How to Do the Fizzy Bottle Caps Science Experiment

Kids will love making the bottlecaps fizz!

When the color is revealed, they will love adding more and more vinegar until the colors mix.

I love how easy this is to set up and how interested preschool and kindergarten children get in making the baking soda and vinegar reaction until it’s gone. It’s the perfect introduction to chemistry for kids!

Fizzy Bottlecaps Science

This is a great way to introduce young children to doing science experiments. Even if they don’t fully understand the scientific terminology for what is happening, they are learning about chemical reactions.

When baking soda and vinegar are mixed together, the acid from the vinegar reacts with the base of the baking soda.

This creates a chemical reaction that releases carbon dioxide and the gas causes the mixture to fizz.

Squeezing the pipettes is a great way to incorporate fine motor skills during this science activity.

You could also include a counting activity by asking your little one to count the number of bottle caps, the number of food coloring drops added, or to count the number of times they squeeze the pipette for each bottle cap.
