This 'sparky' little wind-up critter may seem aimless, but take a closer look. The axle on this simple machine is bent to produce a complex pattern of motion. Can you predict where it will go? Also, take a look at the wheel on the top of the machine. Two pieces of flint circle around a strike plate, producing brilliant sparks as Sparklz makes its way across a flat surface. Perfect for the study of simple machines, friction, and for prediction activities! Adult supervision recommended for children under 14. About 9 cm (3.75 inches) tall. Color may vary.
