Description

See my blog post about this video: https://www.patreon.com/posts/how-does-pull-24042503

The Pull-Back Toy Car is an incredible piece of engineering! This is sometimes called a "Wind-Up" toy car. This videos covers the specifics of the mechanism: the motor chassis, the 5 gears, and the torsion spring. We'll talk briefly about gear ratios, gear trains, and also cover why you hear that mysterious clicking noise when it winds up enough.

The toy cars in this video were downloaded from Blend Swap and I had some help for the others.
