Plastination is a
technique patented in 1982 by Dr. Gunther von Hagens. Using this
technique, water and fat are replaced by certain plastics yielding
specimens which do not decay. Dr. von Hagens uses only donated bodies
for plastination.

Body Worlds is the first anatomical exhibition of preserved human bodies
which has been made available to the public. Since the first exhibition
in Japan in 1995, over 25 million visitors in 40 countries have seen
what is considered the world's most successful travelling exhibition.

The focus of the exhibition is to educate the public about anatomy and
the human body, its functions, diseases and physical changes.
