Go sweep it back up into the tub. It's still all over your floor endangering your pets!

CO2 does not settle out of air.
Anybody who thinks it does, go collect a tray of it and post pics. :thumbup:



It should be noted I never said you could "collect a tray of it" and was posting a general comment not defending the inaccurate theory of the OP.

I'm pretty sure I've seen room temperature gasses layered, although it could have been from slight temp differences.  This is the real world, diffusion doesn't happen instantly, you can trick it for a bit, but of course it will always win out.

Pretty sure you haven't seen ordinary atmospheric gasses layered like that.
Mythbusters did it once some sort of exotic stuff in an aquarium, I forget what exactly.

Wasn't aiming the tray comment at you specifically.
But if you can collect a tray of CO2 from room air, I'll mail you a dollar. :yesnod:

Certain lakes have been known to burp large amounts of CO2 which crawls over the land (due to it's temp I believe) killing whole towns in their sleep.

Gasses certainly can settle based on molecular weight, but that's not what's going on here.




No, that would be H2S, not CO2. 

When I was working in Prudhoe bay in the 1980s, I once farted after a meal of corned beef and cabbage, setting off the hydrogen sulfide detectors, which caused an entire facility to be evacuated. :lol:

Did you collect it in a tray for later use once it sank back to the bottom of the room? Lol

Ha!
Lakes can burp CO2 as well.
