Condition :	Excellent
Principle :	Movement of masses on a rotating surface
Area of Study :	Mechanics and Astronomy
Equipment :	Rotating Air Table, Coriolis Plate for air table, Camera Supports, 1 inch steel balls, Video Camera, Plexiglas Coriolis - Overhead Projector model and Instruction Booklet.
Procedure :	Put the Coriolis plate onto the rotating air table. Assemble and mount the camera as shown making sure that the table will rotate freely. Adjustment of the camera antenna may be needed for a clear signal to the receiver. The unit does not have to rotate very fast to work well. The timers must be turned at least 1/4 turn to insure that they trigger properly. The overhead model may be used after consulting the instruction booklet in the 1E30.28 File in the Mechanics Section.
