The invention concerns an at least approximately spherical, transparent, soft, air-filled plaything, a tumble ball, which can be moved from inside and from outside and is suitable for rolling, climbing, jumping, short falls and other playful activities for the people of all ages inside it. According to the invention, the ball consists of an inner layer and outer layer, made of film-like material 1, an access opening 2, a ventilation hole 3, an air space 4 (or several such spaces), a handle 5 and valve 6. The ball is used in the following manner: one or more people go into the ball and can make it roll by moving around (by walking or rocking, etc). At the same time, people on the outside can push the ball or try to climb onto it. A similar activity is possible in water since the ball floats. The light weight of the ball makes it easy to move, and its transparency increases the motivation of the players. The light weight and transparency are also safety factors. The buckle which facilitates the manufacture and servicing of the ball can be connected to the attachment pieces 5 between the outer and inner membranes. The ball consists of one piece whose halves are pushed into each other. IMAGE
