Make a rubber-band powered wooden racer! A great, pocket-sized toy to explore transformation of energy. Bascially a precursor to the wind-up car…
This kit uses a wooden spool, skewer, washer, paper clip and rubber band to put together (instructions provided) to create some speed! To make it go, wind the skewer clockwise several times, then set the whole thing down on a flat surface. The rubber band unwinds, spinning the spool, and making the ‘car’ roll off.
