What is inside cooler shock ice packs?

Cooler shock ice packs are, like many other similar products on the market, dry ice packs. So the ice packs consist of a gel-like material known as PCM, or Phase Change Material. While water will freeze and turn into ice at 32 degrees Fahrenheit, PCM will freeze at 18 degrees Fahrenheit, making it much colder than ice.

How do you make a long lasting ice pack?

What material would make the most efficient cold pack?

You can make a basic cold pack by mixing a salt (such as potassium chloride) or soda (such as baking soda) with water. Mixing the two creates a chemical reaction that uses up energy, which makes the mixture colder.

Does adding salt to ice make it colder?
