"Polarization" is known for sunglasses and 3D glasses that cut reflected light. Bees and birds can distinguish "polarization", which allows them to know the direction to return to the nest and to aim at the fish without being disturbed by the reflected light. In this workshop, we will use polarizing plates and cellophane to make "mysterious stained glass" in which colors and shapes can be seen and hidden depending on the angle. While freely creating works, you can enjoy learning about polarization, the mechanism of polarized colors, and the world of animal colors.
