All you really have to do is fit an electric toothbrush into a Halloween decoration so that the bristles of the toothbrush make contact with the ground and it will move around in strange and mysterious ways. The size and weight of the decoration will determine how well the electric toothbrush motor is able to move it, and the angle at which the bristles make contact with the ground will determine the direction that it moves. You may want to use additional brushes so that it moves more smoothly, like I did to the severed hand decoration that I turned into a bristlebot in the video below.
Be sure not to miss the full tutorial.
It’s easy to imagine how much fun it would be to casually place this bristbot on the floor at work (or home).
