Do mood rings work in water?

Mood rings do not actually change color based on emotions, but rather due to changes in body temperature. The stones in mood rings are made of thermochromic materials, which means they change color based on temperature. When the stone is cold, it will appear as a different color than when it is warm.

Water can affect the temperature of the mood ring stone, causing it to change color. This is because water absorbs and retains heat differently than air. If you wear your mood ring in cold water, the stone may appear darker than it does when you wear it in warm air.

Wearing a mood ring in very hot or very cold water can potentially damage the ring or cause the color of the stone to fade. It is best to avoid wearing your mood ring in extreme temperatures, such as very hot or very cold water.
