Self healing materials sound like science fiction, but how can we turn them into a reality? What does self healing even mean? We dive into the material science of self healing systems to find out what mechanism are used and how you can make a material heal. Plus we find out how you can make a self healing material out of common plastics using one of the weakest forces. Plus how scientists test and assess different materials including using....a crockmeter.
