One day we were going to the local public library. On the way I picked up a snail shell that looked interesting. It was clear!
We picked up many of them. They were in the cracks in the sidewalk. And it had rained the day before or the day before that. I think the snails must have got into the cracks and then the rain stopped and so they dried out inside the cracks!
- Why are the little shells clear but the big one opaque?
- Do you know what the body is a body of?
- If they hadn’t dried up in the sidewalk cracks, how did they get there?
- And how did the shells get made clear?
