    This is rather a neat idea. The problem they were trying to tackle is how to power a liquid pump used in the diagnostics of water contamination and equipment that detects certain conditions in the blood.

    The solution, inspired by the deign of a football, was to wrap some nylon stockings round a normal balloon. This enabling you to pump up the balloon to a higher pressure. This stored energy can then be used to push liquids through a device that uses a microscope to monitor what's in the liquids.

    This should help diagnostics to be performed in remote and poor areas which would otherwise have to send of the liquids to a lab, which could be a very long way away.
