The Glass Tank Wine Glass is shaped like a balloon to perfectly aerate a bottle of red wine as you drink it. The glass tank allows one to pour an entire bottle of red wine into the balloon-shaped cup, so you never have to refill your glass. Created by Kouichi Okamoto, this aesthetically pleasing wine glass makes a great addition to any wine curator's cabinet.

The device consists of a bulb-shaped container with the drinking glass below. When the amount in the drinking glass decreases, a constant amount is poured from the tank into the glass. Kouichi Okamoto says, "The wine will never overflow because of the balance between air pressure and water pressure."
