The lake on Hokkaido Island is a 1-0-2 tourist destination in the world. The water in the lake has different colors when looking at different angles. Specifically, varied water color varies between two shades of green and blue according to the time of year.
This special lake is an artificial product built to house a water reservoir for a dam. But changing the color of water is a surprise for the people who created it. According to scientists, the dissolved OH- aluminum molecules in the lake reflect more blue light than usual.
These rocks appear strangely in a meadow on top of Pensylvania Hill. The reason they appear is a mystery, because there aren't any high rock edges around, so they can't fall from somewhere. The sound of jingle like the sound of instruments that they emit when the force is applied is also very special.
When acting on a single stone, it emits a low frequency sound that humans cannot hear. But when put together, those frequencies resonate in the sound we hear. A lot of theories are made to explain this strange thing but no one dares to be sure about it.
The volcano of Kawah Ijen in Indonesia, flowing out of blue lava surprised many people. The reason is said to be formed on a sulfur gas field. The sulfur gas when heated and burned up to more than 5 meters, then condensed into liquid solution, flowing down into blue lines rather than really lava.
Because of that, the atmosphere here is quite poisonous, everyone approaching must wear protective masks.
