Boss up with the Color Tip Matrix glass bong, this one requires some serious stoner skills. At a whopping 19 inches, this huge glass bong is filled with various percolators to ramp up filtration and deliver ultra-smooth hits. Light up the bowl and watch the smoke reach the fritted disk percolator, one of the most powerful percolators around. Smoke will then travel up through the chamber through the matrix percolator and again through the turbine percolator. Percolators are not only nice to look at, but the functionality it provides in a huge bong is unmatched! The extra filtration in this big bong is impressive. Pop a few ice cubes into your glass bong to cool down your hits and pro tip - put some food coloring into your ice cubes and let the percolators put on a colorful show!
