What's Inside the Deepest Hole in the World?

In 1970, Soviet scientists started drilling the Kola Superdeep Borehole in Murmansk, Russia. They wanted to learn about Earth's crust, and they wanted to beat American scientists who had abandoned their Project Mohole in 1966.

After 24 years of digging, and several branches in the hole, the deepest branch of the Kola Superdeep Borehole stopped in 1994 at 12,262 meters (about 7.5 miles). It's only nine inches in diameter at the bottom. It is still the deepest hole in the world, and the process of drilling was incredibly difficult. (For reference, the Mariana Trench is approximately 10,994 meters deep at The Challenger Deep—and it's not a drilled hole.)

Interestingly, Kola is not the longest hole; in May 2008, an oil well earned that record, though it's nowhere near as far underground.

So what did scientists find at the bottom of the hole? First, there's lots of water down there—though it may be formed from stray oxygen and hydrogen atoms squeezed out of rock minerals. Second, there are plankton fossils as deep as 6700 meters. Third, it's incredibly hot—more than 350 °F. For all the effort and decades of work, this hole only went 0.2% of the way to the center of the Earth!

For more on the findings, here's a SciShow video summarizing the project and its findings (plus the fact that it's "marked" today by a crumbling shack and a little well cap, shown above):

Little Baby's Ice Cream

Ice cream flavors can get pretty out-there, thanks to the growing number of creative scoop shops willing to take risks and broaden their customers’ horizons beyond chocolate, vanilla, and strawberry. Intrepid foodies can cool off with frozen treats that taste like horseradish, foie gras, and avocado, while Philadelphia's Little Baby’s Ice Cream is pushing the boundaries of taste with chilly offerings like everything bagel, Maryland BBQ, ranch, and cricket cake.

As Lonely Planet News reports, Little Baby’s Ice Cream launched its first signature “oddball” ice cream—Earl Grey sriracha—in 2011. Since then, its rotating menu has only gotten quirkier. In addition to the aforementioned flavors, customers who swing by Little Baby’s this summer can even try pizza ice cream.

The store created the savory flavor in 2011, to celebrate neighborhood eatery Pizza Brain’s inclusion into Guinness World Records for its vast collection of pizza memorabilia. The savory, Italian-esque snack is made from ingredients like tomato, basil, oregano, salt, and garlic—and yes, it actually tastes like pizza, Little Baby’s co-owner Pete Angevine told Lonely Planet News.

“Frequently, folks will see it on the menu and be incredulous, then be convinced to taste it, giggle, talk about how surprised they are that it really tastes just like pizza … and then order something else,” Angevine said. “That’s just fine. Just as often though, they’ll end up getting a pizza milkshake!”

Little Baby’s flagship location is in Philadelphia's East Kensington neighborhood, but customers can also sample their unconventional goods at additional outposts in West Philadelphia, Baltimore, and a pop-up stand in Washington, D.C.’s Union Market. Just make sure to bring along a sense of adventure, and to leave your preconceived notions of what ice cream should taste like at home.

Nalcrest, Florida: Where Postal Workers Go to Retire

You could say that the Nalcrest community in central Florida delivers affordable retirement housing for seniors. And with amenities like a pool and tennis courts, you might even say it has the whole package [PDF]. Or you could just go with the pun that the community itself has landed on: “Nalcrest: A First Class Community.”

Nalcrest, you see, is a retirement community exclusive to members of the National Association of Letter Carriers (NALC); the village has 500 ground-level apartments available for postal workers to enjoy after they’ve delivered their final Oriental Trading catalog. Garden-style units start at just $374 a month, including water, sewage, trash removal, basic cable, maintenance, and use of all of the recreational facilities.

The idea for an affordable, profession-specific retirement community came to NALC president William Doherty in the 1950s, when he toured Europe and saw similar setups organized by labor unions, religious groups, and fraternal organizations [PDF]. He proposed the idea for U.S. mail carriers as early as 1954, then pounced when Congress passed a law in 1959 that provided loans to build housing for seniors. Doherty was there to break ground on July 1, 1962; Nalcrest officially opened for business less than two years later on January 20, 1964. The dedication ceremony included a band of mail carrier musicians and a separate group called “The Singing Mailmen,” a group made up of—you guessed it—singing mailmen, as well as a female water skiing team that proudly flew pennants spelling out “Nalcrest.” After a stint as the ambassador to Jamaica, Doherty himself retired to Nalcrest, living there until his death in 1987.

Though residents may not be traipsing a daily mail route anymore, they still have plenty of options to stay active. Nalcrest has shuffleboard, horseshoes, bocce, miniature golf, tennis courts, an Olympic-size swimming pool, walking trails, and a softball diamond (home to the Nalcrest Eagles). It also boasts a travel club, a women’s association, and free art classes, among other activities. There’s one thing, however, it doesn’t have—dogs. With the exception of therapy dogs, Nalcrest has a no-canine rule in deference to retirees who were bitten in the line of duty and have an aversion to the animals.

If a dog-free community seems like paradise for postal workers, the other thing Nalcrest lacks cements its status as letter carrier nirvana: There are no mailboxes, because there is no home mail delivery. Each resident has to visit the Nalcrest post office to pick up any correspondence.
