PURPOSE: To illustrate inertia of rest.

DESCRIPTION: The felt tip end of a Pilot pen is balanced on a 12" embroidery hoop, which in turn is balanced on a Coca-Cola bottle. Yanking the hoop out from under the pen by the leading side allows the pen to fall straight downward into the Cola bottle.

SUGGESTIONS: Balancing this thing requires a good deal of practice and/or skill!!

REFERENCES: See Demonstration Reference File for further description of this demonstration.

EQUIPMENT: Cola bottle, 12" embroidery hoop, and Pilot pen,

SETUP TIME: None.
