The UPC 8" Bubble Water Pipe is a sister bong to the UPC 8” Pedestal water pipe. The difference is that this particular water pipe has a bubble base with a flat bottom. This allows for more water to be added for better filtration and cooling of the smoke. It has a 26mm diameter straight neck which isa little bit narrower than others to concentrate and condense the flavor of your smoke. Featuring a removable diffused downstem that is 18mm to 14mm with a heavy bowl. The diffused downstem is a simple yet very effective percolator especially considering that this specific bong uses more water due to it’s bubble bottom feature. The glass tube downstem contains holes or slits at its base under the water which allows the smoke to be filtered and cooled as it travels through the openings. In addition this water pipe features an ice catch above the bubble bottom. This allows you to use ice to further cool down the smoke for a smoother hit. Hand blown by UPC in California and made with premium borosilicate clear glass. This is a must have for any smoker’s collection.
