» Was there anything Leonardo didn't invent first? Not only did he apparently develop a form of plastic, but it's environmentally-friendly to boot

The instructions in the manuscripts were clear enough to allow for an attempted reproduction of the ancient plastic by the professor's team.

"Leonardo created a material somewhere between natural and chemical plastic. Indeed, he had already synthesised a chemical very similar to acetone. But in his experiments he always used non-toxic, organic substances," Professor Vezzosi said.

"We used oil paint pigments and organic materials similar to those used by Leonardo, but you have to be patient and wait until each layer of colour dries completely. By adding vegetable fibres we got a hard and unbreakable final material."

In fact, some of the reproductions of Leonardo's plastics were very similar to Bakelite, the first entirely synthetic plastic patented in 1907 by Leo Baekeland, a Belgian chemist.

White: Witnesses said [White] walked into the pizza shop on Normandy Boulevard and allegedly said David Harrison looked like a vampire. He then allegedly shot Harrison in the face and stomach.

Police said White was heavily armed with a knife, a sawed-off shotgun and three pistols when he was taken into custody.

Palmer: But what sent Palmer over the edge was his belief that his girlfriend was in danger of becoming a vampire because Antonio Vieira bit her, Atwell said.

Palmer told him of an incident the week of the murder when he saw Antonio Vieira's image superimposed over his girlfriend's body taunting him by saying: "Ha, ha. I've bit her and now she's a member of the vampire gang. What are you going to do about that?"
