I know if you mix salt, ice, and water you can make a warm beer ice cold in like 2 minutes tops.
Throw some ice, water and salt in a cooler and drop in your 6 pack and your drinking in 2-3 minutes instead of the 10+ in just regular ice water or ice by itself.
Obviously works for soda as well just not nearly as fun.
I will need to conduct research. Please send me a cooler full of beer, ice, and some salt. My two cents
