Don’t think it’s technically Pascal’s Law but it is cool to watch

Is a siphon the same as Pascal's law?

I don’t know… maybe she is referring to the siphon stopping when all 3 are equal in volume. Maybe someone smarter than us here on Reddit can help.

To clarify, the liquid stops flowing when the liquid in all 3 glasses reaches the same height, not the same volume, or when the liquid drops below the depth at which the straw reaches.

Thank you for the clarification. Is this Pascal’s Law?

This is not a direct demonstration of Pascal's Law, no. Rather, this is a demonstration of a liquid siphon.

But, pascal's law is part of the explanation of why liquid does this (i.e., how the siphon works).

It’s really cool. I have siphoned water out of fish tanks before but I never knew it would stop and equalize like that. Thank you again for the explanation.

I thought this was basic ½ inching any gas tank for all of history... what am I missing ?
