I have no idea how I came up with this thread, other than from cleaning out my bowls and ash tray after a session.
If for no purpose, let this this thread serve as a reminder to NEVER simply toss your burned shisha and coals in the garbage, because there is a possibility that they can light up and cause a fire! Also, never ever flush foil, either. It's bad for your plumbing!
Whoops, guess my ash aim was off, guess the shisha from the burned soggy remains!
