Each wind-up is designed to detect the edge of the surface on which it drives; when faced with a sheer drop off the dining room table, the wind-up will swerve away, changing its direction to avoid falling! The style options include a tank, fire engine, airplane, bulldozer, bumper car, and UFO pod. The tank's barrel and the bulldozer's blade are both adjustable. Thees make for an excellent party favor or stocking stuffer, and can be given out as a fun prize at school by teachers, or for any contest.
