Looks very entertaining, :clap: but being the cynical old bastard that I am, I have two observations.
1/ There appears to always be water in the bottom of the cups, presumably to absorb the energy of the falling ball and stop it bouncing out of the cup.
2/ Taking it that there is water in the cups, why don’t we ever see any splashing up or out of the cup when the ball presumably falls into it ? :?:
I used to be a killjoy, but now I’m just cynical.
