What Really Happens When You Swallow Gum

SciShow Kids

In this engaging episode of SciShow Kids, host Jessi debunks the popular playground myth that swallowed gum stays in your stomach for seven years. After accidentally swallowing a piece of gum herself, Jessi takes viewers on a scientific journey through the human digestive system to explain exactly what happens to that sticky treat. The video breaks down the composition of chewing gum, explaining how its rubber base makes it different from regular food, and uses clear animations to trace its path from the mouth to the stomach, through the intestines, and finally out of the body. Key themes explored include the anatomy of the digestive system, the difference between digestible food and indigestible materials, and the importance of critical thinking when hearing common myths. The video specifically introduces the functions of the mouth, stomach, small intestine, and large intestine in a way that is accessible for young learners. It clarifies that while the body cannot break down the rubber in gum for energy, the digestive system's muscular contractions move it along just like fiber or other waste products. This video is an excellent resource for early elementary health and science classrooms. It turns a relatable childhood anxiety—swallowing gum—into a teachable moment about human biology. Teachers can use this video to introduce the stages of digestion, discuss healthy eating habits, or launch a unit on separating scientific fact from fiction. The clear visual metaphors and energetic hosting make complex biological processes easy to visualize and understand for primary students.
