Baking Soda Science (and Art!)

Smell & Guess

An La Leche League friend told me about this activity, tooting it's easy prep and high interest rating.

It's a simple vinegar and baking soda experiment with a twist; food colouring & eye dropper.

O chose three colours to mix into the vinegar.
Then used the eye dropper to drip vinegar into the tray of baking soda.

Mixing baking soda and vinegar creates a chemical reaction that produces CO2 (carbon dioxide) and water. The chemical name for the two ingredients is called acetic acid.
The fizzy biz.

Of course O could not stop there.
After dripping vinegar for a while, she decided to create her own experiment.
She piled up the baking soda like slushy snow and poured heaping spoons of vinegar over top (volcano-style).
Then she took baking soda covered spoons and dipped them in the vinegar!

Finally, she switched the experiment from science to art, dumping all of the tinted vinegar onto the tray and tracing rivers!
