Ground some freeze dried nescafe with a pestle and mortar so still not the finest powder in the world. Ok, now the aroma is getting a bit annoying :roll: :D

Guess you're not much of a coffee lover then. I have an electric burr grinder, but I didn't want to take it all apart after grinding charcoal, so I just used the drill as an electric motor to drive the hand-powered grinder. I tightened the burr as far as it could go without fear of it causing it to grind itself away. The powder that I produced will hang in the air by itself once disturbed, and even looks like it is evaporating if the air around it is disturbed :P. Dust masks are a must. I could send you a sample of airfloat if I can figure out a way to package it...

You must learn to love the scent of coffee :wink:.
