3. Project Background – Recognizing the Opportunity  We recognize the opportunity to profit off of the ability to market and promote drinks at events by launching them to fans.  The problem we encountered was slowing down the projectile to a speed that would be safe.

4. People believe this device is best for marketing drinks What Could you see this being used for?# Entertainment8 Marketing17 Sales12 Customer Needs:  Ability keep beverage intact  Deliver object slowly  Sustainable  Compact  Self-contained  Aesthetically pleasing

5. Design Specifications  Be able to withstand a 10 foot freefall  Deliver drink to fans at 2.5 m/s or less  Prototype costs less that $10 to build  Holds a drink sample of 100 ml (3.4 fluid ounces)  Projectile must have a diameter of 3 inches or less

7. Systems Diagram

8. Concept 1  Umbrella design  Closed on flight up  Open on flight down

9. Concept 2  Umbrella/Rocket combo

10. Concept 3  Falls bottom first  Nose cone becomes parachute

11. Concept 4  Helicopter design  Inspired by maple seed

12. Concept 5  Bottle Rocket design  Bottom weighted  Octagonal parachute opens on descent

13. Design 5 was the best design choice  Pairwise comparison chart

14. Determining the Drag Coefficient  Dropped from 5’ 11” (1.8 m)  Multiple trials with multiple layers of trash bags  Use drag coefficient to determine parachute area

15. Calculations To determine area of parachute. To determine side length of octagonal parachute. Free body diagram at terminal velocity.
