Abstract

A ball drop system is used to provide a visual indication and/or verification that a ball has been dropped from the ball drop system. The system includes a ball stack including a plurality of balls and a weighted member disposed on top of the balls. The system also includes a ball stack indicator including an inner magnet disposed within a tubular member and an outer magnet secured to an outer surface of the tubular member by a magnetic attraction to the inner magnet, the inner magnet being connected to the weighted member by a cable member.
