No, gotta be argon. When I tried it, you get something like a thermite
reaction where the molten aluminum takes the O2 off the CO2 and there's all
this amorphous C spraying around as soot.

Pretty strange to think that (oxidized) soot is what makes beverages fizz.


I wonder if helium will dissolve in water. "Helium-ated" water
probably wouldn't have any flavor, but it might make some hilarious
pop for the kids talking like Donald Duck.


Particularly funny if they were "burp talking" like some folks with
laryngectomies (and some kids too) do.
