When it comes to food, ignorance is sometimes bliss. Take gummy candies, for example. You likely know they’re made with gelatin—a colorless, tasteless protein that’s used as a thickening agent. But did you know that gelatin is extracted by boiling animal skin, tendons, ligaments, and bones with water?

In an episode of Flemish public broadcaster VRT’s Over Eten (On Food), Belgian filmmaker Alina Kneepkens explores how the chewable treats are manufactured, step-by-step. According to Eater, the short film is part of a series examining how various foods and ingredients—including sugar, black pudding, lamb burgers, and more—make their way from farm and/or factory to grocery store shelves.

Origin videos aren't exactly a new concept, but Kneepkens adds an interesting twist: She films the assembly process in reverse, presenting viewers with familiar foods before revealing how they’re made and what ingredients are used. Watch the video below, and be prepared to be surprised by how gross gummy bears can get.
