Spring in a Stapler (Elastic Potential Energy Machine)

• This stapler is my roommate's dearest treasure. It can stapler up to a "surprising" 17 pgs (if given enough for, maybe beyond that). Regardless, my roommate lets no one else us it. The spring within is currently expanded in my hand, but when the stapler folds back, the spring's energy will be converted to force used to move the staples within upward towards the dispensing end.
