How to cool a drink without ice - Do it yourself DiY

How to cool a drink without ice ?

Don't you have enough of tepid drinks ?

Here is a trick to get it cold again.

All you need is a wet cloth.

Wrap up your drink like this.

It works with wet kitchen paper too.

Then you can leave it in full sunlight.

More the ambient air will be dry and hot, more effective it'll be.

How does it works ?

Its thermodynamics.

Sunbeams cause the evaporation of the cloth's water.

The water take off the heat of the cloth which chills.

The drink inside then cools off.

The wind speeds up the process.

This trick also works with glass bottles and cans.
