As soon as kids can reach a faucet, it seems they are drawn to splashing around in the water—much to the chagrin of your kitchen floor. Turn your little bit’s intrigue into intellect with these simple water-based science experiments for kids that you can do at home


Cloud in a Jar

What you need: A jar with a lid, 1/3 cup hot water, ice, hairspray.

How to: Pour hot water into jar. Place lid upside down on top of jar. Place a handful of ice cubes on the lid and let sit there for approximately 20 seconds. Remove the lid and quickly spray a spritz of hairspray into the jar. Replace the lid with the ice on top back onto the jar, and watch as a cloud forms inside the jar. When a good amount of condensation forms, remove the lid and watch as the cloud escapes.

How it works: Some of the warm water in the jar turns to water vapor as it rises to the top of the jar and comes into contact with cold air. Water vapor condenses as it cools and a cloud forms when the vapor has something to stick to (i.e. pollution...or hairspray).
