View all articles

Today, little scientist, we will make an experience that fizzes and foams!

That’s right, we’re going to make hearts that transform like magic before your eyes.

Do you want to try?

Let’s go!


  • Baking soda
  • Vinegar
  • Food colouring (2 colours)
  • Glitter
  • 2 bottles
  • Water
  • 2 heart-shaped moulds (optional)
  • A container


  • In a bowl, pour your baking soda and add some glitter.
  • Add a little bit of water until you get a thick paste.


  • Put the paste in your two moulds or make two heart shapes with your hands.


  • Put your hearts in the freezer for a few hours.
  • Take them out and wait a few minutes.
  • Remove them from the moulds and put them in your container.
  • Put vinegar and food colouring in the bottles.


  • Pour the vinegar on the hearts and look closely!
  • What is happening? The hearts foam up and crackle!


You can continue to add vinegar until the hearts disappear completely!


I hope you had fun making this activity with me!

Come back soon!
