Is it safe to eat snow or drink it melt?
Answer 1:

Some snow is safe to eat or drink. But a lot of snow has dirt or bacteria or other things in and on it. The snow by the street where I lived in Virginia was very dirty, and when I dried it out in a sandwich baggie, there was a lot of dirt left in the baggie. I've also seen pink snow, and I've seen pink color in toilets and bathtubs that I think is due to microbes of some sort. Google says pink snow has algae in it - Chamydomonas nivalis. Scientific American says you can get sick from eating pink snow - but not from playing in it!

When I first went backpacking in 1968, we drank water from streams. Now we don't drink water from streams without purifying it first.

Keep asking questions! You can search for answers on the internet at google.com, or you can look in Wikipedia.com on the internet - or in Simple English Wikipedia (simple.wikipedia.org). But sometimes you'll find wrong answers on the internet, too, so keep your mind open to new ideas and new answers.

Best wishes,
