Hi sorry to bother you chaps again as I mentioned before We were woken a couple of months ago with load bang and next morning discovered hole in fence mystery? Well now I'm more determined than ever and ive found a new rock it has a strange reverse effect when a magnet is put near you can feel it trying to push the magnet away and when I did the rub test it took porcelain off the bootom of till left no mark it is also a little bit irrediscent when you look at the black possible crust rock looks like coal but isn't its very hard and left a silver/grey inside when I cut a corner back again please your honest opinions thanks
