As the temperature of air increases, the air molecules move apart making the air less dense. Hot air balloons work on this concept, using lighter, heated air to lift the balloon. In this video, we demonstrate how to make a hot air balloon using a thin plastic trash bag and a few straws. When the homemade balloon is filled with warm air, it is able to lift itself into the sky.
