What is inside your flat screen TV? If you have looked at a calculator or a mobile phone display, used a laptop or a flat screen TV you've made use of liquid crystals in the form of liquid crystal displays (LCDs). However, liquid crystals have a whole range of uses, from thermometers to bullet proof vests! Liquid crystals are also found in living cell membranes and even the slime in your soap dish is made of liquid crystals.
