AN EDUCATIONAL DEVICE ABSTRACT OF THE DISCLOSURE A simple, durable, inexpensive educational device for demonstrating properties of motion to children is described. The device comprises a horizontal stationary elevated support means which is a sandwich configuration of two rigid board members kept apart by spacing elements; a first string suspen- sion means movably disposed about the spacers in the support means; and a second string suspension means connected to the first string suspension means. Both string suspension means are so coupled to one another that the first suspension means is capable of horizontal movement and the second string sus- pension means is capable of independent vertical movement relative to the first suspension means. By manipulating the suspension means it is possible to vividly demonstrate the principles of motion to children.
