Abstract
Abstract A device including a pair of superimposed pliable sheets that are interconnected or sealed along peripheral edges. The device includes an enclosed, liquid-containing inner chamber defined by the sealed peripheral edges and by the pair of superimposed pliable sheets. The liquid is freely movable within the chamber. At least one discrete article is suspended within the liquid, and the article is manipulatable by causing displacement of the liquid medium. Graphics are included on one of the sheets. These graphics correspond in shape to the discrete article, and that discrete article is alignable with these graphics.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
195 words
A device comprising a pair of superimposed pliable plastic sheets having a continuous seal-forming interconnection therebetween along their respective peripheral edges forming an inner, liquid-filled sealed chamber, one of said sheets constituting a top sheet and being transparent and pliable so as to be pressable toward the other sheet, at least one movable article in said chamber of a thickness less than the spacing between the uncompressed sheets so that said article is suspended for movement in said chamber, said liquid being movable by manipulating the device to cause movement of said movable article in said chamber, the position of said movable article being fixable in position by pressing said pliable top transparent sheet toward the other with the fingers to trap said article between said sheets, and graphics on said other sheet which corresponds in shape and size to said movable article and presents a readily discernible outline corresponding in size and shape to that of said movable article so that the margins of said movable article can be aligned with the margins of said graphics by manipulating said device before said sheet is pressed to trap the article when aligned with said graphics.
Claim 2
Independent Claim
195 words
A device comprising a pair of superimposed pliable plastic sheets having a continuous seal-forming interconnection therebetween along their respective peripheral edges forming an inner, liquid-filled sealed chamber, one of said sheets constituting a top sheet and being transparent and pliable so as to be pressable toward the other sheet, at least one movable article in said chamber of a thickness less than the spacing between the uncompressed sheets so that said article is suspended for movement in said chamber, said liquid being movable by manipulating the device to cause movement of said movable article in said chamber, the position of said movable article being fixable in position by pressing said pliable top transparent sheet toward the other with the fingers to trap said article between said sheets, and graphics on said other sheet which corresponds in shape and size to said movable article and presents a readily discernible outline corresponding in size and shape to that of said movable article so that the margins of said movable article can be aligned with the margins of said graphics by manipulating said device before said sheet is pressed to trap the article when aligned with said graphics.
Claim 3
Dependent Claim
44 words
The device of claim 1 wherein said other sheet presents a colored background about said graphics which are black and white so the graphics stand out from the colored background to facilitate the alignment of said movable article with the margins of the graphics.
