How To Make Edible Water Bottles

How To Make Edible Water Bottles
The United States uses about 50 billion plastic water bottles each year, which requires 17 million barrels of oil. Sadly, less than a quarter of that plastic will get recycled. If you don’t want to be stuck carrying around a water bottle when you’re done taking a drink, why not just make a container you can eat? Yuka Yoneda from Inhabitat gives a demonstration of how to do just that using a process called spherification, which creates a liquid with a soft membrane that you can eat. The process combines drinking water with sodium alginate, which comes from brown seaweed. After those two are combined, spoonfuls are put into a bath of calcium lactate, which is a salt that can be found in many items like baking powder, antacids, and cheese. Want to experiment with other liquids? [Hat tip: Yuka Yoneda, Inhabitat]

A Portable Desk Made Of Recycled Cardboard, Doubles As A Book Bag There are certain luxuries that are simply not available for many school children in India. One example is a desk. Without a desk to write on, they are forced to sit and write on hard floors. Other than being uncomfortable, sitting on the floor with their backs hunched also leads to several health problems such as bad eyesight and posture. To tackle the problem, New Bombay-based not-for-profit organization Aarambh has designed an eco-friendly portable desk that also doubles as a book bag for the children. Made from discarded cardboard, it features a stencil design that can be conveniently folded into a briefcase-like school bag for the children to keep their books and belongings.

Artist paints immersive classroom murals with mud Earth's soils not only sustains all living things with its bounty, those same soils can also inspire us with its beauty. Humans have built homes with earth's soils for thousands of years, made pottery, and have even painted with earth. Working with Tokyo non-profit Wall Art Project, which brings art into schools in India, Tibet and elsewhere, Japanese artist Yusuke Asai created these stunning murals for the Niranjana School in Bahar, in the eastern state of Bihar, India. ATTiny based Electronic Candle Our friend Pete Mills developed this great ATTiny based Electronic Candle, we have seen electronic candles before but what makes this one shine is how the flickering was done. Pete actually sampled the actual flicker patterns of a real candle flame so that this reproduced flame would look as close to the real thing as possible. You can see some other electronic candle designs here for inspiration. “The ATTiny Candle is an LED candle. It uses a high brightness LED and some software to mimic the look of a traditional candle without the dangers associated with an open flame. I figured the hardest part of this project would be making the flicker look realistic, so I decided to let nature do that part for me.

Spencer // Senior » Josh Martin Photography Spencer // Senior My new friend Spencer and I hung out for a few hours last week. We talked about everything from church to sleeping patterns to living in a car to how to get a mortgage. Mando'a Ke jorhaa'ir Mando'a! Yes, it's true. There's a Mandalorian language, Mando'a. I developed it for Lucasfilm and now it's a functioning language that you can learn and speak. I'm not writing any more Star Wars, so I won't be developing the language further or adding to the dictionary as planned, and I'm not dealing with any more queries on it, but there's enough here to keep you busy for years. I'll leave it here as a fan resource indefinitely unless I'm asked to remove it by the copyright owner.

Sliced Glass ‘Paintings’ and Portraits by Loren Stump California-based glass artist Loren Stump specializes in a form of glasswork called murrine, where rods of glass are melted together and then sliced to reveal elaborate patterns and forms. While the murrina process appeared in the Mideast some 4,000 years ago, Stump has perfected his own technique over the past 35 years to the point where he can now layer entire portraits and paintings in glass before slicing them to see the final results. His most complex piece to date is a detailed interpretation of Leonardo da Vinci’s Virgin of the Rocks, which involved hundreds of glass components that were melted into a final piece. You can see more of Stump’s 2D and 3D work over on his website. (via Lost at E Minor)
