1. The RG Stamper Team: Sean Meek Ryan Ray Mike Higgins Steven Stokes

2. Introduction Stamp String and fasteners Two mousetraps Goal: Rube-Goldberg stamp device that uses projectile motion, conservation of energy and conservation of momentum Parts: Total cost: ~$13.75” particle board Sling shot Marbles

3. Device

4. Process 1 – Sling Shot Uses elastic potential energy Converts to potential energy Launches ball into air 2 – Funnel and tube Converts potential energy to kinetic energy Falls down tube 3 – Collision and end of tube Conserves momentum Moves up 3.25” through tube

5. Process (continued) 4 – Mouse trap triggered Tension in string Pulls string through pulley system String pulls nail out 5 – Stamper Elastic potential energy to kinetic energy Stored energy in mousetrap 6 – Paper stamped

6. Conclusion Goal reached All requirements met What we learned: Ways to adjust to group dynamics and schedules Opportunity to use concepts and theories learned in EF151
