Abstract
A sky kaleidoscope system includes a polarizing film, a first plastic plate having a first transparent design, and a second plastic plate having a second transparent design. The polarizing film is sandwiched between the first plastic plate and the second plastic plate. The first and second transparent designs are photoelastic and/or light diffracting. The sky kaleidoscope may be held up to the sky and the plastic plates and polarizing film may be looked through to view resulting rainbow colors in the first or second transparent design.
Claims25
A sky kaleidoscope system, comprising
- a polarizing film;
- a first plastic plate having a first transparent design;
- and
- a second plastic plate having a second transparent design;
- wherein the polarizing film is sandwiched between the first plastic plate and the second plastic plate;
- wherein the first and second transparent designs are photoelastic.
A sky kaleidoscope system, comprising
- a polarizing film;
- a first plastic plate having a first transparent design;
- and
- a second plastic plate having a second transparent design;
- wherein the polarizing film is sandwiched between the first plastic plate and the second plastic plate;
- wherein the first and second transparent designs are at least one of photoelastic and light diffracting;
- wherein the first and second plastic plates comprise two sides of a cellophane envelope and the first and second designs are adhered to and/or part of the sides of the cellophane envelope.
A sky kaleidoscope method, comprising:
- holding a sky kaleidoscope system up to the sky, the sky kaleidoscope system comprising:
- a polarizing film;
- a first plastic plate having a first transparent design;
- and
- a second plastic plate having a second transparent design;
- wherein the polarizing film is sandwiched between the first plastic plate and the second plastic plate;
- wherein the first and second transparent designs are at least one of photoelastic and light diffracting;
- looking through the plastic plates and polarizing film to view resulting rainbow colors in the first or second transparent design;
- and
- removing the polarizing film from the first and second plastic plates and placing it in a cellophane envelope having other transparent designs on first and second sides holding the system up to the sky and looking through the cellophane envelope and polarizing film to view resulting rainbow colors in the other transparent designs.
A sky kaleidoscope system, comprising
- a polarizing film;
- a first structure having a first transparent design positioned on a first side of the polarizing film;
- and
- a second structure having a second transparent design positioned on a second side of the polarizing film;
- wherein the polarizing film is sandwiched between the first transparent design structure and the second transparent design structure;
- wherein the first and second transparent designs are at least one of photoelastic and light diffracting;
- and
- wherein the first and second transparent designs are asymmetric and non-periodic.
