Scientists at the University of Richmond have taught rats how to drive tiny cars. By re-purposing a food container, adding wheels and some controls, they began rewarding the rats with Fruit Loops for being able to navigate about. When the rats actually mastered the art of driving the tiny vehicles, their stress levels actually went down!
According to New Scientist:
They constructed a tiny car out of a clear plastic food container on wheels, with an aluminium floor and three copper bars functioning as a steering wheel. When a rat stood on the aluminium floor and gripped the copper bars with their paws, they completed an electrical circuit that propelled the car forward. Touching the left, centre or right bar steered the car in different directions.New Scientist
The rats became so good at driving, they could drive through a maze in search of food. Check out the video below to see them in action:
