dude hold the flame about half inch to a full inch away from the bottom of the glass bulb. keep it on there it may take a few seconds.. which may seem like eons when youre stoned lol....for the vapers to start to appear. now when they start to appear just shake up the bud inside of the bulb just so it goes up and rattles around and falls right back over the hot part of the bulb with you still holding the flame on......more a ton more vapers should start to appear and from then on out just keep shaking and looking and when you think you have enough in there take ure finger off the carb and suck them in... dont make it like a quick burst, slowly so you dont breathe in the reefer left in there. do this multiple times for a "bowlb"
