Man attempts to sharpen a dollar-store kitchen knife

knife

Using Japanese sharpening stones of various grits and considerable prices, Junskitchen set out to try and make an edge of a $1 kitchen knife. The results are impressive—but how long will they last?

[1,000 and 6,000] grits would be enough for a normal household knife. I used grits 1,000, 2,000, 5,000, 8,000, and 12,000 in this video. The higher the number, the finer the sanding and the sharper the knife will be.

Watch formerly homeless people make jackets that double as sleeping bags

empwr-coat-01

The Empowerment Plan is a Detroit-based organization that creates manufacturing jobs making EMPWR coats that double as sleeping bags:

Via designboom:

the empowerment plan is a detroit-based, nonprofit organization focused on permanently elevating families from the generational cycle of homelessness. it hires single parents from local shelters and provide them with training and full-time employment as seamstresses so that they can earn a stable income, find secure housing, and regain their independence. the individuals it hires manufacture a coat designed to meet the needs of those in the homeless community. the durable ‘EMPWR coat’ can transform into a sleeping bag at night or an over-the-shoulder bag when not in use. since 2012, it has provided employment to 34 homeless individuals—all of whom have now secured permanent housing for themselves and their families—and distributed over 15,000 coats to those in need across the US and canada.

Neat demonstration of EDM cutting technology

snowflake

EDM (electrical discharge machining) cuts through thick plates of steel within +/- 0.0001".

From Core 77:

In the variant of this production method known as wire EDM, the cutting is done with a thin brass wire and the fun combination of electricity and water. Wire EDM is what you use when you want to cut something that's, say, 300mm thick, and made out of a tough-to-machine metal.

See firsthand what it's like to rip down one of the heaviest downhill mountain bike tracks ever created, through the GoPro view of the creator himself, Dan Atherton. It's why Red Bull Hardline is an event like no other. The long and technical course plays on a variety of disciplines, where incredibly steep and rocky technical sections were combined with a motocross run in and 50-foot gap jump to create one of the most progressive downhill courses on the planet.

Hippo attacks car

Screen Shot 2016-11-29 at 10.30.25 AM

Wikus Ceronie, a welding inspector, describes his encounter with a truculent hippo:

This is my first time ever working in Mozambique and I was on a jolly journey back home to South Africa.

I was crossing the border from Kruger National Park when I noticed a hippo on the bridge. There were people walking around in the nearby vicinity so I automatically assumed this hippo was used to humans. I was quite fascinated by this so I took out my phone to start filming.

Suddenly the hippo turned and just started charging… I braced myself as I realized he wasn’t going to stop. He hit the bakkie head on and then tried biting it. I guess after that he decided he had won because he just turned around and left.

This was terrifying for me because I realized I had nowhere to go and no time to do it in. Beside me was a 50m drop so had he hit me on the side I have no doubt the car would have rolled down the embankment. Even though there was damage done to the bonnet of my vehicle and the door couldn’t open, I’m grateful there were no serious injuries at the end of day.

Gentleman who smuggled $165,000 worth of gold in his rectum promises to pay it back

Screen Shot 2016-11-29 at 10.22.43 AM

While employed at the Royal Canadian Mint, Leston Lawrence secreted 22 gold "pucks" into his rectum. He removed them and sold them for $165,000. He will be sentenced by Ontario Court Justice Peter Doody (yes, Doody).

From CBC:

Lawrence worked at the mint from July 2008 until March 2015. His job included purifying gold — jewelry, coins and bars purchased by the mint — by melting it, injecting it with chlorine gas and skimming off base metal until the molten gold was 99.5 per cent pure.

Once he believed the molten gold was pure, he was to scoop some out with a ladle, let it cool and then test it for purity. He was supposed to return the pucks into the vat of molten gold after testing.

Lawrence "clearly had the opportunity" to steal the gold because he often worked alone, and the security cameras would not have caught him slipping gold pucks into his pocket, Doody ruled. "His locker contained Vaseline and latex gloves, which could have been used to insert a puck into his rectum," he ruled, adding that there were no cameras in the locker room.

Englands new £5 notes contain animal fat, angering vegans

Screen-Shot-2016-11-29-at-9.52.31-AM

The Bank of England confirmed that its new £5 notes contain animal fat. “There is a trace of tallow in the polymer pellets used in the base substrate of the polymer £5 notes,” it tweeted yesterday. There's a petition underway to replace them with vegan currency.

The new £5 notes contain animal fat in the form of tallow. This is unacceptable to millions of vegans, vegetarians, Hindus, Sikhs, Jains and others in the U.K.

We demand that you cease to use animal products in the production of currency that we have to use.

The petition has 26,260 supporters so far.

Hyperinflation in Venezuela - merchants are weighing, not counting, currency

3lE9yR

Venezuela's currency is on track to inflate by 720 percent this year. Why? The drop in the price of oil hurt Venezuela's economy, and President Nicolás Maduro thought he could solve the problem by printing more money. It didn't work and now people are starving.

From The Independent:

When the price of oil on the global market collapsed by two-thirds in 2014, Venezuela had little else to fall back on, so a natural reaction would have been for the bolívar to collapse. But Mr Maduro, who succeeded Hugo Chávez following the revolutionary leader's death in 2013, instead tried to control the exchange rate, creating a massive black market for currency.

Figuring out scams to get dollars and then sell them for bolívars became hugely lucrative business for Venezuelans, setting off a feedback loop that drove the inflation rate higher and higher.

In one of Caracas richer neighbourhoods, the owner of a tiny kiosk selling newspapers, cigarettes and snacks told the Washington Post that every evening he quietly stuffs a plastic bag full of the day’s earnings, around 100,000 bolívars (about £42) in notes of 10, 20, 50 and 100 bolívars. Venezuela has one of the highest crime rates in the world, and he said carrying that much cash frightens him.
