ABSTRACT:
A device for exploring the transferring of motion from one body to another body which utilizes a motion transfer surface is presented. The device is a hollow structure for receiving an object which has a motion transfer surface on its exterior. The hollow structure may be a tube or a polygon, such as for example a pyramid. The hollow structure can be opened and closed so that the object can be secured therein. Preferably, the object is spherical. Further, the object may have a gyroscope seated within its interior. The gyroscope may be activated by waves having a frequency, such as for example sound waves or electronic waves. Further objects, each having a motion transfer surface may also be seated within the hollow structure. Preferably where two or more objects are present, each object has a motion transfer surface and is in frictional contact with another object. Additionally, a toothed ribbon suitable for use as a motion transfer surface is described.
