Flour in a jar

Making Fizzy Sherbet

When I was a kid reading books, I always wanted to find a way to delve into the story a little bit more and somehow merge the world of the characters into my own. As a writer, I love when I can embed that opportunity into my books.

In The Kingsley Kids and the Bouncy Goo, the strange science teacher, Ms Higglebottom, returns with more experiments. Along with making slime with the children, they also mix ingredients to make fizzy sherbet. 

The recipes for both the slime and sherbet are included in the back of the book, and my nephews helped me make the sherbet recently. Check out the video below, especially Henry’s adorable reactions to tasting citric acid and bi-carb soda at 0:43!

Live the adventure…

Make Your Own Fizzy Sherbet


  • 1 teaspoon baking soda (sodium bicarbonate)
  • 1 teaspoon citric acid
  • 5 tablespoons icing sugar


Place all of the ingredients into a bowl and mix them together. Make sure you mix them well, because the first two ingredients above don’t taste very good by themselves!

Store in a small, airtight container.

Ready to experiment?

Try substituting two of the tablespoons of icing sugar with flavoured jelly crystals and see what flavours you can create.

      Hi. I’m guessing you’re talking about finding the citric acid? In Australia (where I’m based) it’s found in the baking section of the supermarket. But I checked online and it said in USA it’s often in the canning or canned food section of the shops. Hope that helps.
