Your kids love to draw, so why not have them learn the periodic table while doing it? This is idea behind Chemistry Crayon Labels, for sale for as little as 3 USD on the Que Interesante Etsy store. But how are the labels matched to crayons in a meaningful way?

A “flame test,” the analytic procedure to detect the presence of certain elements based on the color of flame produced, was used to determine the color. For example, barium burns green while lithium burns red. Just be ready for when your kids ask you to pass the “Boron” crayon!
