THE PRODUCT IN MOTION
Steel balls strike pins as the triangular frame turns, producing changing tones and patterns of random motion.
Video & text guideTHE ACTIVITY & MECHANISM
Repeated random deflections guide the falling balls along different paths, introducing the idea of a probability distribution. Collisions also make the metal pins vibrate. Pins with different dimensions produce different pitches, combining a visual probability demonstration with sound.
Turn the triangular frame.
Watch the balls fall through the pins.
Listen to the changing tones and compare the patterns.
