Three clear plastic glasses are stacked, one on top of the other in a vertical column. Liquid of one color is poured into the uppermost glass, almost to the top. Performer then pours a liquid of another color into uppermost glass. Magically liquid magically flows into the middle glass of the stack. Finally a third different colored liquid is poured into the top glass and mysteriously penetrates to the lowest glass.
Glasses are separated and each is shown to be filled with its own colored liquid.
A mechanical trick, made possible with the very specially constructed clear plastic glasses that are supplied.
Also comes with extra gimmick.
