Nothing to do with the density of the fart, but a lot of temperature differences between the “air” of the fart and outside, apart of the sensibility of the camara, same as you can see at plain sight your breath on cold days.
If the fart has much difference with the temperature outside, the camara will capture it.
Fake, gas isn’t dense enough to be recorded by thermal imaging.

Sadly not, because even a hairdryer isn’t recorded and that’s way hotter than the surrounding area.
You’re arguing against pre-ai video with words.
A quick search shows quite a bit of thermal video of hairdryer blast
Perhaps the video you saw had the air temperature squashed by it’s view of the heater coil
Act choo-choo ally!
