water cycle experiment 3
The aim of this experiment is to make a cloud.
Warning: this experiment requires boiling water. Always take care when
boiling and handling very hot water.
You will need:
•
•
•
•
Glass jar with lid
50ml boiled water from the kettle
Aerosol can (e.g. hairspray)
Ice
What to do:
Step 1. Boil the kettle and pour about 2cm of hot boiled water into the jar. Swirl the hot water in
the jar so that it heats up the sides of the jar.
Step 2. Turn the lid of the jar upside down and rest it on top of the jar. Add several ice cubes to the
lid and leave for several seconds.
Step 3. Take it lid off and quickly squirt in some hairspray (or whatever aerosol you’re using). Don’t
add in too much hairspray/aerosol - too much and your experiment won’t work! Put the lid - with
the ice resting in it - back on top of the jar.
Step 4. Watch the cloud form inside the jar. When it is fully formed, take the lid off and watch the
cloud escape.
