What kind of Percolator design is this? If it specific, I want all my bongs to have these Percs. The design is super efficient at stacking bubbles up to the tops of the chambers bad ass. Almost like high end BC2009/2010 Bubblers. Every rip extremely fucks me up. Like no other. Hello GC, This is my first peculator bong, ive ripped many other's with stem/spiral perks before.
