Visual demonstration: This handson Galton board shows the bell curve formed by beads and a peg grid, illustrating within random chaos. How it works: Rotating the plate releases steel balls; as they strike nails they bounce left or right, collecting in bins to form a nearnormal distribution. What you gain: An intuitive, observable link between randomness and statistics; reinforces probability, distribution laws, and stochastic processes; no electricity required; durable and reusable. Specifications: compact desktop footprint fits standard desks or lab benches; robust frame; includes steel balls; clear observation area for tracking paths; simple operation and quick setup. Uses: Physics or statistics labs to illustrate distribution laws; classroom demonstrations to explain randomness and probability; science fairs or display stations to communicate core ideas to visitors. Why it stands out: combines handson exploration with clear visual results; reliable, repeatable demonstrations; easy to integrate into existing curricula or exhibits.
