Then, place the bag inside the container with the salt and ice. 6. Next, shake the container and the ice cream will be ready in 17 minutes. 7. Finally, remove the bags from the jar and rinse them with water and enjoy! Lesson: Salt causes ice to melt. When salt comes in contact with ice, the freezing point is lowered. Heat must be absorbed by the ice to melt, which means the heat that causes the melting comes from its surroundings. By lowering the temperature at which ice is frozen, you are able to create an environment where the cream could freeze at a freezing temperature to make ice cream.
