Film cannister (or other small container) to put the powder in.
Step 2: Grind it up!
Take the Black Pepper and grind it up in the Mortar and Pestle for about ten minutes. The longer you grind it the better it will be. You could probably use a coffee grinder but then your coffee might taste a bit weird.

you could also use a personal fan to disperse the powder.
