Everything in the world around us is made of atoms, science video explains just how small these particles are

Everything in the world that surrounds us is made of atoms. That's right, pizza, office buildings, cars, clouds and all the other things that are part of our everyday life comprise armies of such elementary particles. Heck, we're made of atoms ourselves.

Apart from their behavior, what's terribly fascinating about atoms is how small they are. No, really, they're insanely teeny tiny. Check out the video below and see for yourselves if you're having trouble imagining just how small atoms are when compared to the things we see and touch.

As detailed in this animation put together by the folks behind YouTube channel Kurzgesagt, the width of a single human hair is the equivalent of about 500,000 carbon atoms neatly stacked one on top of the other. Besides, just one human fist contains about a gazillion atoms.

Just to put things into perspective, the video argues that, were the atoms that make up just one of our fists the size of marbles, this body part of ours would be about as big as our entire planet. Now if this piece of information isn't downright mind-blowing then I don't know what is.

What's interesting is that, as small as they are, atoms pack quite a lot of empty space inside them. Thus, it is estimated that, were all the atoms that make up the Empire State Building to lose all the space inside them, this landmark would be the size of a grain of rice.
