http://forum.grasscity.com/apprenti...o-doesnt-have-small-chillum.html#post11620087 As promised in the above thread, here's some photos of a waterfall bong that I made last night using the chillum as a bowl. Actually worked remarkably well. For anyone who isn't aware of how waterfalls work, the bottle is filled to the top with cold water (thinking of using crushed ice as well today?), the bowl is lit and then the water is released through a hole in the bottom of the bottle, sucking the smoke in. So for my design I used a Southern Comfort liquor bottle and a 3" glass chillum as the bowl. I had a bit of an accident making the hole in the bottle though. I don't have a diamond drill bit, so I read that a drastic change in temperature should crack the glass. I heated the a single spot with a lighter for about 20 seconds and then poured a little bit of cold water on the spot and boom, cracked. In fact, the entire bottom of the bottle basically fell off, so in the end I have to use tape to put it back together (still works brilliantly). Anyway, photos. The milk photo isn't brilliant because I was rushing so the smoke didn't go stale, but there it is!
