Chill-out and enjoy some cool and tasty kitchen science with CJ! Make your own delicious ice-cream with an understanding of how you can use an endothermic reaction to lower the freezing point of water.

To try at home you will need: 250 ml of cream; 250ml of milk, preferably whole milk (vegan alternative is coconut milk); sugar; salt; ice cubes; 2 x Ziploc bags (1 x large and 1 x small); some flavourings (e.g. vanilla and chocolate chips); a bowl; a jug; a spoon; and a bowl.

You will need some adult permission and supervision. The result will be a tasty treat to eat - especially on a hot, sunny day! Fun for all the family. View on YouTube.

N.B. This experiment uses milk and your chosen flavourings. Although rare, in some people these foodstuffs may cause an allergic reaction.
