A unique water bottle that encourages shy, young kids to interact with others using colored lights that correspond to the user’s mood. With the iconic design of a see-through disk, a button is pushed to cycle through different RBG LED colors to represent several emotions. 

For many years, mood rings were a fad among kids, but while fun, they are useless for the accurate conveying of mood since the changing colors correspond to body temperature. Enter the Communi-Canteen, a water bottle that the user sets to represent their emotions at that time. By simply pressing a button that cycles through six colors that correspond to a mood, children can display their emotions to anyone who looks at the bottle. This bottle is a fun gadget for any young person but can also be used as a conversation starter for kids who have trouble expressing their emotions. It’s often hard for kids to reach out to others especially if they don’t know each other. This bottle will make that process easier. It also can be used in classrooms to help children to communicate with their teachers when they’re confused or sad.

A resin-based disk-shaped bottle printed on a form printer, the bottle has several RGB LEDs inside connected to a micro Arduino. The outside of the bottle has the names and corresponding colors of the six emotions. The Communi-Canteen itself can be easily carried with binders and notebooks and slipped into a backpack or purse because of its flat form.

A resin-based water bottle that encourages young children to interact with one another using colorful lights that correspond to one of six emotions. The bottle is shaped in the form of a flat disk that can be stacked with binders and notebooks at school.

The Communi-Canteen is a resin-based water bottle that can light up to show the user's mood and feelings. The disk-shaped bottle is embedded with RGB LEDs that are controlled by an Arduino and a breadboard. The user presses a button to cycle through the mood colors, which diffuse throughout the bottle. The Communi-Canteen is a fun gadget for any young person but could be especially helpful to kids with social issues, as it allows the world around them to understand how they are feeling. For example, a yellow light may mean “I'm confused”, prompting a teacher may to come over and talk privately to that kid if he did not want a child reluctant to talk in front of the class.
