It's just a bong with no bowl slider. That's what's missing, is a slider/bowl to go in that slot. Not a mystery, just missing an important piece.
Nochowderforyou Reviewed by Nochowderforyou on . Mystery Piece. This piece confused the hell out of me for a second. because it is too small to be used as a bong, so i seeked my dad for council. i asked him "This is one unconvential bong, what did you use it for?." well i never used it as a bubbler, but as a pipe. so i guess its ment to be a pipe shaped like a bong.
