NB: For the non-divers who subscribe, we use the format of “XX / YY” to denote the gas in a tank whereby XX is the percentage of Oxygen (O2) and YY is the percentage of Helium (He) — the remainder is assumed to be Nitrogen — and we put stickers on our tanks with that information.
So, any technical diver would know that “0/100” is pure helium .
I got up this morning and had a little fun in the garage!
Happy Valentines Day to everybody and Happy Birthday to my mom who just so happens to have been born on Valentines Day.


Happy Birthday Mrs Eldridge!

Never heard of 0/100. Most common usage that I’m familiar with is 4.5 or 99.995—four nines and one five. Gas houses sell it as UHP or “ultra high pure.” Speaking of which, I need to go tomorrow to pick up more. The stuff is damn expensive nowadays. I hope your lady appreciates how much you gave up for her. 😉

Haha! She definitely does. 🙂
