Build this Rattle Writer using just a pool noodle, electric toothbrush (found for $1 at dollar stores), a plastic knife, washable markers, rubber bands, googly eyes (optional but fun), paper, duct tape, and a ruler. Once you have built your Rattle Writer, let the engineering begin! Can you get it to draw a straight line? Curly cues? Add to it – how about arms, legs, an outfit of clothes, hair? And don’t forget to shout – IT’S ALIVE! – when it starts rattling across the paper!
