How to Grow A Lead Crystal Tree! Old Alchemy Demonstration.

The video tutorial by the Backyard Scientist demonstrates the tree of Saturn experiment, where lead crystals grow on zinc in a lead acetate solution. The experiment, referenced in historical texts, involves a single displacement reaction. Observations reveal the fragility of the crystals, which oxidize quickly. An alternative attempt using a penny results in a flat mass of crystals.

What did ancient alchemists believe about the lead crystals formed in this experiment?

What happens to the lead crystals when they are taken out of the water?
