I have been using this idea/device for a while. It saves SO MUCH smoke, and gets you beyond high for just a small amount. I dont see its name or idea circulated much on "best ways to smoke" lists or whatever. Just wanted to hear some thoughts about waterfall bongs, likes, dislikes from all the GC community. I personally love both my waterfall and my bong Merlin. just waterfall bong helps out when my weed is running tight.
