Our Assignment
Our assignment for this project was to choose a world problem from a list of world problems to try to find a solution for. Our class came up with many world problems including but not limited to; world hunger, infustructure, and global warming. Our group chose a simple but very frustrating problem in tangled headphones. We were required to research the problem using reliable sources, design a prototype for our design, and be prepared to present all of the data and the prototype to the class by the end of the project.

Here is this research that we conducted for our project:
There are multiple copper wires in each headphone wire. There is one for each component of the headphones including each earbud, the microphone, and the ground. The ground wire completes the circuit between all of the wires and the headphone jack that leads into the phone.
Each wire is coated with a protective layer of enamel that keeps the wire from stripping and protects against damage to the individual wires.
Some liquid plastics are a good material for the outer shell of the headphones. Plasti dip is a strong material the starts as a liquid and hardens over a short amount of time. Although this plastic hardens, it always remains flexible and stretchy for its entire lifetime. It also will not break or become brittle even in extreme conditions.
100 feet of shrinkable plastic wrap is available for only $7.96. Premium 14/2 Awg 100-Feet CL2 Speaker Wire Cable - Oxygen Free Copper is available for $34.99. A headphone jack is available for $2.13.

Reflection
This project definetly left an element of creativity for our group to pick from a large variety of world problems and figure out a new and creative way to solve the problem.
