Water really is blue! Who knew?

Teaching bad science is not something only creationist wingnuts do. The redoubtable Bill Beaty sets us straight. (thanks, Laen)

One sunny day, Bill Beaty was walking through a car park when he noticed a black car that appeared to have a series of interesting spots and highlights on its hood. On closer inspection, he also noticed several hand prints which had a curious property: they didn't appear to be on the surface of the paintwork at all but instead looked as though they were floating several inches below the surface. In some cases they even looked like they were floating above the surface. After thinking about this he came to realize that he looking at a kind of holographic effect but this kind of hologram didn't require all the usual paraphernalia nor was it caused by light wave interference. It was a kind of holography that could be used to draw pictures in 3D by hand. (More inside...)
