If we were to burn NH4Cr2O7 with HgSCN in the Dark Ages in Europe and show it to anyone, it is us who would be burning next on a fiery cross of Inquisition. And it’s no wonder, since this experiment produces a truly marvelous result. At first, as you ignite the mixture of NH4Cr2O7 and HgSCN, all you can see is that it is slowly burning with a reddish flame. After a while, however, a crater is formed in the middle of the burning pile, and then, suddenly, tentacle-like appendages start sprouting from the burning mixture. And you can almost hear the scream of the mad occultist – “Come forth, Kraken! Come forth!” But of course, this is simply a chemical reaction that is called the "Pharoah's Serpent". It was also often sold in firework stores until people realized that it was toxic.

Each day as we look in the mirror, we think that we know ourselves. We are used to the image that we see before us, but the mirror can show us much more than we ever hoped to see. Sometimes it only shows basic emotions, while at other times it can highlight the deepest crevices of our soul. If you wish, in the reflection of the mirror you can see your deepest thoughts, masks that you wear every day, your desires, and of course the people that you think about. But are you brave enough to look deep within your soul? Will you dive headlong or shy away from your true image? Those that will muster up the courage necessary will realize it was well worth the effort. (Photo by Devin Mitchell)

A photographer has weathered some of Americas most violent storms to capture these stunning snaps. Storm chaser Mike Mezeul II, 30, has travelled all over the US to shoot the likes of mammoth thunderstorms and surreal cloud patterns. His incredible collection of storm images are the result of more than 15 years of photography and thousands of miles of travel. The photographer, from Frisco in Texas, USA, became interested in storm chasing aged 16 when he got his first car. He has since shot ferocious storms as far north as the Canadian border and as far south as Mexico. (Photo by Caters News)

Modern art is truly fascinating. Not in a way that it produces some novel things that will fascinate future generations for decades and even centuries to come. No, that is very far from the truth. On the contrary, modern art is essentially anything (yes, any little thing) that is a bit unusual and was created by a famous person. Let’s take the creation of Antoine Bridier-Nahmias for example. His brainchild is a set of pictures of petri dishes that were contaminated by various cultures of fungi. If this is art, I missed my chance of becoming famous when I accidentally left a piece of bread in a bag in a cupboard for about six months, and didn’t take a picture of the rather shocking results that awaited me when I finally discovered it.

Nepalese women performs ritual as they take a holy bath in the Bagmati River, during the Rishi Panchami festival, in Kathmandu, Nepal September 18, 2015. Rishi Panchami is observed on the last day of Teej when women worship Sapta Rishi (Seven Saints) to ask for forgiveness for sins committed during their menstrual periods throughout the year. The Hindu religion considers menstruation as a representation of impurity and women are prohibited from taking part in religious practices during their monthly menstruations.

Roza Khamitova was born into a family of artists in Kazakhstan. After finishing design school in Manhattan, New York, she was working in fashion industry for about 8 years. As a visual artist Roza had always drawn most of her inspiration from the natural world around her in the mountains of Kazakhstan. In 2011 she launched Shovava, her personal line of women’s clothing based on her hand drawn paintings and prints of the animals, plants and patterns found in nature. Roza was enchanted by the beauty of wings, its structure and symbolism. First, she sketches big wide-spread wings on paper with a light pencil, adds black ink to create a three-dimensional feel and fills with stunning watercolors.

An environmental activist performs during a protest in front of the headquarters of Brazilian mining company Vale SA in downtown Rio de Janeiro, Brazil, November 16, 2015. The collapse of two dams at a Brazilian mine, owned by Vale SA and BHP Billiton Ltd, has cut off drinking water for quarter of a million people and saturated waterways downstream with dense orange sediment that could wreck the ecosystem for years to come. Nine people were killed, 19 are still listed as missing and 500 people were displaced from their homes when the dams burst at an iron ore mine in southeastern Brazil on November 5.

In this June 29, 2015 photo, forlorn buildings are seen at Hashima Island, commonly known as Gunkanjima, which means “Battleship Island”, off Nagasaki, Nagasaki Prefecture, southern Japan. The island is one of 23 old industrial facilities seeking UNESCO's recognition as world heritage “Sites of Japan's Meiji Industrial Revolution” meant to illustrate Japan's rapid transformation from a feudal farming society into an industrial power at the end of the 19th century. UNESCO's World Heritage Committee is expected to approve the proposal during a meeting being held in Bonn, Germany, through July 9. (Photo by Eugene Hoshiko/AP Photo)
