Kiddos: Homemade Ice Cream in a Bag
Written by: Allison Swan
July is National Ice Cream Month! What better way to celebrate the most delicious month of the year than making your very own just like you did as a kid in science class. Everyone will be screaming for more after making this single-serve homemade ice cream that's made with a few basic ingredients and some shaking. Besides eating this treat, kids can help you make the ice cream and explore science as they see creamy liquid turn into a solid. Here's what you'll need:
1 1/2 cups half and half
1 tablespoon sugar
1/4 teaspoon vanilla
1/2 cup rock salt
3 cups ice
1 gallon-size zip lock bag
1 pint-size zip lock bag
1. Fill the gallon-sized zip lock bag with half the ice. Have your child sprinkle half the rock salt over the ice and then place the pint-size zip lock bag inside.
2. Carefully measure and pour the half and half into the small pint-size bag along with the vanilla and sugar. Make sure the top is tightly sealed.
3. Pack the rest of the ice around the cream-filled baggie and then sprinkle with the rest of the rock salt. Zip the top, wrap in the dish towel, and get ready to shake.
4. This is the perfect time to talk with your child about what role the salt plays in the experiment while they are shaking the bag. Without the salt, the ice wouldn't dip below 32°F, which isn't cold enough for making ice cream. The freezing point of salt water is lower than regular water, so adding all the salt is an essential part of making the cold treat.
5. Have your child keep track of the time and check the bag after one to two minutes of good shaking.
6. Once it’s creamy, remove the ice cream from the bag of salted ice and enjoy straight from the bag.
