Coloring lets kids practice their motor skills and express their creativity, but could it also help them learn chemistry? These ingenious labels, designed especially for crayons, pairs waxy colors with the chemical compounds that make them.
Etsy seller Que Interesante makes these labels for crayons and colored pencils. Why pick boring old cerulean from the box when you can select copper sulfate? Those pheomelanin carnations need a little barium nitrate flame around the leaves. Perfect for the science loving kid or artistic chemist in your life.
