This demonstration uses food and a series of containers and additives to model the process of mechanical and chemical digestion in the human (mammalian) digestive system. The demonstration begins with actual food items and ends with a paste closely resembling fecal matter. Due to the high “gross” factor, this demo is a hit with students and is guaranteed to be very memorable.
