You’ll Need: 120ml milk 1 tbsp sugar A few drops of vanilla extract Ice cubes 6 tbsp salt 1 small zip-lock bag 1 large zip-lock bag Tried and Tested! I’ll admit, I never expect these science experiments to work, so I was pleasantly surprised when this one did! Our ice cream turned out a little milky, but it was edible (and rather nice). My 4-year-old son added plenty of sprinkles and happily ate the lot, so it can’t have been too bad! We used ordinary table salt as that’s all our local Co-op had in stock, but maybe rock salt might be worth a try. We’re also tempted to try cream instead of milk next time to see if it makes the ice cream a little richer. Like most good experiments, there was a bit of trial and error involved, but that’s all part of the fun! Shake Up Some Summer Science! Part science experiment, part summer treat – make your own ice cream with just a few simple ingredients! What To Do: 1. Pour the milk, sugar and vanilla into the small bag and seal tightly. 2. Fill the larger bag halfway with ice and add the salt. 3. Place the small bag inside the larger bag and seal. 4. Shake, roll and squish the bag for around 5-10 minutes until the mixture turns into ice cream. 5. Remove the small bag, wipe it clean and enjoy your homemade ice cream! The Science Bit Salt lowers the freezing point of the ice, making it extra cold. This allows the milk mixture to freeze into delicious ice cream while you shake, roll and squish! Raring2go! Tip: Why not add chocolate chips, strawberries or sprinkles for an extra-special summer treat? 25 Raring2go! RECIPE
