I have tried doing this on attempts but cannot quite figure out what needs to be done due to my lack of science.. so far I took a tube about as long as the bottle and had it going from the cap down, but then it only filled the tube with smoke.. does anybody know what needs to be done or hav you accomplished it?

(sorry if typings bad i just took 2 regular gravity bongs of "green crack")
