Golden Rain (precipitation of lead (II) iodide)

This isn't one of the scheduled demonstrations, but I did it today and though some of you (whoever you all are!) might enjoy it. Apologies for the lousy editing!

mine didn't stay so shiny for so long... :(

@disastergirl888 two possible reasons for that: 1) it cooled too fast 2) it wasnt very pure. If you do it on a large scale (mine was a 2L flask i think) it helps it cool slower

Looks like the atoms/molecules of lead iodide were still attaching to other molecules of it same kind, just like you would grow your monoammonium sulfate crystals.
