The weather is warming up. Make some tasty ice cream using science and a couple of common grocery items!
What's Going On?
The salt is the key ingredient here. Although you don't want salt inside your ice cream, it is crucial that it's outside it in this project! The salt, when mixed with the ice in the gallon bag, made the temperature of the outside much colder than what it would have been with just the ice. This decrease in temperature is what allowed the liquid mixture in the quart bag to turn into solid ice cream. Try the experiment again with different variations! You can substitute the heavy cream for another type of milk, or add less or no ice to see what happens.
