Look like a "ball" of twine to me, might of been used to string out a fence line to make it straight or any number of other reasons the farmer needed twine for.
I opened the right image. This item is about the length of a person's leg based on the person standing next to it. If it may be of value, non-destructive testing would be advised. Weigh it to get a rough idea of composition i.e. metal or non-metal or run a metal detector across it. Otherwise, the only other option is to carefully open it up and see!
It only takes a minute to snip a short piece of the winding material off and examine it under a jewelers loop or microscope. The blue piece in the middle can be examined the same way by removing a very small shaving and viewing it the same way. Probably not a stick of dynamite.
Caveat: Beware of explosive and hazmat possibilities.
I'm not sure what the winding is made of, but the way it is wound reminded me of times I have found pieces of fence wire or baling twine in a field and to carry it and dispose of it I have wound it around whatever was handy - a piece of wood or a plastic bottle.
I'm leaning towards Retired Sarges comment of a bottle wrapped to keep it from being broken. I think I remember seeing something similar to this years back !

I would tend to agree! However...
The size of the object can be estimated by the right image (click to open) with a person standing near it. This object is about 3-4 feet in length.
