What can I use to preserve food (e.g. banana peel) for use as a prop?
I am putting together a display and I need realistic-looking food props (slightly decayed). Ideally I'd like to use real food and coat it in something that will preserve it from further decay - similar to using formaldehyde on human or animal remains.
Is this even possible with foods such as a banana peel? If so, what would be best?
