Fill the jar with a small amount of hot water.
Spray a little hairspray into the jar.
Quickly cover the jar with the lid.
Place ice cubes on the lid.
Observe as a cloud forms inside the jar.
Try using different amounts of water and hairspray.
Record how quickly clouds form with different setups.
Discuss the role of condensation in cloud formation.
A small cloud will form inside the jar as the hot air condenses on the hairspray particles.

Be cautious with hot water and matches; adult supervision is recommended.
Use diagrams to explain condensation and cloud formation.
Provide a step-by-step demonstration of the experiment.
Discuss how this relates to real-world weather phenomena.
The hot air cools and condenses on particles, forming a cloud.
Yes, but hairspray works well because it has small particles.
Yes, real clouds form by condensation in the atmosphere.
