OverviewThis instrument is a teaching instrument designed to study the statistical regularity of the velocity distribution of gas molecules according to the model designed by British biologist Dalton to study random phenomena.InstructionsInvert the instrument, pour all the balls into the V-groove, insert the insert, then flip the V-groove in the upper part of the instrument, pull the ball into the ball, collide with the nail array and randomly spread, the distance between the nails The left and right sides are equal, and each horizontal position of the upper layer is just in the middle of the next layer. When the ball hits the nail during the falling process, it falls to the left or to the stone with a probability of 1/2, so I also touched the next layer of nails, and so on, until I fell into the slot of the bottom plate, dropping a lot of balls of the same size from the entrance. As long as the number of balls is quite large, it will pile up on the bottom plate. A density function graph that approximates a normal state (ie, an intermediate height, low at both ends, and a left-right symmetrical ancient bell shape), where n is the number of layers of the nail.PrecautionsThe instrument consists of plexiglass, should be handled with care, do not collide, and store in a cool dry place after use.

• This instrument is a teaching tool to study the model of random phenomena, the statistical regularity of distribution to explain the gas molecule movement rates
• With this instrument, the statistical tool of statistical regularity of the velocity distribution is explained by gas molecules
• The instrument consists of a plexiglass plate, an array of nails, a V-shaped groove, an insert panel, a slot, and the like
• Incredible tool for physical laboratory equipment or as a decoration in your laboratory that make learning physics experiments efficiently
• Well suited for use in schools, educational displays and collectibles. A great addition to your laboratory equipment
