Join "Hard Hat Harry"--the construction worker's genie--and his young friends, Max and Alex, as they travel to major construction sites to see massive machinery in action. You'll see more than 25 pieces of giant construction equipment on the job, including colossal cranes, bruising bulldozers, dirty dump trucks, powerful pavers and so much more. Kids get a close-up look at earth movers digging tons of dirt, skyscrapers and roads being built, stone mountains being blown to bits by dynamite, even monster machines that magically introduce themselves and explain exactly how they work.
