More fun facts
- When water turns into an invisible gas and floats into the air, it is called evaporation.
- Puddles dry up faster on warm, sunny days.
- Puddles do not boil, because the ground is much cooler than 100 degrees Celsius, the boiling point of water.
- Water can evaporate from anywhere, from a falling raindrop to the ocean to a puddle on the sidewalk.
- Some springtime pools in forests last only a few weeks or months before drying up, yet frogs and salamanders lay eggs in them.

Questions kids ask
Where does the puddle water go?
It goes into the air as water vapor. Later it may turn into clouds and fall as rain again.
