If you place a glass of water on your bedside table in the evening to have something to drink at night, you're probably familiar with the problem that comes up when others also want a drink. It's especially true if you brew tea or pour juice and soft drinks. The lid is used to keep all flies, mosquitoes, and spiders away from your glass. It also helps prevent dust from getting in, which keeps your drink fresh for a longer period of time.
