Subject: Re: What is a gravity bong?

The easy way:  Cut off a 3 inch hole in the bottem of a 2 L pop thing.
poke a hole in the cap, put a bowl on it.  get a bucket of water.  (with
cap off) put the bottle in the water.  put cap on.  light  tabacco(ha) as
you slowly pull up bottle.  stop pulling out bottle before the bottom is
out of the water.  take of cap.  put mouth on bottle.  push down rapidly
and inhale.  2 L of smoke are now in your lungs,, like it or not. (human
lung capacity is about 2 L.)  repeat if needed.(almost always
needed.)-roger
