Humanity can’t yet get to Mars, make the subways run on time, or get rid of the penny, but we have at least figured out how to pour wine without turning the bottle upside down, and that counts for something.

The Waerator is a battery-powered gadget that basically acts as a tap for any bottle of wine. Just shove the contraption down over the mouth of the bottle, and hit the button to dispense wine. On the way up, it’ll also get heavily aerated (they claim six times more than a gravity-fed aerator), which really can improve the flavor of certain varieties of wine.

The Waerator almost always sells for $60, but today only, Amazon’s knocking that down to $40. Even if you don’t want it for yourself, this could make for a good gift later down the road.
