Why Do Coins Make Your Hands Smell Funny?

A lot of people assume that it's just the way that coins smell, and the odor is rubbing off on their hands, but you're not smelling the metal so much as you're smelling yourself. That funky scent is actually a human body odor created by the reaction of oils in the skin contact with objects that contain iron (a separate, but similar odor, is created when we touch copper). What we think of as a "metallic smell" is only metallic by association.

Here's how it works.

When you touch something made of iron, perspiration on your skin cause the iron atoms to gain two electrons, and these doubly negative iron atoms react with oils in the skin, forming several types of compounds called aldehydes and ketones. If you've gotten a whiff of formaldehyde while dissecting frogs in science class or wrinkled your nose at the smell of acetone in nail polish remover, then you know that these compounds have very strong, distinctive odors.

When German researchers captured and studied the chemical composition of vapors coming from the skin of people who had just handled iron objects, they found one compound, 1-octen-3-one, that has a particularly pungent fungus-meets-metal smell and is detectable by humans at very low concentrations. This compound may be the main component of the odor of your hands post-money-handling.

You might have noticed that a similar smell is produced when blood meets skin. That's because blood contains iron and these iron atoms go through the same reaction you're your skin as the atoms from coins, producing the same scent molecules.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

Five rooms of one's own.

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

Who Was Jim Crow?

The name Jim Crow appears throughout many U.S. history books. It's used in reference to both the laws that segregated Black and white Americans in the Southern United States and the region itself during the period when these laws were enforced. Jim Crow Laws and the Jim Crow South were very real from the late 19th through the mid-20th centuries, but a real person named Jim Crow never existed. The name comes from a fictional character used to perpetuate racist stereotypes before the Civil War.

According to Ferris State University, a white performer named Thomas Dartmouth Rice originated the Jim Crow caricature in the 1830s. Rice, known as "the Father of Minstrelsy," would don blackface and affect an exaggerated African American dialect while performing his musical act. Jim Crow was meant to be a racist stereotype of an enslaved person: Like many minstrel personas that came after him, the character was portrayed as a clumsy buffoon.

Though Rice didn't invent minstrelsy, his success helped popularize the stage show format. Inspired by Rice, other minstrel actors borrowed his Jim Crow routine, and soon whites were using the name as a derogatory term for African Americans.

Even after slavery was abolished and minstrel shows faded into obscurity, the Jim Crow character lived on as a label. According to History, the first Jim Crow laws were passed in the Reconstruction Period as a way to limit the rights and resources of newly freed Blacks in the South. Such laws imposed literacy tests on Black voters, segregated public schools, and made it legal for businesses to segregate their customers by race.

How exactly these laws became associated with Jim Crow is unclear, but the phrase Jim Crow Laws was being used by the late 19th century. An 1892 article from The New York Times used the wording when reporting on Louisiana's segregated railroad cars.

Though most people may not be aware of the name's origins, Jim Crow still comes up today when discussing this dark period in U.S. history and its lasting effect on the country.
