Originally made from leather and stuffed with wool, today’s tennis balls are manufactured from raw rubber to have an optimal bounce height that can make or break a play for professional players. But how do the iconic yellow balls get that bounce in the first place?

Commissioned by leading tennis ball manufacturer Wilson to document the manufacturing process of their tennis balls for the US Open, filmmaker Benedict Redgrove flew to the Wilson tennis ball manufacturing facility in Thailand to document the amazingly complex manufacturing process for the not-so-simple ball.

Says Redgrove:

“It was hot, loud and the people who worked there worked fast. So much beauty in each stage. I love the mechanics of how things are made, it fills me with great pleasure. I hope you enjoy the film.”

Why the ultra-bright yellow felt? It was first introduced in 1972 as “Optic Yellow” after research showed that it was the easiest color to be seen on color television sets.
