FunctionThis instrument is to demonstrate the properties of the center of gravity. When the top of the tower is off, the tower stands erect. When the top is added on, the tower falls on its side. Putting the top on the tower displaces the center of gravity of the whole tower towards the top, beyond the edge of the base. This shift destabilizes the tower and makes it fall.
