If you love drinking wine, but hate having to constantly refill your glass, Kouichi Okamoto’s Glass Tank is your answer.
The device consists of a bulb shaped container with the glass below. When the amount in the glass decreases, a constant amount is poured from the tank into the glass.
The wine will never overflow because of the balance between air pressure and water pressure.
Made of heat-resistant glass.
Measures 5.2″W x 3.2″D x 8.7″H.
