Step by step guide on putting together Sportscar Racer #1 (11:42 minutes in length).

Sportscar Racer #1
The first racer has a simple Darlington transistors circuit that when completed, allows you to just turn the switch "on" and watch it race away!Sportscar Racer #2
The second racer uses a CDS cell configured to "turn on" the racer when its dark. To use this racer, just turn the on/off switch to "on" and set it on the floor. As soon as you turn the room lights off, this racer will start moving. Sportscar Racer #3
The third racer is the opposite of the second racer. After building it you set it on the floor in a dark room and turn the on/off switch "on". Nothing happens until you turn the room lights on, then the racer takes off!
