Have you ever tried this awesome edible ice cream science experiment? Whether you make it inside or outside, make sure you have a pair of warm gloves ready. This homemade ice cream in a bag recipe is chilly chemistry for kids you can eat! Enjoy fun science experiments all year round!
HOW TO MAKE ICE CREAM IN A BAG
MAKING ICE CREAM
Making homemade ice cream is actually quite easy and a good workout for the arms! This ice cream in a bag science experiment is a fun activity to try at home or in the classroom. It does require some adult supervision and assistance. A good pair of gloves are needed as this science activity does get very cold.
Edible science has become one of our favorite things to do together these days. Possibly because I have a kiddo going into third grade and growing like a weed. Whenever I mention anything about food, eating, edible science… He’s all in. BIG TIME!
It’s summer, and we love ice cream. Instead of heading to the local dairy bar, grab a few simple ingredients and head outdoors. Kids can learn just how their ice cream is made… with chemistry!

ICE CREAM SCIENCE
What’s the chemistry behind ice cream because it’s pretty sweet!
The magic is in the salt and ice mixture in the bag! In order to make your homemade ice cream, your ingredients need to get very cold and actually freeze. Instead of placing the ingredients for ice cream in the freezer, you mix together salt and ice to make a solution.
Adding salt to the ice lowers the temperature at which water freezes. You will actually notice your ice melting as your ice cream ingredients start to freeze.
Shaking the bag allows the warm cream mixture to move around to allow for better freezing. Plus it also creates a little air that makes the ice cream a bit fluffier.
Is ice cream a liquid or a solid? Homemade ice cream changes states of matter. Also more chemistry! It starts out as a liquid but changes to a solid in it’s frozen form, but it can go back to a liquid when it melts. This is a good example of reversible change as it’s not permanent.
You will definitely notice that the bag becomes much too cold to handle without gloves, so please make sure you have a good pair of gloves to shake it with. Read on to find out how to make ice cream in a bag!
ICE CREAM IN A BAG RECIPE
- 1/2 cup half and half (cream and milk)
- ¼ tsp vanilla
- 1 TBSP sugar
- 3 cups ice
- ⅓ cup kosher or rock salt
- Gallon size zip top bag(s)
- Quart size zip top bag(s)
- Sprinkles, chocolate sauce, fruit (optional but really “the best part” ingredients!)
HOW TO MAKE ICE CREAM IN A BAG
STEP 1. Place the ice and salt in a gallon size bag; set aside.
STEP 2. In a smaller bag mix together half and half, vanilla and sugar. Make sure to seal the bag tightly.
STEP 3. Place the smaller bag inside the gallon size bag. Shake the bags for about 5 minutes until your milk is solid.
Make sure to use gloves as the bag gets very cold.
Time to enjoy your yummy homemade ice cream!
TURN IT INTO AN ICE CREAM SCIENCE PROJECT
If you would like to take this your homemade ice cream in a bag recipe and turn it into a science experiment, try these suggestions:
- What happens if you don’t use salt? Set up two bags for making ice cream but leave the salt out of one bag.
- What happens if you use a different type of salt? Set up two or more bags for making ice cream and choose different types of salt to test!
- What happens if you swap out the milk for the heavy cream? Or what happens if you try another type of milk like almond milk. Set up two or more bags for making ice cream and choose different types of milk to test!
