There's a Reason Why It Smells Extra Gross If You Fart in the Shower

No, it’s not just you: Farts really do smell worse when you let one rip while taking a steamy shower. But it’s not like water contains magical properties that make flatulence more potent, right? So what gives?

As Hank Green explains in SciShow’s latest video, part of the reason for the extra-noxious fumes is simply that you’re stuck in an enclosed space, so your butt blasts have nowhere to migrate. Plus, you’re not wearing clothing to absorb or lock the smell in.

That said, the bathroom’s humidity probably also plays a part, as research shows that water vapor in the air can actually enhance your sense of smell. Scientists don’t know why exactly this is, but one possibility is that “the water vapor helps the molecules that make up the smell interact with receptors in your nose,” Green explains. Another theory is that the gas particles bind to the water vapor, as if the air were a sponge for your fart molecules. This allows it to hold more of the stench than plain old dry air.

Either way, the result is a shower experience that doesn't exactly make you feel squeaky clean. Learn more smelly facts about shower farts by watching the video below.

7 Human Body Parts That Were Once Used as Medicine

For hundreds of years, from at least the Renaissance through the Victorian era, medicine in England, Italy, France, and other European countries routinely involved the use of the dead human body. Bones, brains, blood, and more were believed to be able to cure everything from gout to epilepsy, thanks to the life-giving spirit imparted by the deceased. Although today the use of corpses is still an integral part of our healthcare—from tissue transplants to blood transfusions—the bulk of the practice of "medical cannibalism" has, thankfully, died out.

1. ANY PART OF A MUMMY

Arguably the most popular and the most difficult to find of the bunch, mummy was considered practically a panacea during the golden age of corpse medicine in the 16th and 17th centuries. Brought back from plundered Egyptian tombs, it was added to tinctures or plasters used to combat bleeding, venomous bites, bruising, and joint pain. Unfortunately, demand far outweighed the ill-gotten supply, and clever entrepreneurs cashed in on the craze by preparing fake mummies from the bodies of lepers, beggars, and even camels.

2. SKULLS

If powdered corpse was powerful, powdered corpse with chocolate was doubly so—at least according to Thomas Willis, a 17th-century scientist who combined skulls and cocoa in a cure for bleeding. Human skulls were also soaked in alcohol, creating a tincture called “the King’s drops,” since King Charles II of England allegedly paid £6000 for a personal recipe. The tincture was said to be good for gout, dropsy (edema), and "all fevers putrid or pestilential," among other ailments.

Nosebleeds and epilepsy were also treated with a powder made from moss growing on human skulls. Richard Sugg, the author of Mummies, Cannibals and Vampires: The History of Corpse Medicine from the Renaissance to the Victorians, says that this cure actually did work—but only because powder stimulated coagulation.

3. BRAINS

Brains were also used to cure epilepsy. Physician John French describes the process for making a tincture of brains in his 1651 book The Art of Distillation: “[T]ake the brains of a young man that hath died a violent death,” mash in a stone mortar, steep in wine, and “digest it half a year in horse dung” before distilling.

This remedy was supposed to work under the "like cures like" theory of medicine popular at the time, in which skulls and brains were seen as especially useful for curing illnesses thought to stem from the head. Cures taken from corpses that had died horribly were often thought to be extra powerful, because violence was seen to somehow concentrate the life force.

4. FAT

Human fat was a sought-after remedy for bleeding, bruising, muscle cramps, nerve damage, joint pain, and a variety of other afflictions. It was especially popular in Germany, and was delivered to Munich’s doctors by enterprising executioners until the mid-18th century. Others sought to bypass the apothecary entirely and went straight to the executioner for their medicinal supplies. Often the fat was made into a salve (sometimes known as "hangman's salve"), but one physician to several English and French kings combined the ingredient with hemlock and opium and administered it as a pain-reducing plaster.

5. BLOOD

Like fat and brains, blood was also often procured directly from the executioner. People who were too poor to afford the fine wares of their local apothecary went instead to the gallows, where they paid a few coins to drink the fresh blood of the recently executed. Though usually drunk straight, blood was also dried and powdered (to cure nosebleeds), sprinkled on wounds (to stop bleeding), or even made into a kind of human marmalade.

6. HAIR

According to Sugg, a tonic called “liquor of hair” was regularly used to encourage hair growth in those who were balding. Under the like cures like theory, the hair of a deceased person was believed to help with the hair of the living. However, powdered hair was also administered for complaints that had nothing to do with heads—including jaundice.

7. TEETH

Teeth, too, were an example of "like cures like." In North Hampshire, England, and other areas, people wore teeth taken from corpses in a bag around their neck as a remedy for toothache, an ailment that could also be treated by touching a cadaver’s tooth to your own. In Ireland, people went even further, and believed that toothache could be cured by rubbing the afflicted gum with the finger of a corpse, or even washing it with some water that had also been used to wash the dead body.

Paris Responds to Its Public Urination Problem By Installing Open-Air Urinals

In between stops at the Louvre and the Eiffel Tower, sightseers in Paris might notice some unusual new landmarks marking the city's streets: bright red, open-air urinals. As NPR reports, the so-called "Uritrottoir" (a mashup of the French words for urinal and pavement) have been installed in response to the city's public urination problem, and residents aren't happy about it.

Peeing openly on the streets has been an unofficial tradition in the French capital since the pre-Napoleon era. Relieving oneself on city property is a fineable offense, but that hasn't stopped both tourists and locals from continuing to do it, subjecting bystanders to both the unwelcome sight and the lingering smell.

Now, Paris is taking an if-you-can't-beat-'em-join-'em approach to the issue. Uritrottoir have popped up near some of the city's most famous spots, such as Île Saint-Louis, overlooking the Seine, and Notre-Dame Cathedral. They're about the height and size of trash cans, with a receptacle that's meant to catch pee, not litter. Inside the Uritrottoir, straw and other composting materials absorb the urine and its odors, eventually breaking down into a compost that will feed the plants growing from the top of the box. A conspicuous sign of a man peeing posted above the urinal lets passersby know exactly what the contraption is for.

The built-in planters are meant to present the public urinals as something beautiful and functional, but many of the people who have to look at them every day aren't buying it. Fabienne Bonnat, a local art gallery owner, told CBC Radio, "It's an open door to exhibitionism. Who likes to see that?"

Another Île Saint-Louis gallery owner, who didn't wish to be named, told Reuters, “We’re told we have to accept this but this is absolutely unacceptable. It’s destroying the legacy of the island. Can’t people behave?"

The first three toilets were installed in March with a fourth appearing in July. The city has plans to add a fifth urinal, despite the uproar they've already caused.
