If the tape or the melts ya the fumes will get to u and be NASTY!!!!!!!!! but i think you should make somtin better...get any plastic bottle and a socket. Turn the plastic bottle so its not standing up, on its side. The burn a little hole(smaller than the circumfrance(sp?) of socket, this helps if its smaller so the pipe will be air tight), while it is still warm squeeze the socket in the hole. BOW you have one...thats what i did b4 i had a bong
