A bong with Maximum percolation capabilities. It has a total of four UFO percolators, 3 smaller ones which are directly fed with air by the fixed downstem onto them. Another large one sitting in the can chamber above the beaker base. The holes in each of these 4 percolators diffuse and filter the smoke for optimal intake conditions. There is quite a lot of diffusion that goes on making the 12.5" water pipe milk up rapidly and spread all over. Working best with about 2 inches of water, the filtration will be optimal for a cool smooth smoking session. It features a large 45 degree angled 18mm female joint which houses the 18mm male all glass bowl. The deep bowl allows for more to be placed in it. This scientific glass piece certainly gets our approval for it's percolation system and smooth flow. On sale for a limited time while supplies last!
