With the bottle bong, watching others take huge rips is just as fun as smoking from it yourself (just don't try to take a sip). The discreet inline percolator forces smoke through the water generating a plume of bubbles that quickly filters out contaminants. Due to the vertical design, inline percs are much more durable than other styles of percolators and are very effective. You can take huge, smooth bong rips with just one perc and the included glass bowl since it packs very deep. The bottle stands upright on a stable green base and is blown with thick glass on all sides, making it a great piece for sharing or taking along with you on the go.
