DESCRIPTION OF THE PREFERRED EMBODIMENTS Two bottles may be of the same shape or of different shapes.

The cylindrical member is formed as a single member or as a composite member composed of a plurality of constituent members. When formed as a single member, mounting portions that can be mounted on both ends of the cylindrical member so as to cover the outer periphery of the cylindrical mouth of the bottle are formed. When formed as a composite member, it is composed of a tubular member and two connecting members that connect both ends of the tubular member and the mouth of the bottle. When the mounting portion is formed at one end of the tubular member, it is composed of the tubular member and one connecting member. For example, a thread groove corresponding to a thread formed on the outer peripheral surface of the mouth of the bottle is formed in the mounting portion. The connecting portion between the tubular member and the connecting member is also formed with a thread, a screw groove, and the like that fit together.

A disk member having at least two holes and partitioning the cylindrical member in the diametrical direction is disposed inside the cylindrical member. When at least one of the at least two holes acts as a liquid outflow hole, the other holes are configured to act as air bubble generation holes. For example, each hole has a narrowed tip, with the tip of at least one hole pointing in the opposite direction. In particular, a hole having a tubular portion communicating with each hole and having a configuration in which the hole diameter at the tip is narrowed is preferable. If at least two such holes are formed, the direction of flow of a fluid such as gas or liquid is directed toward the narrowed tip of each hole, and these holes can be referred to as nozzles. Therefore, when the liquid flows out of at least one hole, bubbles are generated in the liquid from the narrowed end of the other hole.

The cylindrical member and the disk member may be formed integrally.

By providing the disc member with a hole that opens in only one direction, the drop speed of the liquid in the upper bottle increases in the direction in which the hole opens. Such a disc member, when two bottles are connected so that a game can be played with only one bottle, slows down the liquid drop speed of the bottle with the game and prolongs the bubble generation time. Further, it is possible to increase the falling speed of the liquid in the bottle not playing, thereby shortening the waiting time for playing again, that is, the time required for resetting.

The cylindrical member has a length that can be grasped by hand, and the disc member is disposed at least at one end thereof, and an appropriate amount of liquid is filled in a bottle. Hold the cylindrical member,
Take a muscle-strengthening posture, such as reaching out, and move the liquid from one bottle to the other,
By holding the bubble while it is generated, it can be used as a dumbbell having a timer function.

If the cylindrical member is formed of a cylindrical member, and both ends of the cylindrical member and two mounting members for mounting and fixing the bottle, the two bottles are symmetrical even if they have a long cylindrical portion. It is preferable because it can be connected to.

By inserting the decorative member into at least one of the bottles, the value as a playground equipment, a timer, and a decorative article can be increased. As the decorative member, those having a tree shape, a umbrella shape, a spiral shape, or the like having a branch that can be inserted from the mouth of the bottle and have a branch that spreads inside the bottle are preferable.

It is preferable that the disk member has a support for holding the decorative member, since the decorative member can be fixed.

The sphere 24 falls by its own weight into the tip 16S of the hole 16 of the cylindrical portion 16T communicating with the hole 16 of the first disk 13,
The hole 16 is closed by the sphere 24.

Therefore, the water filled in the bottle 1 is
The water passes through the hole 15 of the disc 13 from the small-diameter hole 15S at the tip thereof to form a water droplet 45, and transfers to the bottle 2. At the same time, the air in the bottle 2 is released from the small-diameter hole 1
The air bubbles 47 are transferred from the 4S into the water of the bottle 1. Bubbles 47 rise in the water. The small sphere 37 placed in the bottle 1 rises together with the bubble 47. The tip of the pole 31 inserted into the bottle 1 and the receiving portion 35 attached to the branch thereof face upward, and the small sphere 3 rising with the bubble 47
