The automatic holy water server with coin-collector
(the first slot machine in human history)
It is a reconstruction of the invention of Heron of Alexandria which allowed the believers to take holy water automatically after throwing a coin into a pot. The coin fell onto a balance which moved and opened a conic valve releasing a certain quantity of holy water.
