Abstract
An arrangement (100) for underwater activities includes a reservoir (101), which reservoir includes a wall (102) securing a space inside the reservoir (101) to be filled at least partially with water (103). The arrangement has also an opening (104a, 104b) for entering the reservoir, and a container (105) to be filled at least partially with water (103). The container receives the reservoir (101) so that the lower portion of the reservoir including at least one opening (104a) is located under the water surface level (103). The lower portion of the reservoir when introduced with the container is securing together with the container's (105) wall an upper portion (107) of the container, which upper portion (107) supports via the opening (104a) the pressure difference between the upper portion (107) of the container (105) and the space inside the reservoir (101), when water (103) is introduced into the space inside the reservoir.
