NASA Creates Material That Self Heals After Getting Shot

A self healing material has been created from research that NASA funded and the substance takes only a few short seconds to fully repair. This feat is accomplished by a gel that sits in between two solid polymer sheets, once the gel is exposed to air(for example if the polymer cracks) the gel will fill in the cracks or holes and harden in a matter of seconds, thus repairing the polymer. This will most likely be used by NASA in future space crafts. This can also be used in more terrestrial items such as cars or cell phones. Image a car windshield or a cell phone screen that repairs itself after being cracked.
