Abstract
Abstract A hand manipulative game including specially formed fluid chamber, and specially formed objects which must be manipulated into predetermined relation to a target in the chamber. The fluid chamber is formed between a pair of spaced apart translucent walls which are in parallel relation to each other. At least one pair of balls are within the chamber with one ball having a lower specific gravity than the fluid which is to fill the chamber and the other ball having a higher specific gravity than the fluid which is to fill the chamber. The diameter of each of the balls is slightly smaller than the space between the parallel spaced apart walls. Each pair of balls is movable in the fluid chamber in a predetermined relation to the target in order to successfully complete the game.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
179 words
A hand manipulated game comprising a fluid chamber formed between a pair of spaced apart walls which are in parallel relation to each other, a body of fluid filling said chamber, target means in the fluid chamber, at least one pair of balls within the chamber, one ball having a lower specific gravity than the fluid which fills the chamber and the other ball having a higher specific gravity than the fluid which fills the chamber, the diameters of each of the balls being slightly smaller than the spacing between the parallel spaced apart walls, said pair of balls being movable in the fluid chamber into predetermined relation to the target means to successfully complete the game, said parallel spaced apart walls being translucent so that the target means and the movement of the pair of balls in the chamber are visible therethrough as the chamber is manipulated, the ball having a rolling action with respect to the walls, and the motion of the pair of balls being substantially two dimensional when viewed through the translucent spaced apart walls.
Claim 2
Dependent Claim
179 words
A hand manipulated game comprising a fluid chamber formed between a pair of spaced apart walls which are in parallel relation to each other, a body of fluid filling said chamber, target means in the fluid chamber, at least one pair of balls within the chamber, one ball having a lower specific gravity than the fluid which fills the chamber and the other ball having a higher specific gravity than the fluid which fills the chamber, the diameters of each of the balls being slightly smaller than the spacing between the parallel spaced apart walls, said pair of balls being movable in the fluid chamber into predetermined relation to the target means to successfully complete the game, said parallel spaced apart walls being translucent so that the target means and the movement of the pair of balls in the chamber are visible therethrough as the chamber is manipulated, the ball having a rolling action with respect to the walls, and the motion of the pair of balls being substantially two dimensional when viewed through the translucent spaced apart walls.
Claim 3
Dependent Claim
41 words
A hand manipulative game as defined in claim 1 wherein said target means includes a common target area within the fluid chamber, said pair of balls being movable into predetermined relation to the common target area to successfully complete the game.
Claim 4
Dependent Claim
34 words
A hand manipulative game as defined in claim 1 wherein said target means includes individual target areas for each ball, each target area including a recess in one of the parallel spaced apart walls.
Claim 5
Dependent Claim
45 words
A hand manipulative game as defined in any of claims 1, 2 or 3 including means defining one or more tracks on the inside of each of the parallel spaced apart walls for guiding balls relative to the target means as the game is manipulated.
Claim 6
Dependent Claim
55 words
A hand manipulative game as defined in claim 4 wherein the fluid which fills the chamber is water, and wherein the difference between the specific gravity of the heavier ball and the specific gravity of water is greater than the difference between the specific gravity of the lighter ball and the specific gravity of water.
Claim 7
Dependent Claim
59 words
A hand manipulative game as defined in any of claims 1, 2 or 3 wherein the fluid which fills the chamber is water, and wherein the difference between the specific gravity of the heavier ball and the specific gravity of water is greater than the difference in the specific gravity of the lighter ball and the specific gravity water.
