You can make it! World's Simplest Electric Train

World's Simplest Electric Train! The system is simple enough, you have a battery sandwiched between two polarized magnets running through a conductive loop of copper wire. As soon as the battery and the magnet assembly enter the copper tunnel, they complete a circuit and now you have current running throughout the coil as the battery and magnets induce an electromagnetic field. The copper coil forms a solenoid (length of the battery), the solenoid now has its own magnetic field that interacts with the magnets in the end. The resultant force pushes the top magnet and pulls the bottom magnet but since the solenoid is in between the magnets, it goes along with them throughout the loop repeating the process.

Fun fact: if you reverse the polarities of both magnets, you would make the "train" travel in an opposite direction. You could also accelerate the train by either having a higher voltage battery and or stronger magnets on the ends.

More:  China already have a train that uses magnetic energy to move it. And Guess it's also the safest! No derailments.

Dinka, a Wonderful Nilotic Ethnic Group from Sudan

This is an update regarding the Dinka. The Dinka are a Nilotic ethnic group from South Sudan. They live from the tenth century on both sides of the Nile River and speak a language belonging to the Nilo-Saharan group. They are about three million and are divided into about 21 groups, each with its own legitimate leader.
Although farming has always been its main economic resource, there has never missed an important agricultural and fishing activity that allowed them to be self-sufficient in food. Their trade and light industry are increasingly gaining importance.
Photographers Carol Beckwith and Angela Fisher have an experience of over 30 years recording ceremonies, rituals and daily life of African tribal peoples. His photographs reflect a long and deep relationship of respect for the customs and people of these tribes, especially those of the Dinka:

Traditionally Dinka not wear many clothes, so it is normal for a grown man to go completely naked except for collars around the neck. Women usually wear only a goatskin from the waist. Increasingly, young women are likely to adapt the dress forms from neighboring towns, and men, the long robes worn in the north. They care a lot, especially men, about body ornamentation. They usually remove some teeth by a purely cosmetic issue. Men who are pastoralists, use cow dung ash to ward off mosquitoes. It is easy to see men, especially among young people, with dyed red hair, for what they use cow urine, while women shave their head and eyebrows, leaving only a tuft of hair above her head.

Nice Cute Humming Bird

Nice Cute Humming Bird....A Must See....A Must Share

Hummingbirds are New World birds that constitute the family Trochilidae. They are among the smallest of birds, most species measuring in the 7.5–13 cm (3–5 in) range. Indeed, the smallest extant bird species is a hummingbird, the 5-cm bee hummingbird, weighing less than a U.S. penny.

They are known as hummingbirds because of the humming sound created by their beating wings which flap at high frequencies audible to humans. They hover in mid-air at rapid wing-flapping rates, typically around 50 times per second, allowing them also to fly at speeds exceeding 15 m/s (54 km/h; 34 mph), backwards.

Hummingbirds have the highest metabolism of any homeothermic animal. To conserve energy when food is scarce, and nightly when not foraging, they go into torpor, a state similar to hibernation, slowing metabolic rate to 1/15th of its normal rate. [Source: Wikipedia]
