Liquid Crystals are amazing chemical compounds that exhibit properties of both solids and liquids. The molecules in these liquid crystals are free to flow like a liquid and arrange like a solid. The three states of matter to which every foundational chemistry class introduces us -- solid, liquid, and gas -- turn out not to be quite so clearly delineated as they might seem. Liquid crystals represent a sort of mixed state, not quite solid but not quite liquid. While molecules that make up a solid are arranged in a fixed pattern and molecules in a liquid move freely, molecules in a liquid crystal will tend to point in a particular direction, but not with the uniformity of a solid.
