Gross Out Popular Mechanics for Kids : Season 2 Episode 3

Eww, gross! Elisha and Tyler learn that disgusting things are useful. Tyler visits a plant where mountains of filth go through a fermentation tank and come out as animal feed. Miniature medical cameras take us on a tour of the human digestive system and we see what happens to the food we eat. And we learn how to make boogers out of sugar and protein. Yucky fun!
