Due to serious water pollution, lot of marine organism are dying.
To solve such problem, I represent a rock which is a combination of enjoyment and solution to the problem.
The idea of this rock came from rock skipping at rivers or seas, and different from usual rocks, this rock is compressed microorganism which can purify polluted water.
waste flowing into rivers and seas causes water pollution and ecocide.
Also, purifying the polluted water is not so simple.
The purpose of microorganism rock is to solve such problems and this can purify water while playing skipping rock.
