摘要： A medium having a dew point close to the freezing point of the surrounding water is enclosed in a watertight collapsible hollow body anchored to the bottom. The collapsible body, which normally floats at the surface of the surrounding water, sinks when the freezing point of the water is approached due to the condensation of the medium. The hollow body remains submerged in a collapsed state until the water warms, vaporizing the medium and causing the body to float again.
