Glance 3.0 by Steve Thompson

A spectator picks one of two magazines, opens it to any page and chooses a long, difficult word. They close the magazine, and you name the word without ever opening it again. Glance 3.0 comes with two ready-to-use magazines that look like ordinary store-bought copies, and the covers can be swapped for any standard-size magazine cover in under a minute. This new edition has modern covers and revised text, plus an option that spares the spectator from saying the first letter aloud. If you own the earlier versions, the word bank matches, so you can offer up to six magazines. There are no apps, batteries or Wi-Fi, no sleight of hand and no peeks, and it takes just a few minutes to learn.
