23.5: Demonstration of Aneurysms

  • As mentioned on the previous page, the behaviour of a modelling balloon can be used to provide a simple demonstration of an aneurysm. This is shown in the series of photographs below.

    Initially, before any air is pumped into the balloon, it is completely deflated:

    As the balloon is slowly inflated, it initially has one stable radius:
