Curious about constructions? Inside this book, you'll come face-to-face with 50 incredible structures, including: a fire-breathing octopus sculpture; the skateboard ramp you'd need to jump the Great Wall of China; a whole community of tree houses in Costa Rica; and a lifesize X-Wing Starfighter built of Legos. These and many more fascinating accounts of constructions both fantastically useful and gloriously unnecessary await inquisitive readers, aspiring engineers, and anyone who ever looked at a skyscraper and thought, "Yeah, but what if it had a roller coaster on top?."
