"Dehydrated" food that is still moist enough to be "very sticky" can be dangerous if not kept cool. -aj

First, I over dehydrate.  Because of my schedule I have been known to leave stuff in the dehydrator for days at a time.  It just continues to dry and continues to dry.

So, I would normally agree, but watermellon is different.  It ends up with a cotton candy texture. The moisture in your hands makes it sticky.  Or maybe it is just sticky.  

It kind of reminds me of corn surup.  Corn surup is sticking and you can't dry it.  It is also so sweet that bacteria will not grow in it.
