Self-Healing Plastics

NPR's Larry Abramson takes a look at the new technology of self-healing plastics. The technique involves filling plastic with microscopic liquid bubbles that break open to fill in the tiny cracks that occur in plastic under impact or stress. The "healed plastic" retains most of the strength found in the original. Soon, this new type of plastic may be used in products ranging from aircraft wings to the doors of your car.
