Duff Goldman recently uploaded a video of him attempting the Cinnamon Challenge multiple times. If you do not know what the Cinnamon Challenge is, it is when a person tries to swallow a teaspoon full of ground cinnamon within 60 seconds and without the aid of any liquid. Most people fail as it dries out the mouth so quickly, and there are thousands of Youtube videos of people attempting it. In his video, Duff also gets former Top Chef winner Michael Voltaggio to attempt the Cinnamon Challenge with him. Watch the video after the jump.
