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

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

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

Conclusion Construction Issues: Attempted several designs Production difficulties Time constraints Discoveries: Harder then looks Rube-Goldberg devices rock
