Make a cloud in a glass

Clouds in the real world form in warm, moist air. You can make something similar happen using things you can find around your home.

What you will need:

glass, ice and foil dish

 

 

 

 

A clear glass or similar see-through container
Warm water
Ice
Metal or foil dish

What to do:

  1. Place the ice into the metal dish.
  2. Pour a small amount of warm water into the bottom of the glass.
  3. Wait until the dish is really cold. Then place it on top of the glass.
  4. Watch the inside carefully. You should see a ‘cloud’ form near the top of the glass.

This is the way clouds form in the real world. Warm, moist air like that in your glass, is cooled (your ice). When it is cooled it condenses into tiny water droplets, which appear as clouds.
