As soon as the eggs finished boiling, I put them in a tray (that came with an egg dyeing kit). O(4) and I drew on them with the crayons, and the crayon wax melted as we drew.
I was undecided about whether or not to allow E(1) to join in on this activity. However, it was a moot point since E understands "hot" and was not at all interested in getting near the hot eggs. She sat quietly and watched her sister draw.
After drawing for a while, O decided to shave her crayons and sprinkle the shavings on the eggs. What fun!
