How it Works?
This car works with the mousetrap being the engine. When the back axel it wound up, it wraps the fishing line around it, which then pulls the lever on the mousetrap back (this will build up the energy). When the back axel is let go, the lever gets pulled back to its original position, spinning that back axel with it, which makes the car move. The wheels are attached to the body of the car through the ends of the ink cartridges. They serve as the axel. With the balloons on the back wheels, it allows the car to push from the ground, helping the car move. Without the balloons, the wheels would spin in place, because of minimal friction between the surface and the wheels.
