This fourth quick project required some prototyping as well. When I used mechanical pencil lead, it was much too fragile, and broke several times within five seconds of rolling up the paper.
I wanted to use something stronger, and thought about charcoal, but didn’t have any artist charcoal on hand. So I grabbed some charcoal from the fireplace, and ended up with a pencil that would get the job done.
This is another great project to set students loose to see what they can come up with!
