What you need (materials):
1. 1/2 a teaspoon of baking soda
2. 1 teaspoon of citric acid
3. 3 teaspoons of icing sugar
4. a small cup
5. a teaspoon [to stir it round]
We put all the ingredients in the cup together and mixed them. Then we tasted them!
When we put all the ingredients together I thought it woud taste disgusting, but when I had a taste, it was amazing! At first it was all sweet and then it fizzed up in your mouth. Our saliva mixed the ingredients together. It was the best sherbet I have ever tasted!!!!
