11. The color changing lake on Hokkaido Island
On the Hokkaido Island in Japan, there lies a spectacular lake. The lake is serene and the water is electric blue. But hold on, as soon as you change your angles of viewing the water changes color; it is dull green now. This continuously happens on the lake, even more when the seasons are changing. The lake shifts its water coloring from blue to green, back and forth.

Remarkably the lake is man-made. The locals created a dam nearby and set up an artificial lake where the water blocked by the dam would gather. Imagine their surprise when the water changed its color dramatically in a matter of seconds.
Scientists claim that this phenomena is caused by the presence of aluminum hydroxide particles that come into contact with the water.
