It's time to break out the food coloring again. If you're looking for a great indoor activity that the little ones will probably want to do over and over again, try teaching them about color.
We saw this fun project over at Little Lovely and it reminded me of something I did in preschool. You'll need some clear cups or glasses, food coloring and water. Add a bit of water to each up and drop in several drops of food coloring in the primary colors - red, yellow and blue. Then mix the primary colors into secondary colors - orange, green and purple. And so on. Ask your kids what color they think will result when all of the colors are combined together.
