Lately the Beans has been trying to figure out what colors mixed together make what other colors, so we have been doing a bunch of activities that help support this curiosity. He mixes bath bead colors in his bath at night, he has been mixing food coloring in different batches and he paints with liquid watercolors (which mix beautifully, by the way). Yesterday I put out an invitation that incorporated color mixing with one of his favorite things to do right now...race cars! Although I must say that he wasn't okay with getting his cars "mucky," so we used trains instead ;)
What you need:
trains or cars
a piece of long paper with painters tape
washable tempura paint
What to do:
Tape down a long piece of paper on the table or floor.
Pour the paint in thick strips at the starting line overlapping some colors for better mixing.
