Beat the Heat: How to Make Your Own Ice Cream!

Looking for something to do with the family, inside, on a hot summer day? If so, KY Forward's “Science Guy” Jason Lindsey shows us how to use a few ingredients from around the house to create homemade ice cream.

Homemade Ice Cream

Ingredients:

  • Half cup of Half & Half
  • 1 tablespoon of sugar
  • 1 tablespoon of vanilla
  • 1 sandwich bag
  • 1 gallon bag
  • 3 cups of crushed ice
  • Third of a cup of rock salt

Instructions:

Step 1: Place the Half & Half, sugar, and vanilla into the sandwich bag and seal it

Step 2: Place the ice and rock salt into the gallon bag, then add the sandwich bag into the gallon bag, then seal the gallon bag

Step 3: Squeeze the gallon bag until the ice cream thickens

Step 4: Remove the sandwich bag from the gallon bag, open the sandwich bag, and using a spoon, taste your homemade ice cream!

Explanation:

The salt lowers the freezing point of the ice and creates a cold brine which absorbs the hear from the bag containing the Half & Half, sugar, and vanilla. This causes the contents in the bag containing the Half & Half, sugar, and vanilla to go from a liquid to a solid, creating homemade ice cream!
