Rainbow experiment

We've been doing some rainbow activities lately that show how new colors are combined from various other ones (and how when you add all the colors, you get brown. We get brown a lot.). The girls have little colored pellets they can add to their bath that they love. But those are only every few days and only at most two colors combined.

This experiment let them set it up then see the slow change as colors merged with each other. Easy to set up too, just water, mason jars, food coloring and paper towels, but the results were vivid.

Right after adding the colors and the paper towels. Didn't get a shot of the girls doing this since, food coloring. But they remembered which colors they'd made later!

After about a day. I was really impressed at how vivid the colors were; only purple looked a bit muddy. Green was by far the best: Ellie kept saying over and over, "Yellow, and blue.... make green!!"
