Pull water from the air

 

Water can be a gas that’s part of the air around us. You can’t see it, so how do you know it’s there? Try this.

You Will Need:

What To Do:

  1. Fill a dry glass with ice cubes and water.
  2. Go and do something else for about 15 minutes.
  3. When you come back, look at the outside of the glass
  4. Run your finger over the outside of the glass. What do you feel?

Results:

The tiny drops on the outside of the glass are water that has condensed from the air. Some of the water vapor in the air changed to liquid when it touched the cold glass. What do you think will happen if you empty the glass and let it stand? Where does the water in a puddle go when the sun comes out?
