Using Bicarbonate Of Soda To Make FIzzing Sensory Play Activities

What Do Children Learn From Fizzing Bicarbonate of Soda?

Fine Motor – As they squeeze the pipette to release the vinegar or lemon juice onto the bicarbonate of soda.

Communication and Language – As you explore the activity together adding in new vocabulary as well as words they are already familiar with.

Colour Recognition – As they explore the different colours within the tray and watch how they change as they mix together.

Creativity and Imagination – as they test their own ideas and create a narrative to their own play. 

STEM – As they begin to explore the reaction that takes place. When the vinegar touches the bicarbonate of soda it causes a chemical reaction, the gas that is escaping and creating the bubbles is carbon dioxide.

How To Make Tate-Safe Paint

Just Grab

  • 1 cup of bicarbonate of soda
  • Distilled vinegar or lemon juice
  • Food colouring
  • 2 ½ tbsp of water


  1. Pour the bicarbonate of soda into a mixing bowl and add a few drops of food colouring.
  2. Combine the two until the colour of the mixture is how you want it, and spread evenly throughout.
  3. Pour in the water a little at a time, mixing to combine. You only want enough water to help the mixture stick together.
  4. Mould the mixture into the shape you want and leave it to dry for 24 hours.
  5. When ready to play, pop the shapes onto a shallow tray and pour some distilled vinegar into a cup.
  6. Squirt the vinegar onto the shape to watch it fizz.

What Is The Best Way To Clean Up Coloured Ice?

Cleaning Up Your Child

Remove any dirty clothes and pop them into the wash. Wipe your child down with warm soapy water, or bathe them depending on how messy they are.

Cleaning Up A Small Tray

Pour any excess vinegar and bicarb into the sink and wash the tray with warm soapy water.

Cleaning A Large Tray

I would avoid doing this in a large tray because the mixture will be hard to scoop out of the tray.

Cleaning The Surrounding Area

Wipe up any excess mixture with some kitchen roll, then wipe over the surface with an anti-bac wipe and mop the floor.
