Claim:
A water aerator, comprising: an aerator frame, wherein the aerator frame has an upper portion and a lower portion opposite the upper portion; a pressurized gas container disposed beneath the frame; a gas-dispensing nozzle disposed beneath the flame, the nozzle communicating pneumatically with the pressurized gas container; a float disposed generally medially within the frame; and an inner gas supply tube and an outer gas supply tube coaxially disposed around the inner gas supply tube, the gas supply tubes extending through the upper and lower portions of the frame, the inner gas supply tube having a lower end connected to the pressurized gas container and defining a high pressure gas supply, the outer gas supply tube having a lower end and defining a low pressure gas supply tube, the nozzle being attached to the lower end of the outer gas supply tube and disposed concentrically around the inner gas supply tube between the lower portion of the frame and the pressurized gas container, the inner and outer gas supply tubes defining a conduit for the flow of pressurized gas from the gas container up through the inner gas supply tube to above the upper portion of the frame and down through the outer gas supply tube and out through the nozzle below the lower portion of the frame.
