Have you heard of a process called PLASTINATION? It’s a method of preserving an entire human body! You may have heard about the Body Worlds 2 exhibit recently at the Ontario Science Centre. Over 200 real human specimens were brought in from Germany and displayed in Toronto. What’s really cool is each of the human body plastinates (check out the one on this page!) is posed in different positions, so you get an in-depth look at how our muscles and body systems work.
