like a bong you could hit upside down. very curvy. someone drew up a doodled design but i cannot find it!!! it probably is not an original idea and we werenโt able to actually make it obviously but this was sparked by my roommate and i trying to hit the bong laying upside down on the couch. it didnโt work. but we repeated the experiment with a 4 person team: the bong holder/lighter, the toker, and two people standing on the couch holding up the toker by his feet. this worked and was very successful albeit impractical
