Plastic, heal thyself

Surfing around on the net, and this artical caught my eye. A polymer, (plastic to us layman's) that is able to fix or heal it self. The way this work is by having an underlining layer of vessels that have the healing liquid in them. So if an area was damaged the liquid is released and the healing process begins similar to our own skin. This has very far reaching quality's to it. imagine cars fixing dents and scratches, planes fixing holes in the wing, the shuttle able to fix it's own thermal coating, or even a house that is able to fix it's own walls when you punch a hole in it :). The application to everyday us may be several years off, but the implications are mind boggling. Just think, next time you cut your favorite pair of jeans or shirt, it could fix it self.
