How Does The science of snowflakes with Brian Cox | BBC Ideas Work?

Snowflakes are tiny ice shapes that form in the sky and fall to Earth like paper snow.

Snowflakes start as water droplets, which freeze into ice crystals when they get cold enough. These ice crystals grow bigger by collecting more water vapor from the air, and depending on the temperature and humidity around them, they can shape themselves into different patterns.

Imagine you're building a snowman with blocks, each block has to be just right for the next one to fit. In the sky, ice crystals grow in layers, like stacking blocks. If it's cold enough, they form six-sided shapes because of how water molecules stick together.

Even though all snowflakes start from the same idea, ice and water, each one travels through different parts of the sky with different temperatures and humidity levels. This is like giving each snowflake its own special recipe for growing. That’s why no two snowflakes are exactly alike, just like how you might have a favorite way to build your snowman, but your friend has another.
