    Wait, it’s just the stuff they use at the dentist?

    Now I’m confused, I didn’t think you could buy those in tanks or charges I thought it was always carbon dioxide

      Yep, it’s nitrous oxide. It can be purchased in 3 grades. Medical grade requires some kind of licensing, food grade does not. Don’t inhale industrial grade nitrous.
