Did you Know? Lake Karachay is stunning because it is radioactive.
According to Grunge, Russia discharged radioactive waste into Lake Karachay from 1951 to 1953.

You wouldn't be able to breathe after only one hour in its waters, such is the severity of its poisoning.
Mangoes in South India were referred to as aam-kaay in Tamil, which became maam-kaay as a result of the numerous regional dialects there.
