If i was you Iâ??d buy a fairly cheap bong because as someone said if you buy something like a roor and your mum or dad finds it there goes a hell of a lot of cash the one Iâ??ve got at the moment only cost me something like £16 and Iâ??ve had no problems with it, i keep it in a draw that no one ever needs to go in... as for concealing the smell, poor out the water or what ever you choose to put in it after every session, maybe something other than water would hide the smell more but i haven't tried anything else so i can't really help you there but just open a window that's what usually works imo :rasta:
