Package of 5 high quality polarized film sheets machine cut into 4" x 4" squares
Rotate two sheets placed together at 90 degrees and observe a significant shading / darkening effect as a result of the significant reduction in light transmission. Keep rotating them to observe them become transparent again when they are aligned again in the same direction.
Each polarized film sheet has a removable cellophane backing (see photo #2). It's not necessary to remove the backing for the light polarization effect to be observed.
This material is easily cut with scissors and can be used in applications outside of teaching such as on a dashcam or to polarize eye glasses or even security cameras.
