Ever wonder how they work? No electricity, motors, or anything like that? Flush toilets are taken for granted by half of the world’s population, except when there’s a malfunction.

For perspective, check this roll. Well, actually two rolls today – it’s a Double Tendrils occasion.

1. You visit a toilet about 2,500 times a year. And that’s under normal conditions.
2. The bathroom is a leading cause of arguments among couples. As for other family members or housemates?
3. In a public restroom, the first toilet cubicle in a row is the least used and thus the cleanest of all. Not the last one?
4. The more features your smart phone has, the longer you sit on the can.
5. More than 7 million people in the U.S. admit to dropping their cell phones in the bowl.
6. The average kitchen chopping board has twice as the fecal bacteria than a toilet seat. And mobile phones have 18 times more bacteria than do toilet handles.
7. When it comes to replacing the toilet paper, three out of four people put the flap in front, away from the wall.
8. For the latest in modern comforts, high-tech toilets can lift their lids when they sense you approaching or instantly warm the seat to your body temperature. Some will wash your rear and blow warm air to dry it, a feature of note for mobility-limited people.
9. Some high-tech toilets even clean themselves. I assume that would ease some of those arguments back in item 2.
10. Much of the other half of the world population relies on dry privies such as outhouses, pit latrines, port-a-potties, composting or incinerating toilets, and “treebogs” surrounded by nutrient-absorbing plants.

Now, for some historical and global angles.

1. The ancestor of the modern porcelain john was created by Sir John Harington, a godson of Queen Elizabeth I. Banished from the court on account of his bawdy verses and humor (how appropriate), he wound up in Bath in southwest England and devised a flushing toilet in 1596. Its system of handles emptied water from a tank at the same time the user opened levers to flush the toilet contents down the drain to who knows where. Allegedly, the contraption brought him back into the queen’s good graces.
2. The modern household throne typically relies on two developments. The first is the ballcock, the bobbing mechanism inside a toilet tank, which prevents water from overflowing in a storage tank. Invented by Mexican priest and scientist Jose Antonio de Alzate y Ramirez around 1790 and early applied to steam engines, it eventually provided toilets with the flush of water that generates a siphon that sucks the toilet bowl contents up and over a trap and then away. Thus, the second breakthrough development, the S trap by Scottish mechanic Alexander Cumming in 1775, collects water in the bowl and prevents sewer gases from escaping into the bathroom. Further advances soon followed, largely in England.
3. Contrary to legend, plumber and businessman Thomas Crapper did not invent the flush toilet. Versions of that were already widespread in water-closets in middle-class homes, especially in London once a sewage system was constructed. He did refine the throne and obtained appropriate patents but is best known for popularizing toilets in Victorian England. In 1870, he opened the first showroom and even allowed customers to try out the merchandise before purchase. With his name emblazoned on the overhead tanks, he soon became synonymous with the product. For the record, though, the slang term “crap” traces back to Middle English.
4. Flushing toilets appear as early as settlements in the Indus Valley of 2,500 B.C.E., though antecedents have been found back to the Neolithic period. For that matter, the oldest toilet is still functioning about 4,000 years after it was built. It’s Knossos, Greece, in a small castle.
5. Toilet paper may have been invented in China in the 6^th Other early wipes included pebbles carried in a sponge on a stick common among ancient Romans; a small bag of pebbles carried by Jews; wool, lace, or hemp for the wealthy or – catch your breath – rags, wood shavings, leaves, dry grass, moss, sand, ferns, plant husks, seashells, corncobs, and, of course, water, by the general populace.
6. Modern commercial toilet paper originated in the 1800s, although Joseph Gayetty is widely credited with introducing the product in the United States in 1857 Gayetty’s Medicated Paper was sold in packages of flat sheets, watermarked with the inventor’s name.
7. A patent for roll-based dispensers was awarded in 1883, and its application extended to toilet paper in 1890 the Scot Paper Company was the first to manufacture what would become the long strips of perforated paper wrapped around a paperboard core found within reach of the majority of toilets.
8. Toilet paper also comes folded as interleaved sheets in boxes, or in bulk for use in dispensers.
9. Colored toilet paper, popular from the 1960s, has largely faded from the marketplace, replaced largely by embossed patterns or color designs. And, as a selling point, “softness” or “fluffiness” is a bonus.
10. The average American uses 141 rolls a year, double the rate in other Western countries or Japan. One factor for the difference is that folks elsewhere use bidets or spray hoses to clean themselves.
