Color Mixing, Two Ways

I usually only let J paint with one color at a time, because I'm mean like that, but I decided it was time to start expanding our palette. This also allows for mastery of color mixing facts, which always seemed to me to be the key to preschool science LOL. :)

First we did yellow and blue paint on Jackson's easel...

And then I set up this Pinterest-inspired activity, wherein the kiddo spoons colored dilute vinegar onto baking soda. It's colorful and fizzy! This kept him occupied for an incredibly long time, until all the fizz was gone and everything in all three containers was green.
