Growing Stones or Trovants are found in Romania’s Valcea County. They are rocks that grow and multiply. Trovants are made by highly-porous sand accumulations and sandstone deposits that are cemented by waters rich in calcium carbonate.

Green Flashes and Green Rays are rare optical phenomena that occur shortly after sunset or before sunrise. A green spot is visible for a short period of time above the sun, or a Green Ray shoots up from the sunset point. It is usually observed from a low altitude where there is an unobstructed view

A Gravity Hill, also known as a Magnetic Hill, Mystery Spot or Gravity Road, is a place where the layout of the surrounding land produces an optical illusion, making a slight downhill slope appear to be an uphill slope. Objects and cars, or even a river on the hill, may appear to roll uphill in

Some 100 ceramic tablets bearing inscriptions with alphabetical signs are among the artifacts found at Glozel, near Vichy in France.

To be able to freeze bubbles is such a rare experience; it’s an interesting science. Every bubble is made up of three individual layers: a thin layer of water molecules squished between two layers of soap. The innermost layer of water, which freezes at warmer temperatures than soapy water, turns to ice within the film.

A Frost Flower is created on autumn or early winter mornings when ice, in extremely thin layers, is pushed out from the stems of plants. At freezing point, the sap in the stem of plants will expand forming microscopically thin cracks. These give way under the pressure of the sap and split open. Water, which

For twenty years a mysterious handprint was visible on a Chicago fire station window. It belonged to Francis Leavy, a firefighter, who predicted his own death in 1924. On April 18, 1924, a four-storey building was going up in flames; in the battle against the inferno Francis Leavy lost his life. The very next day,
