In this video I show you how capillaries can decrease the pressure in a liquid well below an absolute vacuum if they are small enough

I have a feeling that he's slowly revealing his superpowers...

i think its surface tension, not pressure

If I were to be serious for once, I just wanted to say that your video ideas are always creative and fascinating.

am I the only one who feels like he repeats himself on every point like 5 times

The flat earthers should watch this, just so that they can see that water finds separate levels.

Finally, to understand capillary better than just theory from our SCHOOL teachers

Anybody else began to feel the negative pressure

Just know that unfortunately, a straw cannot be longer than 30 feet. My dreams have been killed.

I must say that lower pressure sucks.

well, the meniscus are formed due to the adhesion forces and the surfacw tension of the liquid, which it was mentioned in the later part

Have you tried filling it until the capillary tube overflows but attaching another tube that feeds the overflow back into the large fill chamber. Would that cause a constant motion of it flowing into the fill chamber as it is pulled through the overflow tube via gravity and vaccum and capillary action forces all working in unison?

If you kept pouring it would the small tube overflow? If so could you run it back into the big tube and have a perpetual machine?

I think Veratasium made a video for trees and negative pressure. Very cool.

He really should start another channel where he teaches actually interesting chemistry and/or physics classes for high school students

Pressure is an emergent phenomena where molecules randomly colliding into one another at a microscopic scale. The natural question to ask is, what's going on at the microscopic scale for the negative pressure?
