How to keep the drinks cold without fridge or ice or icebox.

Ans: BLANKETS.

One day i was really craving some beer but room ma lyayesi by the time I'm reaching the fourth bottle, it's not as chilled anymore...and similar with bringing those lil coke zero i usually get 3 at once, I used to use thermos for coke so i can enjoy for longer and don't have to rush for the chilled drink..

But then all the thermodynamic or kinetics knowledge kicked in and i thought, IF BLANKETS that are Insulators can insulate by body heat that also means they're insulating the Outer cold and Bam! I tried it with beer, coke and it worked... And i am happy.

Just wrap it well
