Hoaxing an infrared fart
Uploaded by: wbeaty
Video Description:
"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

Tell a friend:














And it COULD be entirely simulated with high-end CGI. It could!> but i cant say either way
Sure you can. Hoaxers only survive because we can never be *certain* whether it's a hoax. But nothing is certain. Ever.
So think probabilisticly rather than in terms of certainty. Enough info exists to make a decision.
2. A hoax is trivial: stand sideways and hold a can of freeze spray behind your body.
3. In the fart video, the gas penetrates their pants as an incredibly narrow jet. Is this person some kind of alien? That, or it's just freeze spray.
On the other hand, "GasFindIR" cameras have a narrowband filter and gasoline fumes become visible: youtube com/watch?v=j_NswgZFgzA So was it a real fart? No, because see #3 above.
I thought I already had! I hadn't imagined that any more would be needed.
It's a very simple and obvious hoax, and the lies are exposed if you know two things: cheap FLIR cameras see "black equals cold," and hydrocarbon gas is invisible.
When I made this video, I hadn't noticed the thinness of the stream. That is supporting evidence. But the key fact is: black equals cold (extreme cold in fact.)
This camera works that way, but if you want a false-color display, you need a more expensive version like this one:

is FLUKE better?? explain please
Nope. Watch the video carefully, and you'll see large amounts of hot gas *not* showing up. Perhaps if the gas were around 200F you'd see white flamelike images.
also, bum joke...
