Eyedropping Liquid on Beans Before Grinding?

I remember seeing people taking an eyedropper full of some liquid and squirting a few drops onto their whole beans before grinding. I can’t remember if this is a recurring dream or if people are actually doing this in real life. Seems odd without knowing what the liquid is.

Anyone seen this before?

I saw some video… somewhere… though it was a water mister/spray bottle.

An argument about possibly controlling or having less fines?

It’s water, the reason for using it is to reduce static.

Seems unorthodox, but I’m sure extraction from that would be insignificant?

Yeah, the idea is to use a tiny tiny amount of water. James Hoffmann has a video about it on his Youtube channel. Seems very effective to me.

This got me thinking: why is there less static cling for espresso grinders? I know Mazzers have a little bit at the spout, and the K30s have even less it seems. How is this such a decrease compared to the huge static from an EK? Even espresso doses in an EK give off chaff and static.
