Drop a Coin, Get Holy Water
The world’s first vending machines appeared in Roman Egypt—dispensing measured doses of holy water in temples. No chips or sodas, just a few drops of the sacred stuff. You paid for a blessing, not a snack.
Hero of Alexandria’s Ingenious Design
Hero of Alexandria, a Greek engineer working in Roman Egypt, invented a slot machine in the 1st century CE. Pop in a coin, and a hidden system of levers opened a valve, releasing just enough water for the ritual—ensuring fairness in the temple.
In Egyptian temples under Roman rule, visitors dropped a coin into a metal slot. The weight tipped a lever, releasing a measured splash of sacred water. Invented by the engineer Hero of Alexandria, these machines were designed to stop people taking more than their share. No loose change? No blessing for you.
