Homemade Ice Cream - BY ABBY

I made ice cream yesterday with my friend Atticus. We used salt, sugar, vanilla, ice and milk. We used 1 gallon size ziploc bag to put in the ice and salt (make sure you don't get the salt in the little bag). We put sugar, vanilla and milk in a sandwich size ziploc bag. We put the little bag inside of the other bag and shook it up for 5 whole minutes. After we were done we ate it. We compared what we made to the ingredients in whip cream and the ingredients in factory made ice cream. We discovered that the factory made ice cream and the whip cream are not as healthy as the stuff we made, but I like the factory made ice cream better because I got salt in my bag and that tasted yuck! Here is the recipe if you want to try it:

Put the following ingredients into a sandwich size ziplok bag and seal (you can double bag this to prevent the salt from getting in)
1 tbsp sugar
1/2 cup milk
1/2 tsp vanilla

Fill gallon size ziploc half full with ice and add 6 tbsp rock or regular salt

Put small bag inside of large bag and shake for 5 minutes and it will turn into ice cream!


AN UPDATE -

We wanted to find out if you could make this recipe without using the salt so we tried it. The ice cream doesn't freeze if you just use ice. We looked it up online to find out what the salt did to make the milk turn into ice cream. Ice cubes just freeze something to about the point of water freezing (32 degrees) and in order for ice cream to freeze it has to be cooled to 27 degrees. Once you add the salt to ice it makes the ice colder and lowers the temperature that it melts at to about -5 degrees, making it plenty cold enough to freeze the ice cream mix.
