Moody?

 I'm not sure what the attraction is for mood rings...but I saw some with Rachel when we were out today.  We tried them on and I like the way it felt so we each got one, and I got one for Susanna, too.

It's funny how people will look at their ring and go, "I'm nervous, I'm thinking, I'm happy" and never realize that it's the heat of your hand that changes the ring's color :)

It's just a flat strip of liquid crystals with a protective coating. The crystals respond to changes in temperature by twisting and reflecting different wavelengths of light. When the temperature of the liquid crystals changes, so does their color. 

According to the rings here, Susie is passionate about something, I am happy, and Rachel is an interesting mix of calm and nervous!

So even though it's a bunch of bologna to think that a ring can draw your body's energy and display your emotion in a color, I still think they look neat...
