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.








This still works in the US too but… And it’s a big BUT! …but it entirely depends on the cop, the mood they’re in, and how their sex life is going. I’ve had times where I’ve been high as a kite and been given a warning or been driving 20 mph over the speed limit and got a warning.
I’ve also been on a bike and nearly hit by an off-duty cop, the cop was angered by this and chased me down the highway at bike speed (<15mph, uphill) while the road is posted to be 50mph. I called the police, fearing for my life, and when police arrived I spoke with them and they said I had nothing to great from this engaged motorist because they were also a cop. Then I was given an indictment (a court date) for public disturbance because the cop lied and said I, a trans person, called him the F slur. It was dismissed in the end (first amendment rights and all that) but I was punished for riding my bike along the bike path by being legally ordered to go to court and explain that I was terrified and had shouted at the crazy out of control person chasing me: “If you follow me I’m calling the cops!” The cop had no repercussions!
Anyway, my point is, you can get lucky either way but when your luck turns they hold all the cards and your only rights become what they decide you get.
