Everyone are known the problem when you place a beverages in the fridge to cool it up but really don't want to pick it out because of the drink inside is still fairly warm even in 20 minutes later. I propose the temperature sensor. Put it on the bottle or glass filled of drink and in a minute it's already cold. It would work like the modern batteries which have a power sensor built in and send waves like microwave oven does, but our device should has opposite functionality. It should refrigerate the beverage so you could drink it in one or two minutes after the device was applied. I guess all of you who like pepsi, beer and other beverages quenched will support my idea.
