Fizzy Lemonade

Saturday Science Fizzy Lemonade

It doesn't have to be Lemonade Day in order to have some fun with that delicious lemony drink. Check out this Fizzy Lemonade experiment and discover what makes soda fizzy.
A bit of lemon here and a bit of baking soda there and before you know it you'll be an expert at making your own fizzy drinks!


Fizzy Lemonade experiment materials

  • Lemon
  • Drinking glass
  • Water
  • 1 teaspoon of baking soda
  • Some sugar to make it sweet


  1. Squeeze as much of the juice from the lemon as you can into the glass.
  2. Pour in equal amounts water and lemon juice.
  3. Stir in 1 teaspoon of baking soda.
  4. Give the mixture a taste and add in some sugar if it needs to be sweeter.


The mixture should be bubbly and taste like a fizzy lemonade drink. If you added some sugar it might even taste like a lemon flavoured soft drink you've bought at a store.

The bubbles that form when you add the baking soda to the lemon mixture are carbon dioxide (CO2), the same bubbles you'll find in store-bought fizzy drinks. The carbon dioxide bubbles formed through a chemical reaction between the lemon (an acid) and the baking soda (a base).

This experiment was adapted from the Science Kid's article, "Make a Lemonade Fizzy Drink."
