• When a bucket of water is rotated on a turntable, water in contact with the side of the bucket begins to move first, and the movement is slowly (a minute or two depending on speed) transferred toward the center.
  • A video camera may be needed to show the results in a large classroom.
  • This demo is a good follow up to the Waterball demo - 1Q40.46.

        (clamp the rotator to the table)
        (fill bucket half full, make sure it is seated between brackets)
        (set speed to 400 RPM)

  • Wood strips show the motion of the water slowly progressing toward the center.

  • RPM can be varied with speed control knob.  Do not exceed 400 RPM.
