Banana Guards

[bmccasland]

Maybe the banana guard is able to dynamically adapt to various sizes of bananas....

Even the little lady finger bananas? That MUST be magic! You put your banana in, stuff it in your jersey pocket, and then and only then does it adapt to the proper size. But if I ate a tiny banana, then wanted to hold a regular banana, how does the container know the new size? Or when empty it restores itself to the original size?
