The visceral and parietal pleura are what keeps your thoracic cavity airtight. If the pressure gradient between the outside of your chest and the pleural space that your lungs occupy were compromised, via puncture wound or pneumothorax, then your lungs would crumple up like like a deflated balloon. The parenchyma (part of the lung you’re referring to) is spongy, but it won’t hold any air if it doesn’t have that pressure gradient to keep air in it. It takes very little to compromise that gradent. Two puncture wounds on each side of the chest would be enough
Yeah thats not how it should work, if we puncture a live person their lungs are gonna collapse, the same thing probably happens if we were to do it after they died. See what happens in pneumothorax? Lungs shrink (lack of negative thorax pressure) and trying to breathe pulls air through the hole in your chest instead of to your lungs.
They might not float immediately, but don’t decomposition gases eventually make them float?
Also the lungs are not simply bags filled with air. They are kinda like a sponge. Puncturing a sponge won’t do fuck all.
Yeah but a sponge in an airtight bag vs a sponge by itself will
But is isn’t like a normal sponge, it’s a sponge made of bags. If you puncture some part of it the other parts will stay dry

I assume they mean the GF is referring to puncturing the pleural lining to give the corpse a collapsed lung.

Puncture everything!
