Clouds need a few things to form— warm and moist air, a cooling process and a cloud condensation nucleus.
A simple speck of dust could be a cloud condensation nuclei but in this experiment it is the tiny particles of hairspray.
Meteorologist Reece Cole visited Mrs. Boyle's 3rd-grade science classrooms at Martin Public Schools to show the students how clouds develop. You can watch the science experiment in the video above!
Looking to try this at home? Here's what you'll need:
1. Glass/Clear jar
2. Hot/steaming water
3. Ice cubes
4. Hairspray
Here's what to do:
Step 1: Pour the hot water into the clear jar.
Step 2: Quickly spray some hairspray directly into the jar and put the lid on the jar.
Step 3: Put a few ice cubes on the lid, and watch the cloud get thicker and thicker in the top half of the jar!
Warm water evaporating to the top of the jar will start to cool as it touches to the lid with ice cubes. This will help the water vapor to condensate, and as it hits the hairspray in the can it will form a cloud!
