ELI5: Explain Like I'm 5

Snow filtration

Okay kiddo, imagine you are playing in the snow and you eat a handful of it, but sometimes it can be dirty and not good for you.

So, just like our body has kidneys to filter out the bad stuff, we need to clean the snow too.

Scientists and engineers have made special equipment that can clean snow. It has a lot of tiny holes, like a strainer, to trap any dirt or small particles in the snow.

When the snow goes through the tiny holes, it gets filtered and the clean snow comes out on the other side.

This cleaned snow is very important because it can be used for drinking water, which is really important for staying healthy.

So, next time you see someone collecting snow, don't be surprised, they may be cleaning it for our health!
