>>10873460There isn’t a real seal. Image a plastic bag upper side hanging motionless in the container and lower side below in the water, would air now magically move downwards into the side of the bag that’s in the water? Nope, from the perspective of the air in the container there is no plastic bag (‘seal’).
Also the balls are extremely light so gravity of the balls on the right can be ignored.
For the pulling down of a ball into the water from the container for arguments sake we can time this exactly with a ball emerging from the water at the top, so those forces cancel each other out.
What’s left is an x number of submerged balls (or football shaped whatever) on the left pulling upwards and 1 ball being pulled through the ‘seal’ on the right.
Thank God for at least 1 high IQ anon
