Mood rings were invented in the 70's. Mood rings achieve their colour changing effects by utilizing a thermochromic material, such as liquid crystal, that changes colours based upon the temperature of the wearer. The person wearing the ring could have poor, average, or great blood circulation and will affect the colour reading. External temperatures, such as a cold winter days can also affect the colour of a mood ring.
