Can you keep a tin can that has not been opened in the refrigerator?

Yes, you can keep an unopened tin can in the refrigerator. Tin cans are made of steel, which is a non-reactive metal that does not corrode easily. The contents of the can are also protected by a thin layer of lacquer, which further prevents the can from rusting. As a result, unopened tin cans can be safely stored in the refrigerator for long periods of time without any risk of spoilage or contamination.
