The double cone ascending an inclined V-rail is a common exhibit used for demonstrating concepts related to centre of mass in introductory physics courses (see http://www.physics.ncsu.edu/pira/). While the conceptual explanation is well known-the widening of the ramp allows the centre of mass of the cone to drop, overbalancing the increase in altitude due to the inclination of the ramp-there remains rich physical content waiting to be extracted through deeper exploration. Such an investigation seems to be absent from the literature. This paper seeks to remedy the omission.
