~3D VIDEO~ !!!POLARIZED LIGHT TRICKS!!! (Polarized Light Sunglasses Physics and Polarized Explation) SCIENCE EXPERIMENT

Crazy Chris is checking out polarized light and shows you some wicked cool tricks you can do with your sunglasses.

Objective: to understand polarized light.

Materials Needed:
~ Pair of Sunglasses (best with plastic frames)
~ Light Source
~ Piece of Plastic
~ Tape

Step 1) Get a pair of sunglasses with a plastic frame and pop out one of the lenses.

Step 2) Place your sunglasses with just one lens in front of a light source and place the lens you popped out in front of the lens and then rotate it 90 degrees.

Step 3) Get a piece of clear plastic and some tape and add the tape to the clear plastic making an "X" and then on top of that a "+".

Step 4) Place the sunglasses with just one lens in front of the clear plastic, and with the lens you popped out place it between you and the piece of plastic and rotate the lens.

HOW DOES IT WORK:
To understand whats going on here you first have to understand polorized light. Normally light travels in waves in different directions, but when you polorize light you cause the light to be filtered so that the light travels in waves paralell to each other. Your sunglasses have a chemical filter on them made up of polorized molecules or horizontially lined up molecules which filter out all light that is not traveling on a horizontal plain. When you look at the light through the two sunglass lenses your seeing horizontailly polorized light. when you turn the lens so its facing at a 90 degree angle, the first lens vertically polorizes the light so by the time to the light gets to the second lens which is horizontally polorized, it filters out this vertically polorized light blocking the light. Same thing happens with the colors in the tape except one difference. Each time light passes through something it gets bent slightly. As the light passes through the peice of plastic and the layer or layers of tape it cause some of the horizontally poloirzed light to get bent out of its polorized feild. When you hold the lens horizontally this blocks out certain colors that are no longer polorized on a horizontal plain. Which is why the colors change when you roate the lens.
