now heat it up and let it cool down slowly so you get large hexagonal flakes

Remarkable is that neither of the ions is colored, but somehow the precipitate is (due to iodoplumbate-complex formation).
It is very neat to expand your experiment by heating this precipitate and letting it cool again.
The solubility of lead(II)iodide in cold water is very low, but the solubity of the stuff in hot water is very much greater.
Letting the solution cool down again will yield golden crystals suspending from the faint yellow solution.

We did that at school today. It's simple and fun.

a nice precipitate of lead iodide there.
