I use a coffee grinder to collect weed crystal, or "kif". What I do is grind my weed, dump it out into a container, then grind the grinder full throttle, upside down and shake it a bit.

Then I grab this little tiny brush that came with my electric shaver and brush the crystal out of the grinder lid into a pile. Then when I want to get super blazed I just simply grab my bong bowl, toss a glass screen in it, sprinkle some grinded weed, then add the crystal and then sprinkle a bit more weed on top just to get things burning.

Then I grab the pocket torch and hold it just close enough that the weed JUST lights. And the result is always mouth watering, face numbing crystal rips.
