A Persuasive Speech to Sell a New Product

How would you create a persuasive speech with the title “Sell Me a Product”?

Your speech would present a product you will be creating and designing: a phone app or gadget of your choice that is currently not in existence! This product does not have to be realistic or something that could really be made, but you will be in charge of selling it to the class in some way, shape, or form. Please note that since you are creating a product, you will need to be creative with your sources. For example, if creating an app for a cell phone, you might provide real statistics on the number of users of app-based applications or the number of people who desire photography apps based on a study you were able to find.
