I thought the "Origin of Specious" was very clever. There were a couple of times when I read everything in the brackets and then the prezi zoomed in on parts of it. It was a bit redundant. Your example of the old woman/ young woman trick was awesome. You could even add more examples like that. Although the zooming thing at the end was a good surprise, you could have it zoom out to be something more "specious", hahah. What about a picture of a real person, or something more detailed? good job!
