  • Could you explain what happendo with three polarized crystals?

  • It would just add another layer. If all three layers were aligned the same the light would come through. If any two of them were at right angles the light would be blocked. Many variations in between those extremes.

  • I have heard that, if you put two polarized layers in 90º the light is blocked (as we can see in your video) and we can't see throungh them BUT if you add another more with the same angle as the first layer (in 90º with the second) the light can come through! is this true?

  • No, it is not true. Two polarizing filters at 90 degrees to each other will block the light no matter what else you add to the stack.
