This hot air, cold air science activity is a great experiment to watch the effects of hot air and cold air on balloon.
What you will need?
- 2 containers, one filled with hot tap water and other with cold water;
- 1 balloon;
- 1 plastic bottle.
Place the balloon over the mouth of the empty plastic bottle.
