Spray-on Skin Gun

I remember Will Smith in I, Robot, spraying his bionic arm with some sort of instant skin to cover up the damage, and this time round we have something out of the world of science fiction that could be a reality. The spray-on Skin Gun could be the result of a $250 million research project that sprays new, stem-cell infused skin onto a wound to expedite the healing process to just hours (minutes are still an unrealistic target). Well, it might not be Wolverine’s healing factor but at the very least it is better than waiting for a week for it to heal.
