Add a sulfate solution: BaSO4 precipitates!
I know this because our class just did a lab and I wrote a 15 page paper on this. Essentially, when you make a supersaturated solution, you heat a saturated solution up until it is realls UNsaturated, and then you add more solute to bring the heated solution CLOSE, but not TO, saturation. Then you cool the solution down gently, without agitating it, and if you're lucky, none of the solute will precipitate, making the solution, of course, supersaturated. Now, the balance between these particles is really frail. So if you add more solute to the supersat. solution, all of the originally dissolved solid(only the solid that you put in the hot solution) will crystallize. Basically, one moment there will be a tiny crystal in a test tube full of liquid, and the next moment the test tube will be half full with crystals. sooo....yeah
