Green Machine – 9" Glass Percolator Bong

This bong has a classic, timeless design, with the addition of a unique percolator. Sturdy 4mm-thick borosilicate glass provides a nice feeling of durability to this piece, while the 4"-wide base provides stability on flat surfaces to avoid any tipping or accidental drops. Within the cylindrical chamber is distinctive curved tube-style percolator: Smoke travels into the green cylinder, then is forced through 6 curved tubes for maximum water filtration. This creates a neat visual effect, while efficiently pulling out impurities and lowering the temperature of smoke for silky-smooth hits.
