The Material That Can Repair Itself

Duration: 02:01

Dr Richard Trask of the University of Bristol demonstrates a prototype material that's designed to repair itself when damaged.

It works similarly to the veins and arteries in our bodies.

Built within the material are tiny hollow channels which carry a yellow-coloured liquid resin.

When the material is damaged, the resin escapes and spreads around the damaged area.

Within an hour the resin will have turned hard and the repair job will be done.
