2. Target Audience Children 10+ interested in STEM
Something that a child could view that would promote critical thinking 
Something that would encourage the ideas of essential engineering topics i.e. statics. 

3. Customer Identification
17 year old girl
Interested in STEM
Looking for something for her desk that’s entertaining
Toy cant take up too much space
Preferably works on its own, with minimal human input
Wants it to be energy efficient to save money

4. Choosing a Toy: Initial Ideas
A robot that could preform tasks
A fidget toy
An assembly kit for metal sculptures
A perpetual motion toy

5. Final Idea A perpetual motion device was chosen Why?
Met all consumer requirements
Stress relieving properties 
Classic and simple
But still...
Thought provoking & fun
An example of pure, uninterrupted motion. 

6. Conceptual Design
Our first design idea for a perpetual motion toy used a rotating circle,  like a Ferris wheel, which would carry the marble up.
We discovered a perpetual motion device that used an auger bit instead. It was decided to abandon our initial idea; as the auger bit would be more efficient.

7. Actual Design Wooden base and backing
Plastic tubing for ball to roll through
Motorized screw for ball to go up
PVC pipe to hold screw in place
Switch to turn toy on and off

Video

9. Feedback and Results Works just as we had hoped!
Toy is efficient, compact, and visually appealing

Improvements 
Different materials for tubing, as the materials we used were very difficult to work with. Also, a different motor, the current one made it difficult to control speed
