Air Pressure Vs. Water Pressure - Who Will Win? Science Experiment Teaches Pressure Balance.

Learn what happens when you balance air pressure against water pressure!

[salimabedalkhalik]

Not because of the air pressure ..but because there is no room for the air to come inside.

Are you actually blowing air into the cup? Isn’t that impossible because the cup is full? Isn’t this actually an example of Bernoulli’s principle of moving air pressure?

In other words, moving air has lower pressure. The fast moving air from the straw reduces the air pressure at the seam and lowers it enough to allow the water to escape. The escaping water is heavier than air falls and is replaced by air rising to the top of the glass.

Otherwise you could just blow and would not need the straw. But that doesn’t create fast enough air speed to reduce the air pressure. No?

Fabulous expriment with Fabulous explanation

[sebastianzelichowski]

Nice experiment 👍, the only thing is that the vacuum keeps the water from coming out not the air pressure around us, that's why air flows to the top to replace vacuum therefore when you remove cup quickly the water will fall quickly because it's so little vacuum that cannot hold the weight of water, over roll good experiment.

How high can the water from heron fountain goes up to?

[no-delg]

I have question if u are in ur home the atmosphere presure is zero because the roof of ur house blocking all the air vertically going downward direction ?? I don’t understand

[debajyotisaha]

Noone could say the magnitude of air pressure inside a inverted half filled water bottle sealed at the bottom.can any one?

[anilkumarsharma]

use a fifteen meter long box so we know how much water we found as a limit of atmospheric pressure

a fifteen meter cube above water surface so we got more pressure just below the water surface

Isn't there a little tiny air gap at the top of the second cup, which balances the airpressure outside?

Watching a grown man blow into a cup for a whole minute.



Best time of my life!

In every experiment to do with pressures, you need some sort of container! AGREE?
Yet we are supposed to believe that earths atmosphere gets thinner the higher you go, then simply meets the vacuum of space. Absolute fantasy!
