The weight of the ball is irrelevant if you have just enough pressure to lift it. When you add MORE weight to the marble ball, you will get the spray effect.
From what I understand, the water would spray out if it could, but there’s not enough room, so the force instead pushes the ball up to give more room, but the engineer tailored the forces just right so that once the ball is lifted, the force that would have made the water spray out is already used up, so it doesn’t spray. There’s only enough force to spray or lift, not both.
Imagine a trickle of water. A heavy marble ball might construct it and force it to spray out, but a foam ball of the same size would not be heavy enough, and the water would push it up and out of the way.
So if your marble ball is forcing the water to spray out, increase the flow of water from a trickle up to whatever it needs to be for the water to lift the marble instead of spraying out.
Now take a marble slight bigger than the end of a hose and hold it tightly
I don’t see how the heavy granite balls don’t do the same
The giant granite ball is not being held tightly. For your example just set the marble atop the opening of your hose. The water will continue to slowly overflow the end of the hose. Now if you exert additional force on the marble that’s on you.
You should do this yourself and take a video. Share it and speculate with us why the objects in your video behave the way they do.
If you tried it with a bunch of different weights and sizes im sure you could get the same effect eventually.
An any hose and an any marble, not likely. This is a precision feat of engineering, with minds sharper than ours dedicated to the study and application of these forces.
If any monkey could do it then it wouldn’t be impressive.
But that’s why I’m askingbwhy the heavy marble ball doesn’t force the water to spray out.
A light foam Ball would be like you described.
A heavy marble or granite ball will constrict the water forcing it out under pressure
This is “1kg of feathers vs 1kg of stone”

(Is that right?)
Take your hose
Just barely turn it on.
Hold it up at eye level. The water fills the ending and slowly overflows the hose nozzle
Now take a marble slight bigger than the end of a hose and hold it tightly…water pressure will build and water will squirt out under pressure.

You can make a small model of this yourself using a marble and a dribbling hose. Try it.
