Hennig Brand was an alchemist on a mission: transmute urine into gold. In the 17th century, he gathered about a thousand gallons of pee and boiled it down to separate out a substance that he believed would give him gold.

Today we use it in explosives, fireworks, and fertilizers — and that red strip on the side of matchboxes is just red phosphorus waiting to react to the sulfur on the match head.
