This percolator bong from Black Leaf® with 'Flaming Skull'- printing has a particularly elaborate cooling system: It consists of a diffusion adapter, diffusion chamber (Erlenmeyer-piston), a 6-arm percolator and Ice-Notches. A diffusion-chamber? That's right, something entirely new to the world of glass bongs. It means that a bulbous diffusor chamber is integrated into the bongs base. Since it consists of colored glass it is extra pretty to watch the smoke fill the diffusion-chamber and then search its way up through the lower diffusion-vents. And apart from its pretty appearance it is also a decent cooler.
