Custom Lid for Resealing Canned Food

There isn't really a good way to reseal canned food. I usually just end up covering the opening with a sandwich bag and a rubber band. To solve this problem I made a custom silicone lid that perfectly fits a can. I took some silicone putty and covered the top of a can. When it cured, the inside was the exact shape of a can. Now, I can use it to make a tight seal around a can. This helps to keep the contents fresh for a few extra days in the fridge.
