What are tiny invisible particles?

Tiny invisible particles are super small things that we can't see, but they're all around us, like dust, but even tinier.

Imagine you have a big bag of sugar. Each grain of sugar is tiny, but if you could break it down into pieces so small that they’re like dots on a piece of paper, those would be tiny invisible particles. They are everywhere, in the air we breathe, in the water we drink, and even inside our bodies.

Think of a sandbox. You can see all the big grains of sand, but if you had a magnifying glass so powerful it could zoom in like a superhero’s vision, you'd see that each grain is made up of tiny invisible particles, like little building blocks. These tiny particles are called atoms or molecules, and they're what everything is made of.

Even though we can’t see them, we can feel them! When you blow on your hand, the air moves because it's full of these tiny invisible particles. They’re like little friends that help make our world work, even if we don’t notice them most of the time.
