A Galton Board is used to create normal distributions from hundreds of balls channeled by chutes. At each juncture, each ball has an equal chance of going left or right. Mathematical rules determine the probability of a ball ending up in a particular column. For example, for 8 levels of left/right channels and 256 balls, the resulting distribution would be 1, 8, 28, 56, 70, 56, 28, 8, 1, which forms a normal distribution.
