Light twirls through the crystal structure until it dizzily reaches the eye.
Taking advantage of the properties of light, we can discover so many details about the microscopic world that are otherwise hidden from our eyes! For example, by playing with the direction in which light wiggles, certain crystals can suddenly shine with rainbow shapes that reflect their structure. This happens because light can split into waves that wiggle in different directions and move at different speeds. When these two waves interfere, we see beautiful colors that we can then analyze to explore the properties of the crystal.
