In our digestion experiment, we mashed a banana to mimic chewing and added water for saliva. This gooey mix went into a plastic bag as our “stomach,” where we added vinegar for acid and squeezed it to represent digestion. Then, we slid the bag into tights, acting as intestines, and squeezed again to let nutrients pass through while leaving waste behind. Who knew digestion could be so entertaining (and messy)?
