Easy Water Activities for Kids

Feeling Pressured?

Test the pressure between air and water in "Feeling Pressured?" You may not feel it, but the air around you has pressure. This easy activity for kids will help demonstrate its invisible force.

What You'll Need:

  • Cup
  • Index card

How to Do Feeling Pressured?:

Step 1: Fill a cup all the way to the top with water. Place an index card over the top of the cup.

Step 2: Hold the card in place, and turn the cup upside down. Slowly, carefully, let go of the index card. It should stay in place, held by the pressure of the air beneath it. Be sure to work over a sink in case your cup slips and the water spills.
