Vending machines have existed since ancient Greece — dispensing holy water
Some trivia is so bizarre it forces you to rethink your entire understanding of the world. Check out the fact below, see how others reacted, and scroll down to dive into the verified science and history behind it.
The first recorded vending machine was invented by Hero of Alexandria around 50 CE. It was designed for temples: when a coin was dropped in the slot, it landed on a pan attached to a lever, which briefly opened a valve and dispensed a fixed amount of holy water. When the coin slid off the pan, the lever closed again. Hero was also the inventor of the first steam engine (the aeolipile) and programmable theatrical automata. The holy water machine predates Coca-Cola vending machines by nearly 2,000 years.
Vending machines feel like a product of industrialisation — a 20th century convenience. Discovering that the mechanism was solved 2,000 years ago, and used specifically to commercialise religious ritual, reframes both ancient engineering and modern retail.
