Using Saran Wrap As A Polarizing Filter
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.
So how does an editor manage to link to the original story on slashdot, which references the same article link, without realizing it's a duplicate?
Cellophane != Saran Wrap
