From the brains behind Brains On, this is the Moment of Um.
Moment of Um comes to you from APM Studios.
I'm Ruby Guthrie.
I like to think of myself as pretty easy to be around.
If I see you out in the street and you say, hey Ruby, I'll probably smile and yell back hey pal, even if I'm having a tough day.
It's more than likely that I'll just keep that to myself unless I know you really, really well.
I wish there was a way for me to share my emotions without actually having to tell anyone.
Sort of like a secret code.
Did I hear someone say secret code?
Maybe.
Did I hear someone say they don't like to talk about their feelings?
Well, not exactly.
Did I hear someone doing the dance between wanting to be open and honest and yet creating a boundary around their innermost thoughts and feelings?
Well, yes.
Then do I have the product for you.
I'm Lady Magnus.
Nice to meet you.
Come, come, come into my shop.
Oh, so sparkly.
These are mood rings, and they are a beautiful little piece for you to wear on your finger.
They communicate to everyone around you how you're feeling.
So people will know right away whether you are Rapturous Ruby or Relieved Ruby or even Enraged Ruby on any given day.
Okay, but how does it work?
And how did you know my name?
And how did you know about Enraged Ruby?
Ah!
Ah, yes.
Mm-hmm.
We had a customer in here yesterday with the same question.
My name is Catherine, and I live in Houston, Texas.
My question is how do mood rings work?
Hi, my name is ned thomas and i'm a material scientist and a materials engineer.
The mood ring, it's this cool thing that you put on your finger and it has a color which changes uh, during the day and people relate it to.
Somehow the ring knows what you're thinking uh, or feeling.
And The ring doesn't know what you're thinking, but it knows whether or not your temperature of your extremities, your finger, if your finger temperature is going up, the ring is going to change a color in a certain direction.
If the temperature goes down, it's going to change color in another direction.
And then that would beg the question, why does your temperature go up and down?
You know, if you exercise, for example, and you run in, lifting weights, climbing stairs, vigorous exercise, you use a lot of oxygen and your heart's beating and your blood's flowing and when your blood flows it brings warm blood from inside your uh interior to your fingertips and and your face and so forth.
A lot of times people look at somebody's face and say boy you're, you're red, your face is very red And that's because the blood has gone into the blood vessels and swollen them up near the surface.
And your skin changes sort of color.
It also changes temperature.
When people get sick, their temperature goes up a couple of degrees.
Or if it goes more than a couple of degrees, they're very sick.
Well, mood rings, they play the same game.
But now you don't want to target 98.6 or 100.
You want 80 or 82 degrees.
And then when you exercise, your mood is going to change.
Or if you're feeling good, maybe just taking a walk and it's pleasant and the sun's out and you're having a talk with your friend, you feel good.
Your mood ring will glow a certain color that will be designed to say, I don't know bright, green or something, because you're feeling good.
And when I'm in the green mood, I feel good.
Humans, we like to think about magic and we like to think about sort of special effects that are, you know, controlled by gods or goddesses or something or other.
And so there's this mystery about, I mean, there's no wires, there's no buttons to push.
At any particular time, there's something that is deemed cool.
This ring is just a thing, but it knows how you're feeling.
Of course, it doesn't know how you're feeling.
It knows what your temperature is, but the temperature is influenced by how you're feeling and what you're doing.
So now that you know all about mood rings and you understand that they're not really telling us our moods, but rather our temperature, maybe you're asking yourself why you don't see too many people wearing them.
Well, they're not a super modern accessory.
They were invented in 1975.
The 1970s had a lot of fads.
That's when something becomes super popular, super fast, then fades away almost just as fast.
Bell bottoms, disco music, circle sunglasses, and something called a pet rock were big back then.
And sometimes fads come back.
Speaking of, gotta go.
I'm late for my 2 p.m. disco jazzercise class.
