Now, just pour the solutions in the beakers back and forth for about 10 seconds and the solution will suddenly turn super dark, almost black.įor more details, check out Steve Spangler's full tutorial. Solution C: 50 mL boiling water + 2g soluble starch Step 2: Combine the Solutionsīeaker 1: Mix 50 mL of Solution A with 50 mL of distilled water, then add 10 mL of Solution C.īeaker 2: Add 50 mL of distilled water to 50 mL of Solution B. Solution B: 1000 mL water + 4.3 potassium iodate Solution A: 1L distilled water + 1.2g sodium metabisulfite + 4g concentrated sulfuric acid + 10 mL ethanol The iodine will stain skin and fabric, though, so you might also want to put down some plastic before you start. As far as safety goes, throw on some goggles, a pair of gloves, and don't drink anything and you should be golden. If you can get your hands on those chemicals and a couple of beakers, you can easily recreate this experiment at home, but it may take a few tries to get the timing right.
