The Galton Board is a 7.5” by 4.5” desktop probability machine. This delightful little device brings to life the statistical concept of normal distribution. As you rotate the Galton Board on its axis, you set into motion a flow of steel beads that bounce with equal probability to the left or right through several rows of pegs. As the beads accumulate in the bins, they approximate the bell curve, as shown by the yellow line on the front of the Galton board. This hands-on Galton Board allows you to visualize the order embedded in the chaos of randomness.

These are highly polished solid metal flip over tops. They have a chrome like finish and are excellently machined. Simply spin it as normal and watch it suddenly flip over and then continue to spin upside-down. These flip over tops (often known as a The Tippe Top) were originally invented in 1950 by the Danish engineer Werner Ostberg. His inspiration can from a visit to South America where he had seen local people playing with a small, round fruit. When they turned it by the stalk like an old-fashioned spinning top, it would spin for a second and then invert and spin on the stalk. However some credit should be given to Helene Sperl who in 1891 patented a Wendekreisel in Germany. However the patent ran out and it was never mass produced. These tops are made from polished aluminium and are 29mm in diameter.
