Charcoal on concrete

My son got the idea to burn the end of a stick in the fire and use it to draw. First he was making some drawings on the concrete bench in the patio, then he ground the stick on the concrete and made dust that we mixed with water and made ink. He was pretty fascinated with the whole process and even brought some to school to show his teacher.
