Well this is how I've done it...Just cut out the amount of coke you want in there on a mirror or whatever...and cut out the same exact amount, and half that amount of baking soda, then throw you coke in there...easy now..put water on that coke so it turns to liquid, now throw your baking soda in there, you may need to put alittle bit more of water in there, just so you have enough water that will cover the shit up...not too much now...and cook it not with the flame directly under the spoon, but enough where it can heat the spoon up...I assume you are using a spoon, right? and stir the liquid with a toothpick, kind of stiring it into a ball as it cooks, and once it is all holding together...take it off of the heat so it can dry, and there you have a rock. But with smoking the shit...the best way is "follies". Ever hear of them, ever see the movie "Traffic", where the chick is taking hits of "H" with the rich kid, well same thing, except with rock. Take a piece of foil, and put alittle bit of water on the foil, so it's just a little wet, and sprinkle your rock on there, now you need a funnel, also made out of foil, or you can just use an ink pen or something like that, and now apply the lighter underneath of the foil, and watch as the gas comes up, thats what you will be breathing in with your funnel or straw. Good luck and have fun!!!
