Thread: a HEAT ABSORBING MATERIAL

I would like to find a material that can absorb heat from a bottle of water.
And basically make the water chill around 3-4 degrees from the room temperature.(25C)
I know water has a very high specific heat capacity so lots of energy needed to be absorbed to increase its temperature by 1 degree Celsius.
I just want to make a bottle and surrounded by this type of material or liquid that absorb heat from the content of the bottle( let say the content has in general the same specific heat capacity as water), and make the content chill and ready to serve.
This is for my Ideas challenge, if you guys have any ideas or know any chemicals that have this physical property
Please tell me. I would be more than delight.
Cheers

You could use the evaporation process and simply place a wet sock over the bottle and allow dry air to pass over it. This has worked well for me in the past.
