Suppose you were shooting a 3D stereoptic movie for a classroom
setting, would it be sufficient to put a few drops of milk on a
vinyl record, spin it a little bit on a phonograph player, and
then ray-trace it up and down so that it has the appearance of
depth and height? Would that be suitable for your basic hydrogen
atom? Using the same setup, would two drops work for a helium atom?
