Information about the Invasion Of The Bristlebots

Simply by snapping together the enclosed toothbrush head and motor, the 'Bristlebot' is made. The motor contains an eccentrically-weighted drive shaft - the movement of the weight causes the brush head to rise and fall and so it glides forward on its bristles. The effect is very impressive and, due to their size, they appear quite charming. Two Bristlebots are included per piece and, along with necessary instructions, the book provides further scientific information and suggestions on games to play and experiments to conduct.
