Double Cone and Incline

Two-sided cone object sitting on a small incline of about 15 degrees
PIRA 1J11.50

Materials: Double Sided Cone, Triangle Platform, and Level if necessary

As a double cone moves up an set of inclined rails, its center of gravity lowers. Note that this demonstration works best on a level surface, and it may be necessary to get a board and shim one end to make the surface level enough to work. Also, the apparatus has been somewhat abused and doesn't work perfectly.
