A talk by Professor Helen Gleeson, OBE. Cavendish Professor of Physics and Head of Physics and Astronomy, University of Leeds.

This lecture was coordinated by the Hereford and Worcester centre of the IOP West Midlands branch. The lecture was aimed at those with A-level science knowledge. It was BSL interpreted.

This talk introduced what these special rubbers – liquid crystal elastomers – are and how they spontaneously change shape, can lift thousands of times their own weight, and how they can even get thicker when stretched, rather than thinner.
