Milk Science Experiments for Kids

Make ice cream from milk

Did you know you can make homemade ice cream in a bag in less than 10 minutes with just milk, salt and ice? You don’t even need a freezer!! Add your own flavourings, make a delicious snack and learn about the freezing power of ice and salt at the same time.

Glue from milk

All you need to make glue from milk is milk, white vinegar and baking soda. The vinegar is used to split milk into curds and whey. This fun kitchen science experiment is very simple but requires adult help to heat the milk.

I wouldn’t use the milk glue for anything important, but it’s fun to make the glue and then set up an investigation to test how strong it is.

Make butter from cream

Did you know you can make butter from cream? This is a super simple way to make butter at home, but it does require a bit of effort. You’ll need good quality double cream, a jar and some very strong arms for this fun kitchen hack!

Create an ornament from milk

This activity also involves using vinegar to split milk into curds and whey. You can then squash the curds and make a small ornament! This activity is sometimes called making plastic milk.

Colourful magic milk explosions

You’ll need whole milk, food colouring and a little dish soap to create these fantastic milky colour explosions. Older children can use this activity to learn about emulsions, too!
