It's WeWWWW.

Hello and welcome to Wewow.

A hands-on crash course and fun fun 101 for science seekers and inventoritos everywhere.

I'm Mindy.

And I'm Guy Raz.

And we've got a serious mystery on our hands this week.

The golden fake teeth that I got Grandma G-Force for her

birthday have gone missing.

We found one clue so far, and we're looking for more, which is why I brought out my trusty

magnifying glass, which has something called a convex lens.

So convex, meaning that it bulges outwards and lens like something you can see through

that angles light in a certain way?

That's exactly right.

You see, light travels through the lens, and because the lens is curved, it changes the direction the light travels.

So that means when we look at something through a convex lens, it looks different than if we were looking at something with our regular old eyeballs?

Exactly. And in this case, it makes small things look bigger.

I figured it could help us notice things we wouldn't have noticed before.

Great idea, Detective Guy, private eye. Here, let's try it out.

Okay, so let's try pointing the magnifying glass at the ground near the safe.

Whoa, look at how big the carpet fibers look, like big fuzzy chanka pillars.
