What are zeolites, and what do they do in cat litter?

Video · 1:50 · Crafty Clover explains, from A Million Whys Book 27

Zeolites are crystals full of microscopic holes and tunnels, like a sponge made of rock. Water and other small particles slip inside and get trapped. Some cat litters and water filters use zeolites to soak up moisture and smells. Chemists call them molecular sieves because they let small molecules in and keep bigger ones out. They are found in nature and can be made in labs.

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. What are zeolites, and what do they do in cat litter?

The Big Idea

Some crystals are full of tiny holes! They're called zeolites. And they help in cat litter!

Holes and Tunnels

Step one: Holes and Tunnels. Zeolites are crystals full of microscopic holes and tunnels, like a sponge made of rock. Water and other small particles slip inside and get trapped.

Uses

Step two: Uses. Some cat litters and water filters use zeolites to soak up moisture and smells. They help keep things fresh and clean.

Molecular Sieves

Step three: Molecular Sieves. Chemists call zeolites molecular sieves because they let small molecules in and keep bigger ones out. They are found in nature and can be made in labs.

A Closer Look

Let's take a closer look! Full of holes. Like a sponge. Freshen litter. Clean water.

Quick Facts

Quick facts! A single teaspoon of zeolite has a huge inside surface area. Full of tiny holes. Trap bad smells. Called molecular sieves.

Think Like a Scientist

Now, think like a scientist! Pour the same amount of water on two plates. Soak one up with a paper towel. Soak the other with a kitchen sponge. Which soaked up more? How is this like zeolites?

Outro

Zeolites are crystals full of microscopic holes and tunnels, like rock sponges. They trap water and small particles, so cat litters and water filters use them to soak up moisture and smells. They're called molecular sieves. Science is amazing! Keep wondering and keep exploring! Share what you learned with someone at home, and see what they think!
