Aren't you just seeing the lack of water rather than actually seeing the oxygen?

[-] whaleross@lemmy.world 8 points 11 months ago

And what is inside the bubbles instead of water?

[-] Burninator05@lemmy.world 21 points 11 months ago* (last edited 11 months ago)

nitrogen โ€“ 78%

oxygen โ€“ 17%

carbon dioxide โ€“ 4%

other gases - 1%

Ehhh, if you made a translucent sphere that could hold a vacuum you would get the same outcome l.

[-] Buddahriffic@lemmy.world 2 points 11 months ago

It would be close but but exactly the same. A vacuum would refract the light going through it differently than a bubble of gas. Though I think it would need to be pretty big to see it with the naked eye.

[-] cows_are_underrated@feddit.de 1 points 11 months ago

You see the a bubble of gas(and therefore the absence of water), not the oxygen itself. You could use only nitrogen gas and you couldn't tell the difference.

[-] Buddahriffic@lemmy.world 2 points 11 months ago

There won't be that much CO2 for a long time, even if we increase our carbon output. Currently it stands at around 0.04%, third to argon at a bit under 1%. Oxygen is just under 21%. Oxygen and nitrogen together make up over 99% of the atmosphere (at sea level). That's for dry air, otherwise water vapour is at around 1% and the others reduced to fit that in.

Ah, but this is a bubble blown by a person. Exhale would have less oxygen and more CO2.

[-] Goblin_Mode@ttrpg.network 1 points 11 months ago* (last edited 11 months ago)

Well if we're gonna get specific then if your blowing the bubbles I would assume it's largely carbon dioxide lol

[-] Karyoplasma@discuss.tchncs.de 1 points 11 months ago

Unless you are blowing from an oxygen tank. You don't need to use your lungs.

[-] Goblin_Mode@ttrpg.network 1 points 11 months ago

You know what, fair enough lol

Maybe, but its a similar case with a mirror, unless its dirty or the backing is flaking off.
