'Whistling' Bullets Uncovered From Ancient Roman Battlefield

 

When archaeologists recently uncovered bullets from a Roman battle site in Scotland, they noticed something unusual about them: They had been pierced with 5-millimeter holes. As Live Science reports, the archaeologists believe the feature was meant to create an intimidating whistling effect as the projectile plummeted towards Roman enemies.

The Burnswark Hill dig, being led by John Reid of the Trimontium Trust, is the first major archaeological project at the site in 50 years. Roman troops staged an attack on indigenous defenders in a hilltop fort there about 1800 years ago. The whistling cast lead bullets, which soldiers would have hurled at their foes with a sling, accounted for about 20 percent of the bullets uncovered there so far.

The fact that Romans had taken the time to drill holes in the weapons initially had the experts confused. Such a procedure would have taken a considerable amount of effort only to end up with projectiles that are less heavy and therefore, less damaging. Reid never considered that the holes were meant to make noise until his brother—inspired by his fishing lures, which have a hole in the side and make a whistling noise when he casts a line—suggested the possibility.

After testing replicas of the bullets, the theory was found to hold some water. The holes did indeed make mechanical whistle noises that Reid, writing in the magazine Current Archaeologydescribed as "eerily reminiscent of an agitated wasp."

Whether or not the sound was used for intimidation is still up for debate, but the Romans wouldn't have been alone in using similar objects to antagonize their targets. In ancient China, Shàojiàn or "shrieking arrows" were used to startle animals between release and impact. And this video shows an example of the "death whistles" that may have been played by Aztec soldiers when marching into battle to psych out the enemy. (Take a listen: The unsettling sound lives up to the instrument's morbid name.) The Burnswark Hill bullets mark the first of their kind ever uncovered from an ancient Roman site.

25 Things You Didn’t Know You Could Recycle

According to the EPA, Americans generate 254 million tons of waste each year. Here are a few things you may have been throwing out that, with a little effort, you can actually recycle.

1. DENTURES

Grandpa's choppers may hold $25 worth of recyclable metals, including gold, silver, and palladium. The Japan Denture Recycling Association is known to collect false teeth, remove and recycle the metals, and discard the rest of the denture (which is illegal to reuse). The program has donated all of its earnings to UNICEF.

2. HOLIDAY LIGHTS

Got burnt out holiday lights? The folks at HolidayLEDs.com will gladly take your old lights, shred them, and sort the remaining PVC, glass, and copper. Those raw materials are taken to another recycling center to be resurrected. (In 2011, the State of Minnesota collected and recycled around 100 tons of dead lights.)

3. SEX TOYS

The first step in recycling your toy is to send it to a specialty processing plant, where it's sterilized and sorted. There, all "mechanical devices" are salvaged, refurbished, and resold. Silicone and rubber toys, on the other hand, are "ground up, mixed with a binding agent, and remolded into new toys," according to the aptly titled website, Sex Toy Recycling. Metals, plastics, and other leftovers retire from the pleasure industry and are recycled into conventional products.

4. HOTEL SOAP

Not all hotels throw out that half-used soap you left in the shower: Some send it to Clean the World. There, soap is soaked in a sanitizing solution, treated to a steam bath, and then tested for infections. Once deemed safe, the soap is distributed to less fortunate people across the globe. So stop stealing soap from hotels—you may be stealing from charity.

5. MATTRESSES

You don't need to dump your old box spring at the landfill. Equipped with special saws, mattress recycling factories can separate the wood, metal, foam, and cloth. The metal springs are magnetically removed, the wood is chipped, and the cloth and foam are shredded and baled. In its future life, your saggy mattress can become a summer dress or even wallpaper.

6. COOKING OIL

When you’re finished making French fries at home, it can be tempting to toss the spent frying oil down the drain. But you shouldn’t—approximately 47 percent of all sewer overflows are caused by fat and oil. There are a few curbside programs in the United States that accept used cooking oil, which may send the oil to a biodiesel plant that will transform it into fuel. To see if there’s a collection point near you, check this website.

7. DIRTY DIAPERS

The average baby soils 6000 diapers before being potty trained—that's one ton of diapers rotting in a landfill per child. But not all poo-packages have to suffer this fate. The company Knowaste collects and recycles dirty diapers at hospitals, nursing facilities, and public restrooms. After sanitizing the diaper with a solution, they mechanically separate the "organic matter" from the diaper's plastic, which is compressed into pellets and recycled into roof shingles. Meanwhile, paper pulp in diapers grows up to become wallpaper and shoe soles.

8. CDS

CDs are made of polycarbonate and won't decompose at a landfill. But if you send your discs to The CD Recycling Center, they'll shred them into a fine powder that will be later melted down into a plastic perfect for automotive and building materials—even pavement!

9. SHOES

Send your beat-up sneaks to Nike Grind and you'll help build a running track. Nike's recycling facility rips apart worn shoes, separating the rubber, foam, and fabric. The rubber is melted down for running track surfaces, the foam is converted into tennis court cushioning, and the fabric is used to pad basketball court floorboards. So far, Nike has shredded more than 28 million pairs of shoes.

10. SHEEP POOP

Why turn sheep poop into fertilizer or manure when you can make it into an air freshener? The folks at Creative Paper Wales do that, plus more—they can transform sheep poop into birthday cards, wedding invitations, bookmarks, and A4 paper! Sheep dung brims with processed cellulose fiber. The poo can be sterilized in a 420 degree pressure cooker, which separates the fiber from a smelly brew of liquid fertilizer, allowing the fiber pulp to be collected and blended with other recycled pulps, creating tree-free paper.

11. TROPHIES

Is your room full of plastic bowling trophies from fifth grade? If the thrill of victory fades, you can recycle your old trophies at recycling centers like Lamb Awards. They'll break down your retired awards, melting them down or reusing them for new trophies.

