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?
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.
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
This is an excellent question. However you must realize that every house that’s ever been built has holes everywhere in it. There are vents in the attic, air can come in under the doors, air can come in even through the cracks behind and near the windows. So no house is ever really totally airtight, so it cannot block the air pressure from above. The only way to do something like that is to build a completely sealed house that’s absolutely completely sealed, and then you would have to pump out all of the air that’s inside only then would you have zero air pressure inside. Real houses can never have zero pressure inside, because there are holes everywhere the air can get in. Excellent question!
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
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!
Your explaining is perfect. Loved it👍
Not because of the air pressure ..but because there is no room for the air to come inside.
Fabulous expriment with Fabulous explanation
Very good
Use 2
Atmospheric pressure for energy generation

So he’s pulling air into the cup.
This is so cool
How high can the water from heron fountain goes up to?

Inspiring young ones thank you

@@MathAndScience thank u sir for ur effort in answering my question the explanation very clear so how much pressure in our house
Should be equilibrium
Nice
Noone could say the magnitude of air pressure inside a inverted half filled water bottle sealed at the bottom.can any one?
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!
Very Helpful 👌

WILL YOU BE KIND ENOUGH TO GIVE ME A SHOUTOUT???

LOL FIRST😂😂😂
Thank you! Hope you liked it.
