Making Homemade Ice Cream in a Bag: A Fun Science Experiment

What is the purpose of adding salt to the ice when making homemade ice cream in a bag?

The purpose of adding salt to the ice when making homemade ice cream in a bag is to lower the melting point of the ice. This allows the ice to absorb heat from the surroundings, including the cream mixture inside the bag, which causes the mixture to freeze and turn into ice cream.

When making homemade ice cream in a bag, adding salt to the ice is a crucial step in the process. The salt lowers the melting point of the ice, causing it to absorb heat from its surroundings. This process, known as endothermic reaction, helps reduce the temperature of the cream mixture inside the bag. As a result, the mixture freezes and transforms into delicious ice cream.

Without the salt, the ice would not be able to absorb enough heat to freeze the cream mixture efficiently. This is why salt is an essential ingredient in making homemade ice cream in a bag.
