When I realized I would have access to an industrial waterjet what’s the first thing that came to mind? “What fun stuff can I cut up?” of course. Starting off the list is a regular slab of rock. It’s abundant and we hadn’t tried it yet.  I scrounged a local dried up creek bed for a few prime candidates and it cuts like butter, especially considering the thickness. Check out this geology!
