Variable Speed Rotator
This variable-speed motor rotates up to 3,500 rpm. A central chuck with wing-nut supports various demonstration equipment, such as a color wheel (not included). The digital display shows RPM or Hertz. Uses 115 VAC 60 Hz. Suggested use: Spin a Color Wheel (P/N 614-0240) and use our Digital Stroboscope (P/N 50-005) to "Stop the Motion" of the wheel.

Centripetal Force Kit.
This PSSC-designed kit can be used to show the effect of mass, radius and velocity on the centripetal force of a rotating body. The experiment uses the weight of one to 20 1g masses from one end of a cord as a counterweight to the pull of a rubber weight swinging in a circle overhead. Includes handle, sturdy cord, rubber weight, masses (20) and instructions.

Centripetal Force Paradox. (Fish Bobber Acceleration).
Similar to the rotating candle experiment, this illustrates centripetal force in an way that "goes against the grain". Ask your students what they expect the floats to do when the platform on which they sit is spun. Our two floats serve as buoyant pendulums inside transparent jars filled with water. Since they are buoyant, they move in the same direction as the accelerating force - which is toward the axis of rotation, or toward the center....

Greek Waiter's Tray.
The waiters in Greek cafes are famous for their dexterity as they swing heavily loaded trays between tables with nary a spill. This sturdy device illustrates the principle in a way that will amaze your class. Place a clear container of colored water on the platform of the tray and start swinging from side to side. With practice, you should be able to swing in wide circles and even upside down. The container stays put because the net force...

Rotating Candle Apparatus.
A great way to understand centripetal force and centrifugal force. Why do the flames turn in instead of out when spun on the rotator?
