Summer Science: Homemade Ice Cream
Students from ECCA demonstrate how to use chemistry to make ice cream
EFFINGHAM COUNTY, Ga. (WTOC) - Effingham College and Career Academy students Sean Mahoney and Austyn Zerangue walk us through the steps to create vanilla ice cream using physical chemistry & items you can find around your home.
MATERIALS:
- Measuring spoons/cups
- Sugar
- Milk, heavy cream, or half-and-half
- Vanilla Extract
- Salt (Table or rock)
- Ice cubes
- 1 pint or sandwich sized Ziploc bags
- 1 Gallon-sized freezer bag
- Oven mitts or small towel
- Timer or clock
STEP ONE
- Inside small Ziploc bag place:
- One tablespoon of sugar
- 1/2 cup of milk, heavy whipping cream or half-and-half
- 1/4 teaspoon of vanilla extract
- Seal the bag well
STEP TWO
- Inside Gallon-sized Ziploc bag place
- 4 cups of ice cubes
- 1/2 cup of salt
- Take small bag and place it inside the large bag with ice
- Seal both bags shut
STEP THREE
- Take over mitts (or wrap bag in towel) and shake the bag for 5 minutes
- Feel the small bag every few minutes while you shake it until it feels close to the consistency of ice cream
STEP FOUR
- EAT!
This demo allows you to witness physical chemistry in real time.
The salt lowers the freezing point of the ice, thus creating the ice cream.
