Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
137 words
An educational kit for generating crystal growth comprising: a display board having at least one display face, a hollow irregularly shaped three-dimensional support, said support having a flange extending laterally from the perimeter of its hollow configuration, adhesive means for detachable adhering said support to said display face, and a plurality of items stored in the hollow configuration of said support, said items comprising a plurality of small porous rocks, at least one package of crystalizable chemical solution and a magnifying glass, whereby when the items are removed from under said support, the rocks placed on the top of said support when it rests with its flange on a flat horizontal surface, and the chemical solution poured on top of said rocks, crystal formations will occur the detail of which may be observed through the magnifying glass.
