I found this rock today on my property. It looks similar to another rock I saw that was said to be a civil war cannon ball, however comments below suggest that it could be a geode.
- Are there any tests I can do short of breaking it in half to find out if it is a geode?
- If I wanted to break it into two halves in a nice way (rather than smash it up into several random pieces) how might I do that?
