Hi-Si offers scientific approaches to your smoking and vaporizing experience. By maximizing cooling capabilities and minimizing drag each piece delivers an ideal hit every time. Eliminate hot, dry rips from your life with a perfectly percolating work of art.
The queen-mother of percolation the Double Geyser looks like you took one bong and stuck it inside of another and somehow connected them. The bottom chamber is filled nearly to the top of the water markers. When hitting the water moves from the bottom chamber through each step of percolation and finally into the mouthpiece where it is cooled by the ice catch. This heavy piece takes a big lung to prime but once it gets rolling is smooth sailing.
