Did you know that you can boost the volume of your smartphone’s built-in speaker simply by popping it into an empty glass? Alternatively, you could get the Hydra SmartBottle from ThinkGeek which works as a Bluetooth 2.1 speaker, an FM radio, a speakerphone, a white noise generator, an emergency light, and a party light. It has a built-in battery pack for mobile charging, a hidden compartment for your keys, a bottle opener in case you fancy drinking something a little harder… oh, and it also holds 20 ounces of liquid, if that’s your bag. Seriously, this thing has more features than a video game blog during E3.
