This electric racer kit is a steal! For $5, your child learns the basics of electricity while building his very own electric car! The instructions explain how batteries convert chemical energy to electric energy, which is then converted to kinetic energy by the motor and wheel axles. Kids get an up-close and personal look at how it all comes together, as they build a safari racer, putting the battery, motor, wheel axles, and wiring in the right place. Flip the switch and it's Go, Go, Go! A simple kit at an unbelievable price. (Tedco, $5.00)
