Unnecessary Invention of the Day

Here's the product description for the Glass Tank:

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.

The promises assured in that third sentence set the bar high for this $419 piece of funky glassware. Additionally, isn't there a certain level of satisfaction found in tipping over a wine bottle for that last drop? Either way, bottoms up!
