105. Why does a balloon collapse without air inside it while a vacuum bell jar does not?
A balloon's skin is too weak to support the air around it. If you don't put any gas inside the balloon, the atmosphere around it will push it inward and it will collapse. But a vacuum bell jar is made of an extremely strong plastic that easily supports the weight of the atmosphere on top of it. Even with nothing inside it, it remains full size.
