A MightyOhm Geiger Counter samples radioactive decay from a martini glass that contains a small amount of uranium. If the number of clicks in a set period is even, the robot dispenses vermouth into the glass. If the count is odd, it dispenses gin, therefore creating a wet or dry martini based on the random process of radioactive decay.
