The Cold, Hard Facts
How does ice make drinks cold? We all know that ice is cold to touch. As you touch a finger to a piece of ice, your finger feels cold. It’s almost as though the cold from the ice is creeping into your finger. But, in actuality, it’s the other way around. Heat from your finger goes out into the ice, melts a little of the ice and turns it to water. You can feel the water on your finger.
The same reaction happens when ice is put in juice or a drink. The ice takes some of the heat from the drink. As it takes the heat away, the ice turns into water. The piece of ice gets smaller and smaller and the juice gets cooler and cooler. Ice cools all kind of things by taking the heat out of them.
