Tree Percolator IN ACTION!

A Tree Percolator incorporates any number of thin tubes with holes at the bottom into a circular dome, which resembles low-hanging branches dangling from a tree. The arms are connected to the bong through a stem, which draws the smoke up and into the tree percolator. The holes or slits at the bottom of each arm are submerged in water and the smoke is forced through them, cooling it on its way to your mouth.
