info: This is a home experiment where some starch, sugar and salt extracted from potatoes is put into a diluted solution of iodophor (sanitizer). What happens is that the iodine reacts with the starch to produce polyiodide chains with 'starch' forming helices around them, this structure gives the blue color.
