Salt lowers the freezing point of water.

This interesting feature of salt and ice and can be used for lots of fun and easy experiments.

Did you know you can make ice cream using milk, salt and ice?

This works because as the ice melts heat is absorbed from the surroundings ( the milk mixture ) making them freeze.

See our full instructions for making ice cream with ice and salt here.

This would also make a great taste investigation. Try adding different flavours to the milk and investigate to see whether a friend can guess what each flavour is. You could even add some strong flavours like chilli or garlic!
