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.

    I am simply filtering the available light to the water through this filter known as ordinary clear-wrap. This is a science experiment I expect Class credit for this!

    Boy, I wonder if that would have helped back then.

    This is pretty neat stuff. Making 3D monitors using saranwrap is like starting nuclear fusion with old coffee grinds.

      It's just not good coffee unless it can melt the cup :)

    I think what makes this dupe particularly amusing (poignant? telling?) is the fact that it links to the article it duplicates. Sheesh, don't these editors read anything?

      I don't know what you guys are getting so worked up about.
      "Stereoscopic technique for generating 3D displays from cellophane and a laptop"
      doesn't sound anything like
      "how to use ordinary Saran Wrap as a polarized filter to turn your laptop into a stereoscope"
      to me! I mean... "polarized". Definantly some new information there, right?

      I, for one, welcome our new Dupes Overlords.

      And I'd like to remind them, that as a trusted Slashdot reader, I can be useful in submitting more duplicate stories.

    Dude, put the articles side-by-side and cross your eyes. You'll see it in 3D!

    Mike Tyson, bite somebody. News is dry and we're repeating posts about polarization to effect 3D. Does anybody really want to sit with their eyes crossed for any period of time? To to see things in 3D? BTW, the rest of the world comes in 3D for free.

    (1) wrap yourself in saran warp
    (2) wait for polar bear
    (3) polar bear kills you
    (4) you stay fresh for weeks until polar bear is ready to finish consuming you
    (5) profit
