Calm Barrel / Improved mineral water bucket

Calm Barrel
Calm Barrel

As we all experienced, water in the barrel of fountain often bubbles after we fetching water, which sometimes makes us feel unpleased. Calm barrel can solve this problem by adding a sheet rubber near the bottom of the barrel. Of course, the sheet rubber will also keep the water from getting out of the barrel.

when the barrel stands on its head over the fountain, the air pressure outside will push the sheet rubber open until the pressure on both sides get equal. Therefore there will not emerge any air bubble with unpleasant bubbling in the barrel water.
