Snow is, okay, so what makes, we're really in a detail here.

I like this, let's go there.

A single snowflake is not fluffy.

No, no, a single snowflake is fluffy.

And what happens is,

If you have snow that is just pure hexagons, they fit together pretty well.

It doesn't have a lot of air in it.

And they can also slide against each other pretty easily.

And so the snow can be pretty, I think avalanches happen sometimes when the things tend to be these hexagonal plates and it kind of slides.

But then when the thing has all these arms that have grown out,

It's not, they don't fit together very well.

And that's why the snow has lots of air in it.

And if you look at one of these snowflakes and if you catch one, you'll see it has these little arms.

And people, actually people often say, you know, no two snowflakes are alike.

That's mostly because as a snowflake grows, they do grow pretty consistently with these different arms and so on.

But you capture them at different times.

as they fell through the air in a different way, you'll catch this one at this stage, and as it goes through different stages, they look really different.

And so that's why it kind of looks like no two snowflakes are alike, because you caught them at different times.

Well, science, if you do what people might often do, which is say, okay, let's make it scientific.

Let's turn it into one number.
