Magnifying glasses are great for examining ancient texts and burning ants — but if you really want to see what's going on at a small scale, grab this NPW Pocket Microscope ($42). Measuring roughly 6" x 4", this pocket-friendly tool offers sharp 30x magnification, letting you see close-up details of everything from flowers and fibers to smartphone screens and counterfeit bills. We're kidding, of course — we think.
