WHAT’S HAPPENING:

This experiment works because of the ice used. To make the ice cream, you need to lower the freezing point of the ice so it can freeze the cream. Have you ever seen trucks spreading salt during an icy snowstorm?  Salt causes the ice on the roads and sidewalks to melt. When salt and ice mix, the freezing point of the ice is lowered. And so, ice cream in a bag can be made!
