Science Experiments for Kids


Indoor Rain

You can create a little indoor rain in a jar with this science experiment for kids. Create indoor rain with warm, moist air that rises up and hits colder air above it.

What You'll Need:

  • Jar with lid
  • Hot water
  • Ice cubes

Step 1: Put a small amount of hot tap water in the jar.

Step 2: Place the lid upside down on top of the jar.

Step 3: Put several ice cubes inside the lid.

You will be able to observe moisture forming on the lid top inside the jar, and soon you'll see the moisture drip down like rain. Warm air can hold more moisture than cold air. When warm air in the sky hits cold air higher up, it condenses, turns into water vapor, and rains!

Why wait thousands of years for stalactites and stalagmites to form? Go to the next page to find out how you can grow them in just a few days.
