ELI5: What does the crisper drawer in a refrigerator actually do? How does it work?
gpt
The crisper acts like a separate container keeping the mositure of the vegetables in a small area where if it was on the shelves the moisture would fill the whole refrigerator and be lost every time the door is opened. It's really nothing fancier than that. Some crispers will have a little slider or lever that opens and closes a vent to release more or less moisture.
