This lamp runs 8 hours on just a glass of seawater


Rural areas in the Philippines with no access to electricity depend on candles, kerosene lamps or battery operated lanterns as common household light sources. But aside from being costly and inefficient, they are also dangerous to use. Now, thanks to Engr. Aisa Mijeno, a lamp that is totally safe, environmentally-friendly, and capable of emitting light on just a glass of salt water will soon brighten up these communities.

   Aisa was inspired to design the SALt lamp (SALt is a contraction of Sustainable Alternative Living) after living with the natives of Kalinga's Butbut tribe for days relying only on kerosene lamps and moonlight to do evening chores.

   So how does it work? As simple as it sounds, the lamp uses a solution of one glass of water mixed with two tablespoons of salt to provide 8 hours of light. It will even run off seawater. Oh, and did I mention that you can also charge your smartphone or tablet from the lamp?

   The device uses the same science that forms the basis of battery-making. In a typical battery, two metal electrodes are dipped into an electrolyte solution. In this case, the electrolyte is salt water. The electrode in the SALt lamp can last up to a year, depending on how often and long it is used.

   Currently in the development stage, the people behind the product aim to have the lamps mass produced later in the year. However, their main priority right now is to deliver the SALt lamps to their target communities.

Check out this insane music box powered by 2,000 marbles

The brainchild of Swedish musician Martin Molin, the Wintergartan Marble Machine , is a bizarre music box that allows the user to play tunes using a hand crank and 2,000 steel marbles. The Rube Goldberg'esque contraption features a vibraphone, bass, drums, cymbals and other instruments that play a score programmed into a 32 bar loop comprised of LEGO Technic parts. It's mesmerizing, and you can watch how they built it over here . [h/t: MailOnline ]

Oil paintings that look like watercolors

Julian Meagher is an artist from Sydney who paints watercolor effect with oil. His paintings often revolve around Australian masculinity, juxtaposed by pop-culture references. Julian has an interesting back story. He's been a full-time artist for ten years, but prior to this he worked briefly as a doctor. The first few years was tough for him, and there were times he thought he should have sticked with his original profession. "It still feels weird to say I'm an artist," he told The Sydney Morning Herald . "You say that at a dinner party and you get weird looks. People think being an artist is a romantic, alcohol and passion-filled job. But it's not, and the idea of people seeing my work still scares me." Julian is a twice recipient of the New Work Grant from the Australia Council of the Art and has held solo exhibitions across Australia, Singapore, Hong Kong, India, Miami and Los Angeles.

Hirotoshi Ito creates creepy, yet enchanting stone sculptures

When I found Hirotoshi Ito's flickr stream about four years ago, my eyes widened and my jaw dropped. I've come across some amazing sculptures before, but Hirotoshi's work is one of the most memorable I've seen.  The Japanese artist, also known as Jiyuseki, takes ordinary rocks found in a river bank near his home and adds his own bit of weird and funny alterations. He usually spends up to a month carving and decorating each of his stone pieces. As he chisels, Hirotoshi retains the original shape of the rock, then he adds accessories such as zippers, dentures, coins and other materials to complete the illusion. His creations are somewhat creepy, but they also bring laughs and smiles to the people who see them. You can learn more about Hirotoshi and his work on his  website .
