I need help

[blackheart3]

I bought a helium tank once, but I didn't realize that party gas tanks weren't 100% helium. I wasted money for nothing, and I don't want to lose mone again if I buy a new one. I need more instructions on the helium tank. Has anyone here tried the method? How many liters and bars would a tank need at least? I'm really anxious because I want to try to buy one as soon as possible. I would appreciate it if you could answer me.

i had no idea party gas tanks weren't 100% helium. i've heard of people passing out by inhaling balloons so i thought it was decent enough at least.
sorry you got unlucky, hope it works out for ya

They say right on those tanks and in all the online sales information that those are 80/20 or something like that. There are places that sell 99% helium but I don't know if just anyone can go buy one, also they are more expensive.
