Miners have discovered a substance with the exact chemical composition as Kryptonite as described in Superman Returns.
Unfortunately…
The real mineral is white and harmless, says Dr Chris Stanley, a mineralogist at London’s Natural History Museum.
“I’m afraid it’s not green and it doesn’t glow either – although it will react to ultraviolet light by fluorescing a pinkish-orange,” he told BBC News.
So disappointing!
