We'll admit, it's not something we'd normally cover - but there's something genuinely interesting about this.

Or maybe there isn't. We can't be sure. All we know is that we watched this video and were utterly fascinated by it. Also, it's sort of weirdly hypnotic.

Take a look.

Who knew this amount of work went into tennis balls? Also, maybe it's just us, but you'd have genuinely thought the manufacturing of tennis balls was almost entirely automated. It looked like there was a surprising amount of people working on it, even just getting the lettering right for it and all.

Every day's a school day. That video also could have benefitted from this kind of music as well.