12. HUMAN FAT (WARNING: ILLEGAL)

If it weren't for legal complications, America's obsession with cosmetic surgery could solve its energy problem. In 2008, a Beverly Hills plastic surgeon lost his job when police caught him fueling his car with a biofuel created from his patients' liposuctioned fat. (Convicting him wasn't hard, since he advertised the substance online as "lipodiesel.") That's not the first time fat has powered transportation: In 2007, conservationist Peter Bethune used 2.5 gallons of human fat to fuel his eco-boat, Earthrace.

13. ALUMINUM FOIL

Foil is probably one of the most thrown away recyclable materials out there. (Americans throw away about 1.5 million tons of aluminum products every year, according to the EPA.) But foil is 100 percent aluminum, and as long as you thoroughly clean it of any food waste, you technically should be able to recycle it with your aluminum cans (but first check with your local recycling plant to ensure they’re equipped to process it; some aren’t).

14. CRAYONS

iStock

Don't toss those stubby Crayolas! Instead, mail them to the National Crayon Recycle Program, which takes unloved, broken crayons to a better place: They're melted in a vat of wax, remade, and resold. So far, the program has saved more than 118,000 pounds of crayons.

15. DEAD PETS

When Fluffy bites the dust in Germany, you can memorialize your beloved pet by recycling her. In Germany, it's illegal to bury pets in public places. This leaves some pet owners in a bind when their furry friends die. A rendering plant near the town of Neustadt an der Weinstraße accepts deceased pets; animal fat is recycled into glycerin, which is used in cosmetics such as lip balm.

16. SHINGLES

iStock

The EPA estimates that 11 million tons of shingles are disposed each year [PDF]. Most of them are made out of asphalt, which is why more than two dozen states pulverize the old shingles and recycle them into pavement. For every ton of shingles recycled, we save one barrel of oil.

17. PRESCRIPTION DRUGS

iStock

You can—and should—properly dispose of expired prescription drugs. But what about unneeded pills that are still good? Some states let you donate unused drugs back to pharmacies. Some charities also accept leftover HIV medicine from Americans who have switched prescriptions, stopped medicating, or passed away. These drugs are shipped overseas and distributed to HIV victims around the world.

18. FISHING LINE

Fishing line is made from monofilament, a non-biodegradable plastic that you can't put in your everyday recycling bin. At Berkley Fishing, old fishing line is mixed with other recyclables (like milk cartons and plastic bottles) and transformed into fish-friendly habitats. So far, Berkley has saved and recycled more than 9 million miles of fishing line.

19. WINE CORKS

iStock

Your recycling center probably doesn't accept wine corks, but companies like Terracycle and Yemm & Hart will. They turn cork into flat sheets of tile, which you can use for flooring, walls, and veneer. Another company, ReCORK, has extended the life of over 4 million unloved corks by giving them to SOLE, a Canadian sandal maker.

20. PANTYHOSE

iStock

Most pantyhose are made of nylon, a recyclable thermoplastic that takes more than 40 years to decompose. Companies like No Nonsense save your old stockings by grinding them down and transforming them into park benches, playground equipment, carpets, and even toys.

21. TOOTHBRUSHES

iStock

If you buy a plastic toothbrush from Preserve (which makes its toothbrushes from old Stonyfield Farms yogurt cups and other everyday items), it will take back your used toothbrush and give it a new life—this time as a piece of plastic lumber!

22. TENNIS BALLS

iStock

The company reBounces doesn’t really recycle tennis balls, it resurrects them. If you’ve got at least 200 balls sitting around, the company will send you a prepaid shipping label to help get the box on the road and repressurize the balls.

23. YOGA MATS

iStock

Most yoga mats are made from PVC, the same material in plumbing pipes, heavy-duty tarps, and rain boots. While many local yoga studios will accept well-loved mats and find them a new home, the company Sanuk has an appropriately squishy vision for each mat’s future: It will transform your old yoga mat into flip flops.

24. DEFUNCT CURRENCY

iStock

All governments have a way of dealing with old, worn money. (In 2016, the Indian government shredded old bills and turned them into hardboard.) But what about currency that is no longer legal tender? Ends up you can donate your old French francs, Spanish pesetas, or Dutch guilders to Parkinsons UK, who will recycle the old coins and banknotes.

25. PET FUR

iStock

All of the pet fur on your sweaters, your couches, and your carpet could help save the ocean from oil spills. Hair is excellent at sopping up oil from the environment (hairball booms were used to soak up oil from the 2010 BP Oil Spill), so non-profit organizations such as the San Francisco-based Matter of Trust will accept pet fur to make oil-absorbing mats of Fido's fuzz.

UK Man Orders Kindle, Receives Tumor Specimen Instead

Global shipping services, like FedEx, deliver millions of packages each day, so it’s understandable that some things can get mixed up in the process. James Potten of Bristol, England recently received what he thought was a Kindle e-reader. Instead, a “specimen return kit” with a tumor inside was delivered to his door.

Described by the BBC as a “courier mix-up,” the FedEx sleeve that the tumor was delivered in was addressed to Mr. Potten but it was intended for the Royal Free Hospital in London, approximately 2.5 hours away.

“My name was on the outside, but the contents weren't what I expected,” Potten told BBC. “I haven't opened the sealed box, which says exempt patient tissue, as it doesn't belong to me. The tracking code on the item had the same first five and last three numbers as my order but it wasn't my Kindle.”

The confused addressee took to Twitter to share his “#FedExFail” with the rest of the world:

Potten later tweeted that the tumor was recollected by FedEx for delivery to the hospital, and he did eventually receive his Kindle. The delivery company said that it will “consider future changes to our processes” so that instances like this won’t happen again.
