Eurostar, the company that runs passenger trains through the Channel tunnel between London and Paris, said it would buy seven additional e320 trains from Siemens for about 300 million pounds ($473 million). The company placed an order for 10 new trains in 2010, the first of which is due to enter commercial service next year, enabling the company to add new routes. (Photo by Andrew Winning/Reuters)

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.

Few things are more beautiful than puffy white clouds floating in the bright blue sky. Do you remember the time when you would lay on the soft green grass, look up at the sky, and try to recognize shapes in the clouds floating overhead? Wasn’t it wonderful, just lying there, letting the wind caress your skin, as you imagine that the clouds in the sky are actually mystical or not-so-mystical creatures? Dragons, ducks, teddy bears, dinosaurs, everything was up there. It was good old times. As adults we forget about simple pleasures of life. However, an Argentinian artist Martin Feijoo didn’t forget those times, and took them a step further. After imagining what a particular cloud looks like, he draws that particular shape over the picture of the cloud, allowing the entire world to see what goes on in his mind. (Photo by Martin Feijoo)

As you look at the majestic Crater Lake, located in south-central Oregon, United States, it is hard to imagine that thousands of years ago this place was one giant crater with scorching hot lava spilling over the sides. Those were the times of turmoil. Now, however, this place is the essence of tranquility. The lake that was formed, after the volcano died down, is amazingly clear due to the fact that the water isn’t moving at all. No rivers go in or out of the Crater Lake, and the water lost through evaporation is compensated by the rain and snowfall. This lake is also frighteningly deep – 1,943 feet (592 m) at its deepest point – making it the deepest lake in the United States. If you love nature and if you ever come to Oregon, this is truly a sight to behold.

When you gaze into the eyes of this beautiful creature, you can almost make out constellations forming deep within. The name of this magnificent bird is Zeus, named after the Greek god of the sky for her one-of-a-kind eyes. The reason why she has such eyes is because she is blind. She was saved by a family in Southern California, when they found her injured on their front porch. After realizing that this poor creature is blind and unable to take care of itself, they took her to an animal hospital. After she healed up, everyone agreed that she should be sent to the Wildlife Learning Center. From that point on, Zeus has been happily living in the center. And though she cannot see, you can bet that her other senses are ten times as sharp. (Photo by Wildlife Learning Center)
