i saw this documentary on meth where they had a solution dripping into another one, and from each drop crystals crashed out..

i dont know if this is correct but im guessing the meth was soluble in the first solution and insoluble in the 2nd, but those 2 solutions were miscible..

so say i had methcathinone or methamphetamine HCL dissolved in distilled water, is there a solvent where i cud do as aforementioned?
