Abstract

Abstract An amusement device including at least partially transparent container formed of non-magnetic material having a plurality of relatively small magnetizable elements enclosed therein; each of such magnetizable elements having been coated with at least one of a plurality of bright colored paints. Preferably, each of such magnetizable elements is a segment cut from a length of conventional magnetic recording tape. Alternatively, however, each of such magnetizable elements may be a readily commercially available, conventional, small ''''ring core'''' element formed of magnetizable iron oxide manufactured for use in a data storage or ''''memory'''' component of an electronic computer. A conventional bar magnet is manually maneuverable externally around and about such container, and such magnetizable elements enclosed therein may move about under the influence of such magnet to pile up, spread out, flip, and tumble to create variously colored patterns thereof in a somewhat kaleidoscopic fashion considered to be interesting and amusing.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 99 words
An amusement device, comprising: an at least partially transparent container formed of a nonmagnetic material; and a plurality of substantially small, substantially light, variously colored magnetizable elements operationally enclosed within said container, each of said magnetizable elements being a segment of magnetic recording tape having a surface coated with one of a plurality of coating materialS each of a different color, said magnetizable elements being adapted to move about within said container to form various patterns thereof in various color combinations under the influence of the magnetic field of a magnet adapted to be maneuvered exteriorly about said container.
Claim 2
Dependent Claim 99 words
An amusement device, comprising: an at least partially transparent container formed of a nonmagnetic material; and a plurality of substantially small, substantially light, variously colored magnetizable elements operationally enclosed within said container, each of said magnetizable elements being a segment of magnetic recording tape having a surface coated with one of a plurality of coating materialS each of a different color, said magnetizable elements being adapted to move about within said container to form various patterns thereof in various color combinations under the influence of the magnetic field of a magnet adapted to be maneuvered exteriorly about said container.
Claim 3
Dependent Claim 26 words
The amusement device according to claim 1, wherein each of said magnetizable elements further has another surface coated with another of said plurality of coating materials.
