How Does Mood Ring Work?

How do mood ring colors change? You may ask. The ring contains a faux gemstone, which is usually made of glass or quartz. It is actually a clear capsule that is filled with liquid crystal, which is thermochromic or has a thin sheet of thermochromic liquid crystal placed underneath. Liquid crystals are very sensitive to heat and they will change their position while responding to a drop or rise in temperature. Light has multiple wavelengths and our eyes see each reflected wavelength as a different color. Which wavelengths are reflected back and which are absorbed depends on the position of the liquid crystals, thereby causing the stone to change color.

Changes in the body temperature of the person cause the liquid crystal to reflect lights of different wavelengths, leading to a change in the color of the stone, resulting in mood ring colors. The liquid crystal present in mood rings is generally set up to show a neutral color (black) at an average skin temperature of humans, which is around 34 degrees Celsius.
