Drinking water from a bottle just got better with the Whistle Cap by Weiche Wu.

The bottle is a simple design that functions to quench thirsts while giving users an option to play music. Instead of unscrewing a cap each time a user reaches for a drink, the Whistle Cap is equipped with a slit on the side of the cap that allows for both drinking and whistling. This whimsical design has a dual functioning purpose. One can turn right or left to switch the drinking or whistling option; this acts as a lock to prevent water from spewing out while you whisk away playing flutey tunes.

Whether users are at a marathon, around the camp fire or walking down the street, the Whistle Cap by Weiche Wu will catch anyone's attention.
