Owls and firefighters

We have a fire station in our neighbourhood so we can observe firefighters on our walking trips.  When we were talking about the purpose of water we knew that firefighters need a lot of water. But we didn’t know how they can get water in their  big tanks. So we decided to ask Otto’s mother for help. She is firefighter and she took us to water hydrant and than to fire station where we found answers to our questions.
