It takes an army of humans and machines to create the humble tennis ball. While most of us rarely think about the work it takes to create something as small and relatively common as a tennis ball, it turns out the process is surprisingly complex and full of steps you might not expect.

In the short video above, filmmaker Benedict Redgrove goes behind the scenes at the Wilson tennis ball factory, capturing the step-by-step process of creating a batch of balls. The video is full of massive machinery, great tubs of glue, giant rolls of neon yellow wool, and of course, factory workers who ensure the entire monumental process goes smoothly. Simultaneously informative and mesmerizing, the video provides a rare peek into the production process of that most mundane piece of sporting equipment—the tennis ball.
