I need somebody to explain this to me. When i have a plastic bag over my head taped around my neck with a cord pumping helium inside, doesnt the bag just expand like a baloon and pop after a while? Or do i leave the valve turned off?
Bonus question: is a 2.2 liter tank enough?

I think you need to turc the valve off before thé helium pump inside the bag. It should work, maybe for something that you dont want but for something good for you.
go on youtube and type in “doing it with debbie”. She gives a brief instruction on how the exit bag works.
