Today’s most preferred material by smokers for making water pipes is glass. The reason for this is twofold. First, glass tends to provide the best performance, considering a water pipe is subjected to extreme heat and moisture over and over again. Glass doesn’t split, crack, warp or bend under these conditions, even after long-term use. Second, glass doesn’t alter the flavor of the herb being smoked as other materials (like wood) do. When you smoke from a Sloppy Hippo glass water pipe, all you taste is herb. We typically use lab-quality, borosilicate glass between 3mm and 5mm thick, which makes it more resistant to breakage. So, go ahead and get your very own Sloppy Hippo water pipe today!
