  • Patent number: 5662327
    Abstract: A board game for play by one to six players. The board game has several container baskets, and a board with a number of connected paths. Each path has discrete places upon which a basket can be moved. Some of the paths allow for uni-directional travel and some paths allow for bi-directional travel. Non-passage areas are adjacent to the connected path. The board has an entrance and an exit for players' container baskets to enter, and to exit, respectively. A number of tokens are placed on discrete areas of the non-passage areas, directly adjacent the discrete places of the paths. The tokens bear indicia of value, and are claimed by a player's basket when it lands directly adjacent a token on non-passage area.

The sleeve member has an outer wall, an inner wall, side walls joining the outer and inner wall, and end caps defining an interior chamber therein. The inner wall has air openings formed therethrough. The interior chamber is further divided into subchambers by interior dividing screen. A number of lightweight particles are contained within the subchambers of the interior chamber. When the device is placed around an inner tube with a leak, air flowing through the leak will cause the lightweight particles to be agitated, thereby providing a clear visual indication, and often an audible indication the location of the leak.
