A float floating in a liquid has a spherical body having a spherical shape from which parts are cut off so as to form a regular hexagonal shape when viewed from one direction. In addition, the float is shaped so as to form a regular hexagonal shape when viewed from the above-mentioned one direction, and the floats are arranged in a honeycomb geometry to thereby reduce the contact area between the liquid and air.
