The forehead thermometer is a disposable strip of plastic with liquid crystals embedded into the strip. To take a person's temperature, one places the strip against the person's forehead. The liquid crystals react with the temperature of the skin. After waiting anywhere from a few seconds to a few minutes, depending on the brand, the crystals will change color. The thermometers have a number line that shows the temperature based on the color displayed.
