Fizzing Lemon Halves
Baking soda sprinkled on a cut lemon foams up the moment a spoon presses it. Two minutes of setup, and a small child can repeat the eruption over and over.
What you need
- Lemon
- Baking soda
- Teaspoon
- Deep plate or metal tray
- Kitchen towel
How to play
- Cut the lemon in half yourself, as this step is for the adult, and lay the halves on the tray.
- Let your child squash the cut side with a spoon so the juice comes up.
- Spoon baking soda over both halves.
- Press with the spoon again and watch the foam climb.
- Add more soda every time the fizzing dies down.
