Step 1: Take yer regular 'ol tape.
Step 2: Find t3h polarizors
I also have a polarized glasses, which I'll use from now on for convenience.
The direction of the polarization of the glasses is right and up.
The direction of the polarization of all the other small ones is diagonal, they all came from LCD displays (smart... prevents blackouts with polarized sunglasses
)
To show the effect, I hold one of the polarized sheets diagonal in front of both eyes and in one situation the result is transparent and in the other it's opaque.
When holding it vertical, it's half-transparent, so we won't use this anytime soon
Step 3: Inspect the tape
I placed a piece of tape between a U-shaped object, in this case a peg.
The tape is not polarized. Whichever you hold it, it stays transparent.
Step 4: The magic.
Place the tape in between two polarizers. Wait.. The polarization changes?
Let's do that again, now with the other eye
It really happens.
What about in front or behind both polarizers?
Nothing happens
Does it always work when in between, I mean even with odd rotations between the two polarizers? Let's place the polarizer vertical again, so the polarizing directions differ by 45 degrees.
The effect still happens, and just as strong. Complete darkness is possible even though the polarizers don't commute.
What about two tapes between the polarizers? I'll place two tapes on top of each other on the peg, both in the same direction.
What? It doesn't go bright and dim anymore, but changes from blue to yellow and back.
Step 5: t3h fun
Remember, tape on the side behind both polarizers stays invisible? Idea! two-sided screen. One polarizer with tape on both sides, I can create two distinct images, of which only one is visible at any time.
Try to guess what's on it....
Guess again, it's TAPE!
Now with the polarized glasses in front off the camera:
And the back side
Huh? Let's see that again, closer.
Multiple colors? Yes! by rotating the tapes with respect to each other.
Question: Try to guess how I did the gradient on one side..
[edit]
Video of the effect, with rotations and flipping.
