Liquid covering disks

A disk configured to float on the surface of a body of liquid, comprising:

• a top portion including:
• a top interior surface,
• a top periphery all extending transversely from the top interior surface to a top periphery wall terminal end, the top periphery wall defining a top port and extending around the top interior surface to partially enclose a top cavity,
• a top chamber wall extending transversely from the top interior surface to a top chamber wall terminal end, the top chamber wall extending in a continuous path to partially enclose a top chamber;
• and
• a bottom portion including:
• a bottom interior surface facing the top interior surface,
• a bottom periphery wall extending transversely from the bottom interior surface to a bottom periphery wall terminal end, the bottom periphery wall defining a bottom port and extending around the bottom interior surface to partially enclose a bottom cavity,
• a bottom chamber wall extending transversely from the bottom interior surface to a bottom chamber wall terminal end, the bottom chamber wall extending in a continuous path to partially enclose a bottom chamber;
• wherein:
• the top periphery wall terminal end aligns with and is attached to the bottom periphery wall terminal end to define a cavity, and
• the top chamber all terminal end aligns with and is attached to the bottom chamber wall terminal end to define a chamber.

A disk configured to float on the surface of a body of liquid, comprising:

• a top member configured to float substantially above the surface of the body of liquid,
• a bottom member spaced from the top member and configured to float substantially below the surface of the body of liquid;
• a sidewall extending between the top member and the bottom member along the periphery of the top member and along the periphery of the bottom member, wherein the top member, the bottom member, and the sidewall collectively define a cavity;
• a chamber mounted within the cavity, the chamber enclosing a predetermined volume of a gas;
• and
• a port defined in the sidewall to allow liquid from the body of liquid to enter the cavity;
• wherein the predetermined volume of as enclosed in the chamber is selected to impart a buoyancy force sufficient to maintain the disk afloat on the body of liquid with the bottom member a predetermined depth below the surface of the body of liquid;
• wherein the chamber is mounted substantially at the center of the cavity;
• and
• wherein the cavity includes a groove defined in the lower member surrounding the chamber to distribute liquid around the chamber to facilitate leveling the disk on the surface of the liquid body.
