Some geologists discovered a mineral in Serbia that has same chemical composition as Kryptonite, the infamous chemical in the famous Superman comic stories.

“We will have to be careful with it — we wouldn’t want to deprive Earth of its most famous superhero!,” said Dr Chris Stanley, a mineralogist at London’s Natural History Museum.

Stanley, who revealed the identity of the mysterious new mineral, discovered the match after searching the Internet for its chemical formula – sodium lithium boron silicate hydroxide.
