Three clear transparent glasses are stacked one on top of the other. The performer displays three other glasses with three different colored liquids in them. He now pours liquid of one color into the top glass of the stack, almost to the top. Nothing magical so far. He then pours liquid of another color into the upper most glass. Instead of mixing with the liquid in the upper glass, the liquid magically flows into the middle glass of the stack. The effect is visual, and extremely mystifying. Finally liquid of the third color is poured into the upper most glass, and mysteriously penetrates into the lower most glass of the stack. The three glasses are separated, showing each containing the three different colored liquids. Liquid Penetration is a mechanical trick, made possible with the very specially constructed clear glasses supplied. This is a custom molded item using standard sized glasses, suitable for stage or platform use. We supply you the special glasses, the extra gimmick, the dyes that permit you to dye ordinary water for the different colored liquids, and full working instructions.
