Making Self Healing Materials

Whenever we cut ourselves on any sharp object it is usually quite unpleasant, but as long as the cut is minor we don't worry about it too much because we know it will soon be healed. 

The same can not be said for our things. If your car tire gets a minor cut it will be unusable until someone repairs the cut with a patch of some sort. 

If the paint on your car gets a deep scratch, it will allow water to penetrate and will eventually lead to more damage. 

What if we had rubber tires and paint that could heal themselves? What about self healing plastics? 

Well, scientists have been working on all three of these and more!
