This is something that, oddly enough, I hadn't thought of doing. I filled my bong with crushed ice this morning and stuck it in the coldest part of the freezer before I left for work. By the time I got back, it was frozen pretty nicely, and the bowl had a beautiful frost on it. I didn't bother to pour any water into it becuase I was afraid that it would freeze into a block, thus preventing a good draw, so I just hit it as is, and it was so smooth that it makes menthol taste like car exhaust! I've seldom taken hits this big without my face turning red and my lungs nearly exploding. Shit, 1e64, thanks for this thread. Works like a charm. When my father gets home from teaching his summer course, he'll have to try it out!
