This video came up in my yt feed a couple of days ago. I watched the rice cooker video that was also hn front page a few weeks back. And now The Algorithm thinks I like Japanese undustrial manufacturing videos. I'm not complaining.

The thing that confused me though: why punch out the middle, only to put it back in again? It doesn't look like they're made from dissimilar metals like Euros?
