I'm having trouble finding the bat experiment that Nazi Germany did years ago. It was an experiment to show that the spirit does not exist by switching the heads of two bats. They survived for a short amount of time after the switch in which the eyes moved or something like that. Does anyone know anything about this experiment? I can't find any information about it on the web. I don't really remember what the experiment was called, but I saw it on the History Channel once about a year ago. If anyone could help me find information on it, that would be much appreciated.
