The Galton Board is a gift for physics lovers which brings the concept of the normal distribution to life. Just by rotating the board on its axis, metal beads move in an unpredictable way through a network of pegs until they eventually accumulate in the bins, forming an impressive bell-curve shape – shown as the yellow line on the front of the board.

This remarkable device imparts order to randomness with every rotation and presents visual stimulation through colorful steel beads flowing through its multi-level structure. Boasting an impressive 7.5 inch by 4.5 inches, this probability machine serves as an eye-catching desktop toy and an educational gift that has delighted people since its invention in 1873 by 19th-century scientist Sir Francis Galton.
