In this video I go into the physics of my spinning water demo.
I derive the exact curve of the water surface using simple high school physics and math.
It turns out that the shape is a parabola! more specifically it's a paraboloid, but my thin tank only shows a cross section of it.
I use the derived curve to estimate how fast the tank spins. I was able to verify the obtained value by directly measuring the RPM, and it seems that everything holds up :)
