Science has never been so much fun! The Boy Scientist offers all the vintage appeal of Popular Mechanics's popular Boy Mechanic series combined with daring adventures in the laboratory. Taken from the turn-of-the-twentieth-century issues of Popular Mechanics magazine, these 160 experiments-based on chemistry, math, and physics-carry on the Popular Mechanics's tradition of making science engaging and entertaining. And even though technology has changed, and our knowledge of how things work has grown, the underlying scientific principles behind these activities remain sound. The projects include constructing a homemade mariner's compass; microscope without a lens; telescopic rangefinder; figuring out the height of a tall tree with the help of the sun; magnetizing watches and metal tools; crystallizing minerals in the lab; and building a simple radio transmitting set. Plus, there are thought-provoking experiments with gravity, pressure, and vacuums, and information on carrying out all these activities safely. As always in the series, charming illustrations throughout add to the nostalgic appeal. This classic collection is the perfect gift for every budding young mad scientist!
