Using Saran Wrap As A Polarizing Filter

Posted by timothy on from the now-shake-an-egg dept.

cdneng2 writes "Here's a University of Toronto research paper on how to use ordinary Saran Wrap as a polarized filter to turn your laptop into a stereoscope. From the paper, cellophane (costing mere pennies) proved to be a better half-waveplate than a commercial half-waveplate (costing hundreds of dollars for the required size) for rotating the polarization of white light. The same paper is cited in www.mygeekdom.com." Cellophane wonders may never cease.

      Not likewise. Saran Wrap (aka plastic wrap) is not a trademark name for cellophane. It's a different substance. Pretty important to this article smart mouth.

    Lazy. Lazy.

    Here's some links. Cellophane is made from cellulose.

    While plastic wrap (aka Saran Wrap) is made from "plastics" like PE and PVC.

    Unlike many english names. These ones make some sence.
