You might be the type of person with constantly changing tastes -- or perhaps one with an assorted appetite? If you fall into either of these categories you will probably find the HydraDuo Bottle to be an incredibly clever concept. It allows you to carry two different beverages at once so you don't have to chose just one ahead of time.
Maybe you're usually in the mood for juice in the morning and tap water later in the day? This Cody Stowers creation will accommodate for that. The water bottle contains a pair of completely separate compartments which can be filled with up to 8 ounces each. The mouthpiece opens and closes as two individual latched lids so HydraDuo Bottle can hydrate a pair of people who hope to avoid sharing germs.
