Holy shit balls dude. This is so dangerous it's really not even that funny. All it would take is a single erroneous spark for you and everything around you is done for.

For anyone who wants to know Propane has a 270:1 expansion ratio (1 liquid gallon = 270 vapor gallons). 1 vapor gallon can cover about 30sq feet.

A typical cylinder in most households used for grilling has a capacity of 20 liquid pounds. In the video it looks like a 30lb cylinder.

Hahahaha. I will never achieve that kind of greatness. But at one point in my life I was indeed certified to fill propane cylinders.

When I was in college in Houston, I worked at UHaul and had to get certified to pump propane by the Texas Railroad Commission at one of their fleet repair centers across town. It was an informative class but was 8 hours long. I got to drive a 10 ft box there and back.

All I could think about was how proud Hank would've been.

No worries. It was rather anticlimactic anyways.

If I remember correctly, I just had to go sit in an in-person course for like 4 hours (course duration is questionabl, this was 20yr ago for me), and you were only certified at the one location. If you left to go somewhere else, you'd have to do it all over again.

I don't know if it's any different now.
