youve got normal air pressure on the outside ( about 14.7 psi) and inside, then 6 psi above this on the inside ( guage pressure), so the net pressure is 6 psi, the force on the lid = area of lid in square inches * guage pressure
A 55 (us) gallon drum has a diameter of 22.5 inches, yielding a surface area of
400 sq. ins. multiply * 6 psi = 2400 lbs. force on the end plates
Try squeezing all of the air out of the bottle before screwing the lid on tight. It works well for me. It will stay fizzy until the last drop.

Open the air cleaner box lid, remove the old, put in the new, put the lid back.
Imagine the air surrounding the water is like a sponge. When the lid is closed, only the air in the jar acts like a sponge, so we have a very small sponge. When the lid is open, ideally all the surroundig air acts like a sponge, and that is very big.
What is required is force on the inside of the lid of the box that is greater than the force of air pressure on the outside of the lid.
in a ten or five gallon tank, you can use one of the lids especially made for those tanks. Those are the only cages hermit crabs can live in, so if you don't have a glass 10 gallon tank, get one! Make sure the lid has airholes
The hot air inside the can cooled after the lid was put on. Cooling air contracts, pulling the can's parts inward, causing the collase.
The air in the can could either pop the lid off or destroy the can as it got hot and expanded.
Sure. It's the air pressure, and it works like this; Get a gallon can with a lid and make sure it's clean and empty. Put about a half inch of water in the bottom and place the open can on a stove. Let the water boil for a minute, or so, to push the air out (replacing it with steam). Remove the can and after a few seconds (when the water has stopped boiling) put the lid on tightly. Watch the can for a few minutes and it will crumple as the steam condenses and forms a partial vacuum.
air is escaping. boiling veg in water causes air bubbles to be formed, which pressurize the lid up. Jimmy Neutron
Yes that is big enough but you will need a lid so it doesnt escape
