2. Introduction
Goal: Design and build a Rube-Goldberg device that stamps a 3 cm x 3 cm piece of paper
Cost: Just under $20 dollars

3. Overview Initial Stage: Middle Stage: Final Stage: Car runs down ramp
Pulls raised side of lever downward
Middle Stage:
Ball rolls down lever and falls from ledge
Lands on stamp press
Final Stage:
Force from ball presses spring down
Paper is stamped

4. Energy Involved Car Ball Spring
Gravitational kinetic energy as car travels down ramp
Ball
Gravitational potential energy to kinetic energy
Projectile motion leads to gravitational kinetic energy
Spring
Elastic potential energy to elastic kinetic energy

5. Conclusion Construction Issues: Attempted several designs
Production difficulties
Time constraints
Discoveries:
Harder then looks
