And even though Frenchie's wife is selling all that crap, Frenchie, to my knowledge, never used a vacuum. Put the product in the bag, dump dry ice on it and shake around, then find a place to shake out the tricomes. Scoop it up, get some turkey oven bag and cut a piece. Put the kief onto the bag piece. Then take an empty clear wine bottle 1.5 liters and fill it with boiling water. Close the bag over the kief and gently roll the bottle with hot water over your kief. After about 20 minutes, turning and rolling over, you should see some darker stain on the kief. That is the tricomes melting. You may need to do this several times (reading and re-reading this late fact, thanks for holding back Frenchie).
No vacuum EVER needed.
