thats a good idea, exept i can see that breaking alot of GonG type bongs(more likely downstems), becuase of the leverage that it puts on the downstem. But on an Oring one it could be ok. I wouldnt do it though, id rather have somethign i know wont break my bong no matter what.

but if someone has one of those tiny 20$ cheap 8" o ring bongs theyd be willing to sacrifice for the purpose of finding out if the glass pebbles are ok, then that would be cool.
