    Am Shooting Journal ^ | 7/21/2017 | J Hines
    YouTube channel TAOFLEDERMAUS encourages its viewers to send in handmade ammunition to practice shooting with. In one of their videos, one viewer called Sam came up with the idea to create glass shotgun slugs and sent them in. Basically they wanted to see whether the glass slugs would survive the intense shock of being shot out of a gun and hit what they’re aiming at. You might think that firing something made of glass wouldn’t work very well. The creator of these glass slugs did a great job and to add to its destructive capabilities, there’s a nail hidden inside...

    Prince Rupert’s drop. ============================================================================================================================ (Phys.org)—Researchers have finally answered a question that has stumped scientists since the early 1600s: Why are the heads of tadpole-shaped pieces of glass called "Prince Rupert's drops" so strong? In the 17th century, Prince Rupert from Germany brought some of these glass drops to England's King Charles II, who was intrigued by their unusual properties. While the head of the drop is so strong that it can withstand the impact of a hammer, the tail is so fragile that bending it with your fingers will not only break the tail, but cause the entire droplet to...

    HONG KONG - China's largest auto glass manufacturer, Fuyao Glass Industry Group <600660.SS>, will press ahead with investments worth about $1 billion in the United States this year despite criticism at home amid growing China-U.S. tensions, the company's chairman said. The company also expects to invest a further $130 million in Germany and Russia this year as it looks to tap into more high-end overseas markets, Cao Dewang told Reuters in an interview in Hong Kong on Monday. Cao, whose company is already the biggest investor in Ohio, said he planned to create about 4,500 jobs by setting-up plants in...

    Construction of the tallest building west of the Mississippi is scheduled to be completed in downtown Los Angeles in four months, but a neighbor of the new Wilshire Grand Hotel is calling for a halt to the project because of glare from the tower’s glass exterior. EYP Realty, a real estate management firm next to the $1-billion project, has filed a protest with the city of Los Angeles, asking that the project’s building permit be revoked and that the glass exterior of the 1,100-foot structure be replaced. “The installation of the very reflective glass is a clear violation of the...
  • Apple's use of 'sapphire' in iPhone camera lens questioned in new tests

    Apple has been using sapphire on its iPhone camera lenses for a few years now since the launch of the iPhone 5S, but it might not be as scratch resistant as you'd expect. A new video raises questions over Apple's use of sapphire in its iPhone camera lens, and includes scratch tests to rate its durability. While Apple claims it uses sapphire crystal in its iPhone lens, tests by YouTuber JerryRigEverything show that Apple could be using a more cost effective sapphire laminate on top of regular glass. JerryRigEverything tested Apple's iPhone lens with an XRF machine and electron microscope,...

    hould children be allowed in art galleries? In 2014 Jake Chapman caused a minor furore, and prompted a lot of column inches, when he said that taking kids to galleries was a “waste of time”. He told The Independent parents were "arrogant" for thinking their children could understand artists like Jackson Pollock or Mark Rothko, adding "children are not human yet". The two children in this video, which has been going viral in recent days, clearly couldn’t give a hoot what Jake Chapman has to say about their appreciation of art. ...

    5:30 A.M., Monday July 16th, 1945: The day dawned brighter than ever before over the New Mexico desert. But it was not the Sun's soothing rays that set the landscape alight; it was the radiant flash of the very first atomic bomb. Trinity, the nuclear offspring of the Manhattan Project, detonated with the force of 21,000 tons of TNT. The accompanying fireball reached temperatures of 8,430 degrees Kelvin, hotter than the surface of the sun, and sent a mushroom cloud of smoke and debris soaring more than seven miles into the sky. That day, every human on the planet was...

    An archaeological excavation in northern Israel has unearthed glass-making kilns that date back 1,600 years, proving that ancient Israel was one of the most important centers of glass making in the world during the late Roman period. Yael Gorin-Rosen, head curator of the Israel Antiquities Authority’s Glass Department, said. “This is a very important discovery with implications regarding the history of the glass industry both in Israel and in the entire ancient world. We know from historical sources dating to the Roman period that the Valley of Acre was renowned for the excellent quality sand located there, which was highly...

    In 1996 in the Egyptian Museum in Cairo, Italian mineralogist Vincenzo de Michele spotted an unusual yellow-green gem in the middle of one of Tutankhamun's necklaces. The jewel was tested and found to be glass, but intriguingly it is older than the earliest Egyptian civilisation. Working with Egyptian geologist Aly Barakat, they traced its origins to unexplained chunks of glass found scattered in the sand in a remote region of the Sahara Desert. But the glass is itself a scientific enigma. How did it get to be there and who or what made it? Thursday's BBC Horizon programme reports an...

    A congressman stole the water glass Pope Francis was drinking out of during his address at the White House on Thursday. Representative Bob Brady, a devout Catholic and Democrat from Pennsylvania immediately made his way to the podium after Pope Francis finished speaking and grabbed the glass that was still filled with water. He then drank the water, gave some of the water to his wife Debra, and saved the rest for his grandchildren. Representative Brady took photos as well, and had his staff send them out to the press.

    There is a beach in Fort Bragg, California, that’s famous for the iridescent sea glass that shimmers on its shores. A dump until the 1960s, Glass Beach underwent massive cleanup projects in the late 1990s and early 2000s, but the glass from bottles and other items remained, worn smooth over time as it tumbled through the ocean... In fact, even though removing sea glass from the beach is prohibited, rangers from California State Parks, which owns the beach, see people taking the smooth, pebble-like glass pieces home in Ziploc bags and buckets all the time

    Imagine a glass window that's tough like armor, a camera lens that doesn't get scratched in a sand storm, or a smart phone that doesn't break when dropped. Except it's not glass, it's a special ceramic called spinel {spin-ELL} that the U.S. Naval Research Laboratory (NRL) has been researching over the last 10 years. "Spinel is actually a mineral, it's magnesium aluminate," says Dr. Jas Sanghera, who leads the research. "The advantage is it's so much tougher, stronger, harder than glass. It provides better protection in more hostile environments—so it can withstand sand and rain erosion." As a more durable...

    For Democrats, 2016 is the year they hope to shatter the nation's highest and toughest glass ceiling. But so far, the party's self-declared glass ceiling cracker has the party's other women waiting on her. While Hillary Clinton makes up her mind about whether to make another White House bid, other Democratic women with presidential ambitions aggressively insist they're not running this time around. They've signed a letter encouraging Clinton to jump in. They've gone to early nominating states to tout her candidacy — while sometimes turning down their own invitations to those same states for fear of sending signals that...
