Glass Tank by Kouichi Okamoto
Updated: Jan 29, 2020
Kouichi Okamoto, founder of Kyouei design, designed a very innovative device called Glass Tank that combines a bulb shaped vessel with a heat-resistance wine glass to both store and drink in and from it. As the amount in the drinking glass decreases, a controlled amount is poured from the vessel refilling the glass. The liquid never overflows due to the air and water pressure.
