i made a dope hi-lighter pipe when i was bored at home. i poked a hole big enough for the nubby thing on the cap (or the bowl) to stick in firmly. i poked holes in the end of the cap. for the shotty i poked a fair sized hole in that white piece on the end, i think its the most ideal spot on any pipe. i gutted and cleaned out this hi-lighter a while ago, so it was clear and non-inky.
i got the question tho, i know it's plastic and it melts. i put a flame to it in my school cafeteria. i my first instinct is to use tinfoil to cover the bowl. would that be enough, or is there anything better.
