The title for the 2004 competition is the Bowling Ball Drop. The objective of the challenge is to get a 10 pound [4.5 kg] bowling ball from a 1.5 meter high platform to a spring-loaded pan approximately 6 inches off of the ground and not crush an egg 2 centimeters below the pan. Our plans for the device had changed over the course of several weeks ranging from using springs to slow down the ball to a trap door above the pan. We decided to go with the trap door idea because our initial idea was not feasible considering the size of available space to work with. At the competition, we found out that we could not use our hands to push the bowling ball so that greatly altered our strategy and left us with a disqualifying entry. After last-minute improvisations, we created a legal starting motion and took 3rd place as well as Most Creative Entry.
