At this website they go into detail on how life-casting is done.The company that is presenting it is EnvironMolds. They make molds that are safe from the earth and safe for ones body parts. The mold that i was looking at is one of the face. A flexible mold is needed so that it can comfortably fit on a persons face and dry and not kill the person face. The website goes into great detail on the process and everything that is needed to get this project going. it also have play by play photos. I think that this is a really cool process, for the fact that there is actually so much that goes into it. They give great techniques on how to make sure there are not any bubbles and defects in the mold. Life casting looks to be a hard thing to accomplish, but when its done its really astonishing.
