You could read all about how everyday products work, but sometimes it helps to actually see it. Cut in Half: The Hidden World Inside Everyday Objects shows you what’s going on under the hood of many common items. Author Mike Warren and photographer Jonothan Woodward teamed up on this incredible project, in which Warren used a high-pressure waterjet cutter to slice through common gear and reveal its guts. From boomboxes to boxing glove, oil filters, and seashells, Warren and Woodward showcase the mysterious inner workings of these products across 144 pages in Cut in Half. The hardcover hits shelves on September 4, but you can pre-order now and clear a spot on your coffee table.
