I've never used concentrates before, I bought a glass nail for ten bucks but im not sure it fits my bong. I drop it in the joint and everything is sealed up so much that I can barely pull on it, too much resistance. My friend (who never dabbed before) said it was probably too big. I just don't know how to make this thing work. I bought a cheap torch lighter, it works fine though. I don't have a dome, how can I make one? I know I can use tin foil but how do I actually form it?
