I’ve seen this project on lots of super kid-stuff blogs, but I wanted to try it myself and post the results. Because fizzing colored bubbles are lots of fun. Oh, and this doesn’t require building a volcano.
You’re basically just letting kiddo drop colored vinegar into a pan of baking soda, which of course going to make little fizzy puddles. The great part is adding color to the vinegar. That makes it very engaging for kids.
This is a very easy project to get together — you probably already have everything you’d need in the house. And it’s fairly easy to clean up.
A large pan (like a glass baking dish)
Baking Soda (a small box)
Small containers to hold food coloring
I also recommend something to cover your table or surface that you can wash or easily wipe, since drops of food coloring can stain.
Cover the bottom of your pan with baking soda like so, and add a few drops of food coloring to each little container of vinegar (one color to each).
Now let your kids use the dropper to suck up the colored liquid and squirt it into the baking soda. So fun!
And when it was all done, we simply washed it down the drain.
An easy little project to entertain the kids for a bit. I wish I could say I completely explained the science behind it to my son, but what I did tell him was that the colored liquid and the white powder would ‘hiss’ at each other. He loved that.
Try this if you haven’t already!
