Did you know?
The earliest vending machine was invented by a man named Hero Alexandria in the first century. Hero Alexandria, a Greek engineer and mathematician, created a machine that accepted a coin, before dispensing holy water. At the temples where citizens worshipped, this device ensured that people were not taking more than their fair share of holy water.
When users inserted the coin into the machine, it would land on the pan which was connected to a lever. The weight of the coin on the pan would be heavy enough to pull on the lever, enabling the valve to open and flow holy water. The pan continued to slant until the mass of the coin would drop. When the coin had completely fallen off the pan, the lever retracted, and the valve would close.
