Why You Should Never Flush Dental Floss Down the Toilet

Dental floss may be good for our teeth, but it’s bad for our sewer systems—which is why you should never flush the stringy product down the toilet.

Home toilets are designed with our convenience and hygiene in mind, but some people have taken to using them as de facto trash cans, flushing wet wipes, paper towels, feminine products, and other items. While gone from your bathroom in the blink of an eye, these waste products don’t just disappear into some magical abyss: They end up mucking up our pipes and pumps, causing problems at wastewater treatment plants and, in some extreme cases, merging with congealed oils, grease, fat, and waste to form noxious blobs called fatbergs.

Meanwhile, some wastewater treatment plant employees claim to have discovered everything from baseballs to cash to underwear—indicating that people are flushing far more than just household and sanitary products.

Compared to the objects above, dental floss—which is made from thin strands of nylon or Teflon—seems like it should be the least of any sewage worker’s concerns. And as you ready for bed, it’s probably far easier to toss your floss into the toilet than to remember to regularly empty the tiny trash can under your sink.

But since dental floss isn’t biodegradable, it doesn’t dissolve in its watery grave. Instead, it can combine with clumps of hair, toilet paper, wipes, sanitary products, and other gross stuff to form large clumps that clog sewers and pumps, sanitary companies told HuffPost. These blobs can also combine with tree roots and grease, cause sewage spills, and harm the motors in septic systems.

These instances aren't just inconvenient, they're also costly, as they result "in the need for local agencies that own and operate sewer systems to spend more money on maintenance to keep the sewers and pumps clear,” a spokesperson for the Sanitation Districts of Los Angeles County told HuffPost.

We’re not saying you shouldn’t floss regularly, but from here on out, the only things you should be flushing down the toilet are human waste and toilet paper.

For a clear idea of what other kinds of things shouldn’t be going down our drains, check out the video below, which was created by the City of Spokane Department of Wastewater Management and shared in partnership with the Water Environment Federation.

Want Priority Boarding On Your Alaska Airlines Flight This Holiday Season? Wear an Ugly Christmas Sweater

Between steep fares and crowded terminals, flying during the holidays isn’t fun. But on Friday, December 15, a special Alaska Airlines promotion will ease boarding stress and transform packed planes into mile-high ugly sweater parties, in honor of National Ugly Christmas Sweater Day. As the Los Angeles Times reports, the airline will offer free early boarding to travelers willing to don their holiday worst at the airport.

The promotion is good for all Alaska Airlines flights in the airline’s 115-city network, and for flights offered by Virgin America and Horizon Air (both of which are operated by Alaska Airlines). In addition to escaping the waiting crowds, passengers who share the most festive knitted looks will be featured on Alaska Air's social media pages if they tag their photos and videos using the hashtags #UglySweaterDay and #MostWestCoast. And since no plane aisle-turned-catwalk is complete without a soundtrack, “festive holiday-themed boarding music will play all month long to help get guests into the holiday spirit,” according to a press release.

Worried you’ll be the only person on the plane wearing a sequined Rudolph cardigan? Even if other passengers don’t get the memo, airline crew will also be wearing ugly sweaters—so feel free to unleash your inner Chevy Chase from National Lampoon's Christmas Vacation.

Why You Should Think Twice About Drinking From Ceramics You Made by Hand

Ceramic ware is much safer than it used to be (Fiesta ware hasn’t coated its plates in uranium since 1973), but according to NPR, not all new ceramics are free of dangerous chemicals. If you own a mug, bowl, plate, or other ceramic kitchen item baked in an older kiln, it may contain trace amounts of harmful lead.

Earthenware is often coated with a shiny, ceramic glaze. Historically, lead has been used in glazes to give pottery a glossy finish and brighten colors like orange, yellow, and red. The chemical is avoided by potters today, but it can still show up in handmade dishware baked in older kilns that contain lead residue. Antique products from the era when lead was a common crafting material may also be unsafe to eat or drink from. This is especially true when consuming something acidic, like coffee, which can cause any lead hiding in the glaze to leach out.

Sometimes the amount of lead in a product is minuscule, but even trace amounts can contaminate whatever you're eating or drinking. Over time, exposure to lead in small doses can lead to heightened blood pressure, lowered kidney function, and reproductive issues. Lead can cause even more serious problems in kids, including slowed physical and mental development.

As the dangers of even small amounts of lead have become more widely known, the ceramics industry has gradually eliminated the additive from its products. Most of the big-name commercial ceramic brands, like Crock-Pot and Fiesta ware, have cut it out all together. Independent artisans have also moved away from working with the ingredient, but there are still some manufacturers, especially abroad, that use it. Luckily, the FDA keeps a list of the ceramic ware it tests that has been shown to contain lead.

If you’re not ready to retire your hand-crafted ceramic plates, the FDA offers one possible solution: Purchase a home lead testing kit and analyze the items yourself. If the tests come back negative, your homemade dishware can keep its spot on your dinner table.

This piece was updated to clarify that while lead may be present in antique ceramics and old kilns, it's no longer a common ingredient in ceramic glazes.
