A floating insulating beverage container is comprised of a double walled beverage container which is adequately buoyant and balanced to remain upright in a body of water. The adequate buoyancy and balanced is achieved by the buoyant forces available from the annular cavity created by the double wall container configuration and the balance by the non-buoyant or ballasted bottom of the container. The double wall annular space and ballasted weight are determined to maintain the drink container upright in a body of water, without sinking when filled with beverage, and not capsizing when empty. The double wall configuration also provides insulation for the beverage due to the void between the inner and outer walls. |
