You know the phrase “it’s just a rock”? Not this time. Rock Solid is the hilarious gift book that proves nature has a seriously rude sense of humour. Packed with real geological formations that look... well, exactly like you’re thinking, it’s a goldmine for fans of geology and giggling. A brilliant novelty gift or stocking filler for men who enjoy a bit of childish joy with their science. Once you’ve seen it, you can’t unsee it. And yes, they’re all real.
