Memobottle Notebook-Sized Water Bottles — Tools and Toys: I loved the medium-size Memobottle, and I carried it around at work for several months. The only problem was how often I was asked with a sarcastic tone, “What are you drinking?” People assumed it was vodka because of its flask-like shape. I eventually changed to a Yeti, but I was never in a fraternity. Now I drink water out of a glass like an adult. Sigh.
