my drawing robot

I built a drawing robot with a cup, electric toothbrush, markers, and rubber bands. First I put the toothbrush trough the bottom of the cup. Then I put the markers on the side and used the rubber bands to make it stay. I took off the tops of the markers and turned on the toothbrush and the markers rubbed across the paper causing it to draw.
