make a what most people call makeshift vaporizer (which in fact is commonly known as the homemade crack pipe) out of a light globe.
most people would get the point from this lol.
but here ya go (in very brief description)
wear gloves or have a rag teatowl ect ready to wrap and hold the globe when ever you think it may break IE: step 2
1: cut the metal piece off the top of the light globe NOTE you dont want to cut it all off u need to leave about a centimeter around the glass and flush (use a saw if possible its just ull need somethin sharp and serrated ro cut throug it
2: then what you want to do is poke a screwdriver or something long and hard (not what your thinkin) in the end and break the center piece off from the rim and empty it so your left with just the globe nothing on the inside
3: Then find a plastic coke bottle Tax the lid and put it on the end of the light globe (most should fit perfectly but if not use tape... wrap it around the rim until you can put the lid over top and have it say there and be an airtight lid
4: then what you want to do is melt a hole in the lid the size of a straw and put a straw in it ( u can opt to put another pinprick in the lid for airflow and what not)
5: put the hash in and light the bottom of the globe and suck the straw
or you could roll a smoke with the hash mixed through
or you could get some foil make a dish, spoon, canoe shape whatever the fuck you want really just something to hold the hash. then get a straw to suck the smoke and light the lighter up "Under THe Foil, not directly its not a bong"
alternatively buy some gauze sold in bong/porn shops all over the show
or you could just hot knife it
think about it here just a few possibilities
as for the condition you reckon its in it doesnt matter it still burns but dont expect too much no matter what you do if its not good hash
as for crumbly what do you mean they just might not have compressed it ehy
sorry for the way this came together im kinda in a hurry sorry
