CENTRIFUGAL HOOPS



APPARATUS
rotator 202-13-A
hoop 202-13-A


DESCRIPTION
The hoop is flexible and the top is free to slide on the rod.  The circular hoop becomes oblate when spun using the hand-cranked rotator.  This can be used to illustrate the flattening of the earth's poles due to its rotation.
