This is a pretty classic chemistry demo called the Golden Rain. It involves precipitation of gold-colored lead iodide from a hot solution as it cools down. It is formed very simply by combining a soluble iodide salt with a soluble lead salt, in my case potassium iodide and lead nitrate. • A write-up can be found on my blog, here: http://thehomescientist.blogspot.com/... • Music: Reverie (small theme) by _ghost of ccmixter.org. • link: http://dig.ccmixter.org/files/_ghost/... • Freely usable for all purposes under the Creative Commons license.
