Snowflakes are the wintery equivalent of a fingerprint: no two are exactly alike! These frosty wonders are formed when water vapor in the air turns into ice crystals, which can then stick to particles in the air to form a snowflake. As the snowflake falls through the sky, it can collect more water vapor, which freezes onto it and causes the snowflake to grow. The shape of a snowflake is influenced by the temperature and humidity of the air, but many other factors are still being explored and understood by scientists. So next time you catch a snowflake on your tongue, remember that you’re experiencing a tiny, one-of-a-kind work of art!
