yo your fucking stupid kid. perculation is the act of braking up smoke into many smaller bubbles as opposed to less, bigger bubbles with a regular downstem. so therefore, that is NOT a fucking perced bubbler because it has open ended downstems. so how about these pictures, they illustrate the same thing i figured you could understand from previous pictures. you fucking n00b.
this last pic is perfect, so that double bub would NOT be a perced bubbler because the downstems are open, get it yet? sorry to everyone thinking this argument is pointless, but i needed to prove heath wrong because he is so fucking smug all the time.
hey hey hey, smoke weed everyday.
