Hot Air Balloon Experiment
Hot Air Balloon Experiment is a simple science experiment to teach kids about the concept of warm air and cold air. Through an easy activity, using an empty bottle, a deflated balloon and hot water, kids will learn how and why air expands when it is heated up. This concept will also help them to understand the mechanism behind hot air balloons. Kids will be introduced to a new scientific term- molecules. Adult supervision is recommended to carry out this activity.
