5 fascinating snowflake facts
Most people know that snowflakes are unique. But did you know that snow is odorless and that snow cannot form without dust in the air? Here are five fun facts about snowflakes.
1. Snowflake world record
The largest snowflake ever measured is said to be 38 centimetres in diameter and was spotted in Montana in 1887. That's according to the Guinness Book of Records.
2. The air has to be dirty for snow to form
For snow to form, it needs a condensation nucleus around which water molecules can gather and solidify. Dust particles can be such condensation nuclei.
3. Snow on Mars is cube-shaped
Snow can also fall at night on Mars at the poles. But because the 'snow' on Mars is mainly made out of CO2, the shape of the snowflakes is cube-shaped. On Earth, snowflakes have six corners because of the structure of water molecules.
4. You can't smell snow
Snow is odorless, but many people think they can smell it. There are several explanations for this. One is that snow prevents odors from rising from the ground. So the air is unusually clear. And we can 'smell' the clean air.
5. You can preserve snowflakes
In addition to patience, superglue plays an important role. You can find tutorials on YouTube.
