Stop in for a cup of coffee

My 2 favorite stupid questions of the day after I explained the manufacturing process and cycle...

“So how come the gas cylinders with 2500 lbs of Helium can be changed out by a single operator? How can he even move something that heavy?”

I explained that the 2500 lbs was the gas pressure in the cylinder, not the weight of it. They still looked confused. Then I explained that the cylinder contains several hundred cubic feet of normal pressure Helium compressed into the cylinder to a total pressure of 2500 lbs so we get lots of it contained in a small space. Any other questions?

“Ok, but if there is that much Helium in the tank, why doesn’t it just float away like a blimp?”

OMFG...:BangHead:
