Let's see. My logic says that the water is falling in sheets and the graphics are punched out, most likely with a computer built from transistors we provided in 1947. Since the water is all the same size in molecules (generally speaking) the bottom and top of the water fall -ing will fall at the same 132 feet per second per second. That computer punch has to be quick!!!
Does anyone really know how that is done?
Edited: Ah! Never Mind. I do my own research.

This is not the Japanese one, but I'll bet you it works on the same principle - water jets - fast ones.
