To move not only a material whose specific gravity is lighter than water but also a heavy material by sensitively reacting to the fine flow of air without putting a part in a water surface by forming a super water repellent film on the entire part or a part of a surface on a surface to be brought into contact with the water surface.

A super water repellent coating material 2 is applied by using an air gun coating machine to both surfaces of a film 1 made of aluminum whose thickness is 100 μm and area is 4 cm×5 cm, a cut 3 is made to it with scissors and it is worked by bending 4 and twisting 5. Thus, not only the material whose specific gravity is lighter than the water but also the heavy material can be floated on the water surface by surface tension caused by the action of the super water repellent film. Thus, resistance to the water is reduced and movement is made possible by sensitively reacting to the fine flow of the air.
