Why is it so chaotic and unpredictable?
In: 1
The balloon has a variable center of mass. As the balloon deflates, the center of mass changes position both due do the air leaving the balloon and the deformation of the balloon’s surface which is no longer being kept in tension due to the loss of pressure from the air inside it. This means that the forces being applied by the air exiting the balloon is can’t push direct through the center of mass making it twist and turn as it goes forward, which makes the balloon deform even more and changes the center of mass again, making it twist and deform even more.
