusing.

> thermal image a fart for real

Normal thermal cameras can't see farts (gas not nearly hot enough.) Perhaps a narrow band "GasfindIR" camera could do it.

How about heating the propane canister to 98deg F - and then bring it into a cooler room - and set the IR to the correct wavelength? How about that? huh? can you do something that simple? go ahead - I'll hold my breath

> heating the propane

Doesn't work. Can you see the 98F air plume from my arm? Nope. On cheap thermal cams, gas won't appear white unless it's about 150F hotter than ambient.

And if it's black, then it's chilled way way below 0deg.

Expensive "gasfindIR" cameras might be able to see farts though. But it certainly wouldn't look as if someone shooting a cold jet from a spray can held behind their leg. What *would* it look like? Well, imagine if you set off a smoke bomb inside your pants.

Be nice to nerds... Chances are you'll end up working for one.

No, but look up infrared fart and you'll see what he is referring to.

[HeroinMethod]

@wbeaty or if you lit your fart with a lighter

[Keabiu]

This proves nothing.

@houdiinii Wow way to be oblivious champ..... right over your head.

[houdiinii]

@flatblackstrat the guy at the airport isnt farting at all, he had a hidden gas cylinder.

@wbeaty

I have a gasfindir camera and you can see methane gas. You can also reverse image polarity so it could be black or white.

Im pretty high right now, and this is very strange.

[packagewarren]

very weird, very very weird.

[flatblackstrat]

So the guy at the airport is farting blizzards?

[MichaelJae]

I'm gonna stick my neck out and call fake on this one. The spray doesn't come out from his ass.
