Alien technology in science fiction movies always has that magical material that space crafts are made of which tend to seal themselves up even as the bullets split it apart. The gaping hole slowly but surely begins to close on itself and soon there is no evidence left of the damage done by the bullets that were showered on it.

Well, it seems that scientists today have managed to figure out some of the secrets that would make it possible to become a reality on future space crafts we build. A self healing material has been developed by researchers that can prevent structural penetration from becoming a catastrophic event.

With the air supply that is required for astronauts to survive in space being a premium, this new self healing substance is obviously going to be a very important development. The material was created by sandwiching a reactive liquid between two layers of a solid polymer.

During experiments conducted by the researchers when the material was shot at with a bullet, the liquid quickly reacted with the oxygen to form a solid plug for the hole in a second. Needless to say this science experiment is going to be a closely watched one.
