H2Oh! 7 Easy Science Experiments That Use Water

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).
