The mysterious glowing stone in the night in Dong Nai

When brought into the dark, the 6kg heavy stone suddenly gave off a gentle blue light but the temperature did not change. Many people asked to buy for hundreds of millions but Mr. Hung did not sell.

The owner of the luminous stone is Mr. Chau Chi Hung (54 years old, living in Buu Hoa Ward, Bien Hoa City, Dong Nai).

This special stone is 3 times bigger than a regular goose egg, a smooth surface like pebbles. Mr. Hung let this stone blend with the stone pile on the porch during the past 10 years but did not know its strange phenomenon.

"On the night of the end of August 2014, I came out on a cool patio. Looking up at the pile of stones, I found green light so I ran to see. When I saw the glowing stone, I brought it into the storage room until now. " Mr. Hung said.

After that, he invited friends and scientists in Ho Chi Minh City to review and study. However, until now, the phenomenon of glowing stone still has no answer.

At first some researchers thought that the stone absorbed sunlight and glowed in the dark. However, when he left the stone in a dark room, isolated from sunlight for months, it still glowed with constant intensity.

"In addition, when using light-grained metal on the surface of a rock, sparks are fired," said the owner of the stone. When hearing the strange phenomenon, many people came to ask for hundreds of millions of dong, but he did not sell.
