MOTORIZED PAPER FISH PATTERN Carefully place the paper fish on the surface of the water in the bowl. Place a drop of oil or detergent in the hole in the center of the fish. The detergent or oil will lower the surface tension of the water in this hole. In a few seconds, the fish will begin to move across the water, propelled by the oil or detergent. The oil or detergent will slowly begin to spread out across the surface of the water in a thin film. Its flow is powerful enough to act as a jet and propel the fish across the water without its being touched or pushed.
