Wow this was certainly a tasty wee science experiment - we made ice cream in two plastic bags. To create ice cream you need to create an emulsion which is when two liquids are forced to mix together. To make this magic mixture we need to slow down the molecules of the liquids. We do this by making the molecules super cold.

So ice cream in a bag - how did we make it? First we had one large and one small ziplock bag. In the small bag we added 3 heaped teaspoons of sugar and 1 and a bit teaspoons of vanilla essence for some flavour. Then we carefully poured into the small bag a cup of ‘Blue Top’ milk. We then sealed the small bag and put it in the big ziplock bag which had 3 cups of ice in it.

However, we needed to make the ice super cold to make our ingredients stick together. How to make ice super cold? Add salt! We put ⅓ of a cup of salt in our big bag and it suddenly got very cold. This happens because salt has a lower freezing point than water. The ice was starting to melt but the salty water was getting colder!

Now came the mixing part. We had to carefully shake and turn over our bags for 8-10 minutes. To help stop our hands from freezing, we wore gloves or wrapped the bags in a tea towel or some paper towels. The milk mixture got colder and colder until it bound together to make ice cream! Tasted pretty good too - especially with yummy sprinkles on top. In the Middles we certainly have an appetite for science!
