World's first rotational-gravity puzzles based on a cubic structure. This puzzle is filled with water.

This puzzle is based on the Cubedron Classic puzzle concept. It is the first ever non-dexterity mathematical puzzle which uses water. The puzzle consists of a clear plastic sphere with five white pyramids inside, which form a cube with one pyramid missing. Unlike the Cubedron, the sphere is filled with water, creating an interesting visual effect and smooth movement. The puzzle is solved when the external sides of the pyramids form a Medusa jelly fish. This is done when the tentacles are properly connected to the body of the jellyfish. There are many ways to solve this puzzle, and there are many solutions.

To flip a pyramid, ensure the empty space is always at the bottom, then move one pyramid towards the empty space, and so on. The movement should be slow enough to allow the last moving pyramid to settle properly (and "lock" with the other pyramids) before moving the next. It symbolizes the small and smooth movement of the Medusa jellyfish when swimming inside the sea.

A combination of systematic approaches is required to find one of the solutions. There are some unexpected mathematical problems involving parity and rotations. The solver is required to have intuitive mathematical thinking, balancing skills, and to spend some time to become familiar with the slow and smooth movement.

This puzzle attended the design competition during IPP29 in 2009.
This puzzle is planned to be mass produced in the future.
