Making my Preschool Science Bicarb Balls

Check it out! I’ve already written about our first foray into coloured vinegar and bicarb…in my preschool science colour and fizz post

I didn’t follow any recipe, simply added food colouring to water and added the water sparingly to the Bicarb until I was able to create a ball. I repeated until I had enough (in different colours) for the activity I had planned. Basically the littles had played with Bicarb in a powder form and I thought it might be interesting for them to play with it in solid form and liquid form (a misnomer on one account, being a solute rather than pure liquid, but they’re only 4 and 2 so I’m thinking they’ll not notice!).

I then set up the coloured balls of Bicarb. I had let them dry thoroughly over a few days in the containers. Keeping them in the mini muffin tins I placed them into the trays, with some plain vinegar in a beaker and the pipette.

They were eager to begin, but took the time to (impatiently) pose for a picture! I gave then some spoons to mix to maximise the fizz and we were done! Click on pictures to see larger version.
