Comment on This has been your weekend PSA

Thanks for the answer! That’s pretty cool honestly! Could you achieve the same result with anything that spins, like a lettuce spinner?

You just need a way to spin the can. Probably works better if you speed it up and slow it down or reverse direction.

  I think a lettuce spinner would probably work, since it has a basket inside a container. I might give it a go next time I buy a can of anything

The main reason spinning a can works is because it induces convection inside and outside of the can, which contributes to more collisions and better distributions of collisions. If the warmest soda is in the middle of the can, the cold molecules near the can walls will reach a temperature similar to the ice bath and thud the rate at which heat is transferred becomes stunted.

For lettuce, you’d have better luck finding a way to pass cold water between the leaves, much like having fins on a heatsink (surface area).

  No, a lettuce spinner is a little basket inside of a container with a handle that you can spin to turn the basket. You wash your lettuce and put it into the basket and turn the handle. The centrifugal force (I think) causes the water clinging to the outside of the lettuce to drain into the container.
  
  I think if you filled the container and basket partially up with ice or crushed ice) and some water, it’d achieve the same result as the machine someone linked above

    Lol… I have never heard of this before. I think it would help halfway, but it won’t induce much stirring inside of the can, which is more important than just throwing more cold molecules of water at it.

Just use your hand. If the beer is in a bottle, leave it so the neck is sticking out of the ice water and spin it that way (this also works very well for wine.) If it’s a can, stick it in vertically, and spin it for 30 seconds at a time or whatever you can stand.

Even if you aren’t constantly spinning it, it will still get cold much faster than any other method. I’ve worked in bars and restaurants for 15 years, and this is my go to, in case of emergency method for chilling beverages.
