Today I am writing a lecture on how open pit mines work (from a heritage management perspective). Tragically, I find this stuff really interesting - I remember, while excavating once on a Hunter Valley coal mine, one of the drillers got a bit enthusiastic about having a number of young female people around and asked us to visit his rig, quite illegal of course. I was far more interested in watching the drill bit than being chatted up, I fear!
However, there is only so much discussion of stripping ratios and NVPs that a person can take in one go, so I am distracting myself with more rocket cakes. Rocket (and satellite) cakes have become a much larger theme on this blog than I imagined was possible, but when confronted with stunning creativity, there is nothing to do but acknowledge it. So here is the rocket cake that the very creative Karen Cheng made for her son's third birthday party, and some lovely toilet-roll rockets.
