Quite a story, thanks for posting. I had no idea nitrous oxide could do this.
I worked in an ice cream store back in the day, and one of my co-workers was always huffing the gas out of the whipped cream cans. If you don’t shake it, the gas is all at the top. But then the contents come out as just mush, not “whipped”. This was annoying! Especially as we were required to charge an extra 10 cents for whipped cream!
As to the two dopes in this story, the nitrous clearly isn’t working for them. If they can’t stay sober, my advice is to start drinking beer and smoking cigarettes immediately. Stick to organics, people, eschew chemical intoxicants.
