On its quest to free the world from the burden of fossil fuels, Tesla has unfortunately hit some speed bumps with the production of its Model 3. So instead of relying on batteries and electricity for power, perhaps the company should consider this four-wheeled contraption which runs on a gigantic spring-powered mouse trap.

Based on a simple science experiment that many of us tried in grade school, Kevin Kohler‚ÄĒaka the Backyard Scientist‚ÄĒused the oversized mouse trap he built earlier this year as the engine for a very-basic roadster. Its top speed is disappointing and its range is abysmal, but you‚Äôll never need to remember to plug it in at night, or fill it up every few days. Even better, as far as I know, there‚Äôs no waiting list to get one.
