How Temperature Effects Air Pressure

STOP, STOP, the worktop... too late.
Oh no, fingers crossed the compressor does blow the bottle apart!
I wonder where the coke bottle going to go... phew that was lucky.
Do I just have a well developed imagination of consequences?

Haha. I thought it would be funny to "accidentally" stab the table with the drill. I once saw a nerdy tech talk show where they were eating greasy potato chips and typing on a keyboard. It was a bad joke I'm sure, and after I got over the horror of it all, I realized the humor in the scene.

Neat video; thanks danhor7. For those of us who aren't willing to cut up our footballs (and perhaps drill into our work tables 
):
Pyramid Air has them for sale. Should be a booming market for them.

Hahaha. Crap I thought I was onto something. The way they're coupling to the bottle doesn't rely on the cap threads to retain the pressure. I might have to make one of those. When I was a kid, we put some tin foil and (The Works) drain opener in a bottle and the bottle inflated like a balloon before it burst, and it was really loud. That's where I got the idea for this. Or thought I had an idea that is. lol.

I realized I made a pretty major technical mistake in the narrative, so I've made a feeble attempt to correct with a note during the f-up. I really need to reshoot the scene and figure out a way to illustrate/animate it accurately.

I think we might be confusing water vapor (stm.) vs. breathing air, Remember atmospheric psi is 14.7 psi @ sea level or 29.9in. Hg, and you can boil wtr. @ about 75 Deg.F. in a perfect vacuum, If I remember my chem. & Phys. right? This coment is referring to original post. I sure hope the breathing air from my scba tank does not contain any H2O

It doesn't matter. A gas is a gas. Heated, they expand. Cooled, they contract. Alternately, compress them they get hot, or evacuate them and they cool. Boyle's Law is pretty simple. Steam just provides a dramatic example because it contracts so very much when it is cooled that it actually creates a vacuum that will crush a can.

Right. When you compress a gas, the temperature rises which is why the pump and air cylinder warm up while pumping.

Also if you have a vessel with normal atmospheric gas/air in it and you warm it up the pressure will rise. I shouldn't have warmed the bottle over hot water. I see now that it was misleading. Also I messed up while explaining the thermal expansion process. The molecules or particles don't grow when warmed up. They just collide more energetically which causes them to "bounce" off of each other harder/farther and the space between them "grows".

That's how and why powder burner's and internal combustion engines work.
