I’ve had this idea for a few years that the Golden Rain experiment a double displacement reaction between potassium iodide and lead nitrate might be one of the early inspirations for alchemy and the idea that lead might be transformed into gold.

In this video I attempt to make all of the compounds required for this reaction from ingredients that would have been accessible in ancient history.
One of the key ingredients, lead nitrate, would not have been available at the time according to my research so instead I attempt to use lead acetate which I was able to make via acetic acid in vinegar.
I believe the most likely ancient source of an iodine component is the ash from burnt seaweed.This video was unscripted and filmed as I made my very first attempt at testing this idea. I take a while to reach the final result but I hope you enjoy watching the process!
