Gravity Bongs ?

Have you ever used one,tell me what it was like

 

well it definately recks you
quick
it always suprised me how many i could do.
just plain giddy.
the trick is to find those very rare 3-liter bottles. perfect size.

 

HAHA graves are the best you need to make one out of a 4 liter and it will be a one hit one kill

 

never use milk jugs no matter what any one says bout em. they colapse too easy.
FUCKIN GREAT WAY TO SMOKE. just fill it, put your mouth on the opening, and pull the fuckin triger.......lotta good times had on a grav

 

we used coolers and 3 liter bottles and the bowl of a metal pipe screwed into the cap

 

i used a 2 liter bottle and a pitcher and wow it got me so high man
