2. Overview 1. Starts with marble rolling down a ramp 2. Marble falls into declined tube 3. Marble rolls across pivoting arm 4. Rolls down declined ramp 5. Triggers switch 6. Turns on motor 7. Second Marble falls from motor platform 8. Falls into funnel 9. Drops onto car track 10. Falls onto mouse trap 11. Mouse trap snaps pulling the tab on a “soda” can 12. Can opens 13. Enjoy a refreshing “soda”

Issues Finding a time that was convenient for everyone to meet Finding a time that was convenient for everyone to meet Figuring out how to trigger the motor Figuring out how to trigger the motor Project was over the 1 cubic meter limit Project was over the 1 cubic meter limit Mouse trap was too powerful Mouse trap was too powerful Soda lid couldn’t withstand the force from the mouse trap Soda lid couldn’t withstand the force from the mouse trap Engine’s power supply broke day of presentation Engine’s power supply broke day of presentation

5. Conclusions Despite the many problems encountered we were successful in our attempt to open a can. Despite the many problems encountered we were successful in our attempt to open a can. This showed many engineering concepts. This showed many engineering concepts. Providing increase in budget we would have had the resources to provide for easier assembly.
