Method Exit bag method question

[starcharms]

Hello everyone,

Can anyone please tell me where I can buy single cylinders of nitrogen gas?
There are places near me that sell them in bulk for industrial purchases but I can't seem to find anywhere that sells single cylinders.
I have heard welding supply stores might? Is that true?

This is of course for the exit bag method

Thanks

Welding supplies store definitely do. I'm looking for an online shipping if there are any. I tried argon and it did not work. Helium has a shortage so the best bet is nitrogen
