Under the insulation barrel, place a self-contained cooling water unit (see photo). This device can be used to lower the temperature of a number of non-toxic thin plastic hose into the plate. Hot water flows in from the upper end of the hose and cool water flows out from the lower end of the hose. Cooling tap water flows in from the bottom of the unit and out of the elbows 2 with the top down. Put appropriate amount of cool drink in the thermal insulation bucket and pour into hot water.
