My gadget today is a soda can (beverage) chiller.
Along with tea, I drink quite a bit of soda (i know, bad habit) -- which i drink out of standard 12oz cans. I usually have them refrigerated but sometimes not -- especially when guests arrived who want a flavor i don't keep in the fridge.
So this device can take a can from room temperature to very cold in only a few minutes. They do work.
The best known one seems to be this "Cooper Cooler" brand -- they make quite a few models and they also work to chill wine and beer bottles
That one above is about $60 -- you can get more expensive models and cheaper ones on ebay too.
The way this device works is that you fill up the container with ice, and it rapidly SPINS the can or bottle for a few minutes. By keeping the surface of the can/bottle exposed to ice while insuring the liquid inside circulates at the surface, the liquid inside is rapidly and evenly cooled.
Now, those models clearly look like the best performers, but I am a stickler for minimizing clutter and i didn't like the idea of having to fill this thing up with ice and plug it in, and store it, etc. And i didn't think I had much use for cooling bottles.
So instead I bought a super low tech cheapie version of this on ebay, called the Frost Boss, which can be found for about $20:http://www.amazon.co...s-1C3/dp/B008CQN3IA/
This one is battery powered and the spinning device is only a little larger than the size of a coffee mug.
So what I do with it is i threw away the container that you are supposed to fill with ice, and kept the coffee mug size spinner. I always keep a bag of ice in my freezer, so if i ever want to use this i simply take it out of cabinet, attach a can to it, turn it on, and place the pair in my freezer IN my bag of ice, close the freezer, and come back in 5 minutes to a cold can of soda. No muss no fuss, no cords no wasted cabinet space, no ice water to clean up.
