A magnetically operated rotative amusement device or unit of a substantially self-starting nature has a see-through or transparent container or bowl-like support base provided with a lower, centrally disposed, pivot-receiving socket. A spinner has a pivot pin adapted to rest in the socket and to extend upwardly towards an open mouth portion of the support base. The support base has either an inner collar or a relatively narrow bowl to support the spinner in an upright, slightly tilted position in a ready-to-operate relation therein. A dome-shaped lid is used to close-off an open mouth portion of the support base and has a centrally, downwardly extending, permanent magnet supported in a vertically adjustable relation in which it is slightly spaced from and aligned with a second and opposing magnet carried by an upper end of the spinner. The spinner may be caused to rotate or spin by moving the lid in an angular relation to a closing-off position from a side of the bowl that is opposite to a tilted positioning of the spinner within the bowl. If the lid is in place or in a permanently mounted position with respect to the bowl, then spinning movement may be effected by slightly tilting the support base. Rotation of the spinner thus accomplished will continue for an effective period of approximately two or three minutes using a pivot pin on the spinner part and the socket therefor of a relatively hard and smooth material of minimized frictional resistance, for example, a tapered-end steel pivot pin and a socket of glass.
