You know, it’s now occuring to me that I have absolutely no clue what Roblox actually is. It’s been around forever, I’ve been seeing gift cards for it in stores for I’m pretty sure well over a decade, I hear lots of talk about all of the dangers and how addictive it is for kids, etc.
But I haven’t the foggiest idea what the game is actually like. To the best of my knowledge I don’t think I’ve ever even seen a single screenshot of it, at least not one that was clearly labeled as being from Roblox.
And while I’m a childfree curmudgeon in my 30s, I do have a few friends with kids that I see with some regularity, and I’ve never heard any of them mention Roblox even in passing.
I feel like I’m in a really weird bubble of roblox-ignorance, I’m not exactly mad about it, but it feels weird that for as big as Roblox is supposed to be that I’ve never seen anyone talk about the actual game, just how big of a problem it is.
I’m sure it’s more complex than I’m making it out to be, but each gas in the air has its own freezing/melting boiling/condensation/sublimation points, so I’d imagine you could just kind of take advantage of that
Basically just cool it down to x temperature at y pressure, and all of the carbon dioxide should be solid, the oxygen a liquid and the nitrogen still a gas, and they’ve all sort of separated themselves out. Fish out the dry ice, siphon off the oxygen, and you’re left with nitrogen.
Might need to do a couple more rounds of that on each of those to account for other gases in the mix depending on how pure you need it to be, but in theory I imagine it could be that simple (again in practice I’m sure there’s probably a lot of details I’m missing)
