Placing drinks in iced salt water is an effective way to cool them down but this is made even faster using a Beer Can Spinner.
It has environmental benefits as it reuses the packaging the beer cans came in (clip-on top).
An aluminum beverage can, rotated in icy water with a Beer Can Spinner will be cooled to 5 c in less than 5 minutes.
Supplies
Clip-on top packaging
Roofing bolt and nut
Sheet of grade 240 sandpaper
Clip on Pack

Place the plastic disk on top of a sheet of 240 grit wet and dry sandpaper and draw a circle around the circumstance.
Cut out the disk of sandpaper.
Trim the disk so it will just fit into the underside of the clip-on disk and remain there.
The sandpaper is to give move grip to the aluminium can.

The beverage can was spun in the icey salt water for 3 minutes. This cooled the drink down to 4 degrees C.
When another can was tried, it could only be cooled to down to 10 degrees C as the salt water had warmed up from the heat transfer from the cans.
