Balloons connected by Tube
Two identical balloons are inflated to different diameters and connected by means of a tube. A valve controls the flow of air through the tube. When the valve is opened, air will flow from the balloon at higher pressure to the balloon at lower pressure. The lower pressure balloon will expand. The smaller balloon has the higher pressure. So, when the valve is opened, the smaller balloon pushes air into the larger balloon. It becomes smaller, and the larger balloon becomes larger. The airflow ceases when the two balloons have equal pressur
