Are farts ever visible?

I mean urine ranges in colour from clear to yellow to brown and if your really sick red and black.

So does sh*t.

So can your body ever get so sick that it starts producing a visible gas in the bowels? Or can you introduce something to the body to make it do this?

Then we could answer the age old question, who farted?

:eek: :smiley: :eek:

God, I hope not. Then I couldn’t blame the dog.

You can introduce a flame to the offending orifice.
That would probably show up a color and if may produce different e color depending on the consituents of said anal expulsions.
Having said that of course, you would need to set a benchmark on what was normal so you could compare different colors as being ‘better’ or ‘worse’.
You could end up with a color wheel, so you could check if your anal expulsion was highlighting an illness that you didn’t know you had.

One night we tried to solve this question in college. But the room was kinda dark, so some guy used his lighter to try to help.

I can truly say that they were visible that night.

If you lit a fart and viewed it through a spectrometer, could tell what the person had for lunch?

When I was little I was swimming with my father in the sea, I was wearing a snorkel and mask. During my underwater investigations I saw bubbles coming out of his swimming trunks.

He was hugely cross and embarrassed when I pointed out I’d witnessed him farting.

You can see them as a little cloud.

Only if you’re naked, of course. And outside in the cold.

Don’t ask me how I know this.

I’ve seen a rhino fart, and it was verry funny.
In a wild animal preserve in South Africa.
Rhinos often coat themselves with dust to keep flying insects away from their anus. But when they fart it’s like someone squeezing a talcum powder bottle.
And it goes on for 20-30 seconds!

oops, brainfart :o

Satellite reconnaisance of the earth suggests that most of the world’s methane comes from the american south, and central america.

My guess is that if you insert one of those birthday whistles that roll out when you blow 'em in your anus just prior to a rectal outburst, your flattus would be at least as visible as the rhino duststorm.

Reminds me of a joke I heard as a kid. I don’t rememebr the set-up, but the punchline was “Catch that and paint it green.”

Now let’s see who can come up with the best set-up.

Most gases are totally transparent. I’ve seen a couple of colored ones: chlorine, bromine, nitrogen oxides.

Hey, the visible spectrum is a human conceit. If you could see all the way down into longwave infrared, you’d see the absorbtion bands of gasses as various colors. And IR-vision alien could see who farted. (Or, if you had a thermal scanner, for you the hot gas would be visibly red hot!)
