ABSTRACT:
A variety of toy polariscopes are simpler in design and less costly than precision instruments used in scientific research and stress analysis of materials and structures. The toy polariscopes are designed for a variety of objects that may exhibit photoelastic properties such as glass, plastic, Plexiglas, gel candle material and other gels, and even edible photoelastic objects. They are specially designed for objects of various sizes with a variety of purposes such as objects to enhance learning in a variety of conditions and experiences. Special objects are designed to go with the toy polariscopes such as edible and inedible photoelastic objects, photoelastic candle material, a variety of photoelastic/photoplastic stands capable of a variety of displays in interaction with other designed photoelastic objects capable of a variety of interaction and displays. Other optical phenomena may also be observed.
