My dad, Ed Patient made them for our school. We also have a special themometer coiled up in a thing a ma jig on the weather station. Inside this coiled house are two instruments. One is the themometer, and the other is the humity gauge. The humity gauge measures the humidity.
Humidity is the water vaper.
Water vaper is hard to see unless there is a lot in the air, then it is seen in the form of clouds. You can feel water vapor when the humidity is high. Humidity is how much water vapor there is in the air. We think water vapor is neat. This is our weather station.
