“Crickets and batteries not included”. A line that did not exist until someone made this bug powered racing car. You catch a cricket, put him in the car and motion sensors inside the car track the cricket’s motion, steering it left or right depending on which side of the cockpit the cricket has scurried over to. What a way to test animal intelligence. You can of course use any other insects, even cockroaches, but we believe crickets are the best. You can even add a little food into the food chamber so they can happily live in their racing cars.
