One of those simple projects I’ve meant to try with our son for some time – having fizzy fun mixing colored vinegar and baking soda.
This was a great way to use up an old container of fridge baking soda. It was long past time to switch it out so I just dumped the entire box into a small baking pan. We added a few drops of food coloring to four small bowls with vinegar. (No blue as I forgot we used it up making the “moon dough” for his party favors last month!)
We had a good 30 minutes of fizzy fun play with this project. Our son loved squirting the colored vinegar into the pan and watching it fizzle and bubble. Then he tried sucking up a bit of the baking soda with the eye dropper and squirting it into the vinegar bowls – more bubbling fun!
He poured colored vinegar between the bowls – mixing the colors. Finally he poured it all into the pan and mixed both with the eye dropper and his hands. It was a brown mess by then, but still a fun textural experiment! We’ll definitely try again.
