    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.

    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.
