Plastinated bodies don't decompose, and museums and medical schools can display them with exposed muscles, veins and brains in exhibits around the world. One such exhibit, called "Bodies," has visited dozens of cities worldwide since it opened in 2005. Hong-Jin Sui founded the Dalian facility in 2002 after he studied plastination under the man who invented it, Gunther von Hagens. Sui says the human bodies processed at Dalian Hoffen come from medical universities and the animals from zoos and aquariums. It can take more than two years to plastinate large animals, such as whales, but humans take only eight to 12 months.
