So our trees make our humidity…to some extent anyway.

Cool stuff, Richard. I requested an article from one of those authors quite recently.

Thanks,

Dax

Yah, we ‘get it’ with a gas, don’t think of it as a ‘vacuum’ in a solid, and (most of us) never really think about the concept related to liquids. I dismissed the extreme liquid vacuum concept because of something called ‘cavitation’ which is when a gas seems to appear out of nowhere and then disappear again within a body of water in response to a low-pressure-producing action within the water…happens all the time. I would like to have seen that addressed in the vid. Still, though; cool vid, Dax.

I should add that the bubbles result from the container/bottle of water being tapped on top with a rubber mallet. The second occurrence of bubbles leads to cracks forming in the glass. Tapping on the bottle neck will blow out the bottle bottom because of the cavitation shock.
