Reading in the Shower Though many smartphones and tablets have some degree of water resistance, I prefer not to expose my electronics to splashes, soaps, and salty water. For learning in the shower, I've found three successful methods: Phone in a self-sealing plastic bag. Cassette player or speaker in a disposable shopping bag. Laser-printed pages adhered to the shower walls. For (1), the touchscreen is mostly usable even with some water droplets outside the plastic bag. For (2) I find that the thinner the bag the better for sound quality - including enough air that the bag is partially limp, partially inflated will also improve the sound. For (3), it's essential that the pages be printed with toner, not ink. Gently wet the pages with shower spray and then place them against a wet section of the shower wall. They will stay attached for up to a week (for fiberglass and tile).
