1Q30.39  TRANSFER OF ANGULAR MOMENTUM IN A FLUID

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.
