Good opportunity to share this life hack: I used to end up with a mess almost every time I used my coffee grinder, much like the picture in the article. Eventually I learned that this only happens with very dry beans. Adding a few tiny drops of water before grinding is enough to get rid of it pretty much completely. Since making coffee already involves water it’s as easy as dipping a finger and then running it through the beans.

It actually helps the extraction from the coffee grounds too, not just for reducing mess.

Similarly dry air can be a literal component killer when working with electronics. Sometimes a humidifier is needed to ensure static build-up doesn't go too far.
This is actually an interesting challenge for places that work with electronics assembly at an industrial scale; they have competing drives to keep humidity high for ESD mitigation, but also deal with a lot of moisture-sensitive components whose acceptable exposure to free air (after baking, but before reflow) is measured in hours (and substantially worse with higher humidity).
Thanks for this tip!

I just tried, worked like a charm :)
