You can't play Electro-magnetic Golf according to the rules of Centrifugal Bumble-puppy.

The Director and his students stood for a short time watching a game of Centrifugal
Bumble-puppy. Twenty children were grouped in a circle round a chrome steel tower.
A ball thrown up so as to land on the platform at the top of the tower rolled down
into the interior, fell on a rapidly revolving disk, was hurled through one or other of
the numerous apertures pierced in the cylindrical casing, and had to be caught.

Mary and Lou played Centrifugal Bumble-Puppy in the garden.
