Science is well-loved around here – both at home and in my preschool classroom. This simple and fun science experiment was no different. The kitchen was filled with “oooooh!” and “aaaaah!” aplenty as the kiddos explored fizzy stars.

Our fizzy stars were inspired by Cathy James’ newest ebook Super Sensory Invitations to Play. Full disclosure – I was given a free copy of the ebook in exchange for an honest review. As always, the opinions here are my own!

We set out to make a fizzy night sky with this fun science experiment! My son set a few star cookie cutters in a glass pan, along with a moon cookie cutter. We spooned baking soda into the cookie cutters, trying to keep most of it inside the stars and moon! Then we added glitter, and we were ready to go!
I placed a large bowl of vinegar out, along with some of our favorite squiggly eye droppers. The kiddos used the droppers to add vinegar to our baking soda stars. They had such fun watching the fizzing and bubbly reaction that ensued! The bubbles ended up making the glitter look like it was shimmering and sparkling, just like stars in the night sky.
After a bit, we decided to add some beautiful gold liquid watercolor to the vinegar. Engineer was interested to see if it would color the reaction and look more star-like. It didn’t end up working out like that, but we did discover something interesting. With the addition of the watercolors, the reaction was even foamier than before! This led to more oooohing and aaahing over the fizzy stars!
