You Will Need:
- Icing Sugar
- Citric acid which can be found at the ‘herb and spices’ aisle at the supermarket.
- Bicarbonate Soda, better known as baking soda.
- A cup per-person
- A spoon per-person
Add twenty parts icing sugar to one part citric acid and one part bicarbonate soda.
Mix it together.
And eat… it is that simple!

Why Does This Happen:
The fizzing on your tongue is caused by the water in your saliva allowing the citric acid and bicarbonate soda to dissolve. Scientists call this ‘in solution’. As the citric acid and the bicarbonate soda are now in solution they can react much more easily as the molecules can contact each other much better.
What’s the gas? Carbon dioxide (water is produced in this reaction as well).
Variables to test
- Change the amount of citric acid
- Change the amount of bicarbonate soda
- Change the amount of icing mixture
- Try adding crushed jelly crystals!
From colour changes to slimy science, we’ve got your kitchen chemistry covered!
