Lightning Helps Create Aritifical Blood Vessels

When an electrically charged block of plastic is struck with a nail lightning bolts tunnel through creating a template upon which artifical blood vessels could grow. The tunnels, which resemble capilaries, could be used to grow new arteries and veins for a person, or to help scientists grow organs in a laboratory setting. Cool!
