Material: acrylic plastic.
Color: Yellow, White, Red
Size: 40.5 x 30.5 x 3.5 cm.
Application:
Turn the device upside down, pour all the balls into the V-groove, insert the insert plate, then turn it over so that the V-groove is on the upper part of the device, pull the insert plate to drop the balls, the collisions with the peg arrays are randomly distributed, the pegs are equally distant to the left and right of each other, and each horizontal position of the upper level is exactly in Middle middle of next level s When the balls come into contact with the peg arrays, the pegs all have a 1/2 chance of falling left or right and then hitting the next layer of pegs etc. until they fall into the narrow slots in the base plate, causing a number of balls of the same size to fall from the entrance, and as long as the number of balls is fair. Large, it stacks up in the base plate in a pattern that approximately corresponds to a normal density function (i.e. high in the middle, low at the ends and low in the middle). An old bell pattern with left-right symmetry, where N is the number of layers of nails.
