Make Rain Indoors

What You Need:

• An empty glass jar with a metal top
• Hot tap water
• Ice cubes


Tip: Be patient. It takes about 15 minutes for water drops to form.


Question: How can you make it rain indoors?

1) First, fill a glass jar with very hot tap water.

2) Then, flip the lid over and fill it with ice. Place the lid on top of the jar .

3) Now, wait and watch. In about 15 minutes you will see "rain" fall inside the jar .


A Scientific Explanation:

Some of the hot water turns into steam and collects on the lid. The ice cools the steam and turns it back into a liquid. When enough liquid collects on the lid it falls as a "rain" drop. This process is known as condensation.


EXTRA! EXTRA!

Look for other examples of condensation such as water drops forming on the side of a cold soft drink can. Use what you’ve learned about condensation to explain your observations.
