The house pressure is between 50 and 100psi. Pounds per square inch. So now figure out how many pounds your ball weighs. Then divide that number by the pressure you have. This gives you the area you need. Make it slightly larger by 10%. Then figure out the radius of the circle you need to make that area. Cut that circle into the bottom part. Super easy, you just need a CNC grinding machine. Now take the ball that was also made by the CNC magic machine and lif it over the hole. You’ll need like a hundred buddies for that. Apply the pressure to the water and viola! The sphere floats! But as it floats, the water escapes thru the sides so it can’t fly away, it can only float. To make the water come out at some crazy pressure just make the circle a little smaller and increase your pressure. The smaller the circle, the more pressure you’ll need. It’s totally possible to have a ball that floats and sprays everyone around. You just have to overcome the boundary layer pressure. The speed of any liquid near a wall is 0. So the liquid right next to the wall is what can move. This motion crates a boundary layer where the speed of the liquid goes from 0 at the wall to some larger amount. A small gap means you’ll never hit the full speed of your pump. A big gap means your pump can develop a full speed flow. So in short, big pump, small ball, big circle ⭕🔴 will get you a flying ball that splashes everyone and a big electric and water bill.
