What are the contents inside an Etch-a-Sketch?
- Aluminum:Anyone who has used an Etch-a-Sketch would remember the red plastic toy with the glass drawing window. So what’s inside an Etch-a-Sketch? The vast majority of an Etch-a-Sketch is plain old aluminum powder, ground extremely fine. It’s what coats the glass screen of the toy and gives it that distinctive grey color. The only other major component is a metal pointer, the position of which is controlled by a couple of strings attached to the knobs on the faceplate. Moving the knobs scrapes the aluminum powder away, creating the drawing.
