It’s fair to say that Richard—an ennobled great-grandson of King Edward III—dying at the Battle of Wakefield in 1460 probably isn’t the most well known of historical facts. But when you retell that story as “Richard Of York Gave Battle In Vain,” then it suddenly becomes a bit more familiar: an obscure occurrence from the early days of the Wars of the Roses has become immortalized as a mnemonic to remember the colors of the rainbow.

But there’s more to mnemonics like this than just remembering colors. From royal wives to birthstones, here are some memory-building sentences to give your general knowledge a boost.

1. “A BIG SECRET CONCEALS HER PAST” // HENRY VIII'S WIVES

Everyone knows the rhyme “divorced, beheaded, died; divorced, beheaded, survived” to remember the fates of Henry VIII’s wives—but which wife matches which fate? Mnemonics used to remember the six wives’ names are tricky, not least because there are three Catherines to contend with (some of whom sometimes have their names spelled with a K rather than a C). But when all else fails, try remembering the appropriately evocative sentence “A Big Secret Conceals Her Past” to help recall the dramatic lives of Catherine of Aragon, Anne Boleyn, Jane Seymour, Anne of Cleves, Catherine Howard, and Catherine Parr.

2. “MOTHER VISITS EVERY MONDAY, JUST STAYS UNTIL NOON” // THE PLANETS

Until the International Astronomical Union downgraded Pluto to a dwarf planet in 2006, the line “My Very Easy Method Just Speeds Up Naming Planets” helped a lot of people remember the order of the planets from nearest to furthest from the Sun. You can still use the same line and drop the P, of course, but with only Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune to recall, how about the eight-word “Mother Visits Every Monday, Just Stays Until Noon.”

3. “HAPPY HENRY LIVES BESIDE BORON COTTAGE” // THE CHEMICAL ELEMENTS

From symbols and atomic numbers to groups and periods, any chemistry student knows there’s plenty to remember when it comes to the periodic table. But when it comes to remembering the names of the elements themselves, how about “Happy Henry Lives Beside Boron Cottage.” That not only helps recall the names of the first half dozen elements (hydrogen, helium, lithium, beryllium, boron, and carbon) but also their chemical symbols (H, He, Li, Be, B, C—so long as you know which elements have two-letter rather than one-letter symbols, of course). But if you want to remember the first 20 elements, you’ll have to remember a bit more about Happy Henry and his friends:

Happy Henry Lives Beside Boron Cottage, Near Our Friend Nelly Nancy MgAllen. Silly Patrick Stays Close. Arthur Kisses Carrie.

From “near” onwards, that’ll help you remember nitrogen (N), oxygen (O), fluorine (F), neon (Ne), sodium (Na), magnesium (Mg), aluminium (Al), silicon (Si), phosphorus (P), sulphur (S), chlorine (Cl), argon (Ar), potassium (K), and calcium (Ca).

4. “SUPER HEROES MUST EAT OATS” // THE GREAT LAKES

Remembering that the names of the five Great Lakes spell the word HOMES is one thing, but when it comes to remembering them in order of size from largest to smallest surface area, try “Super Heroes Must Eat Oats”—Superior, Huron, Michigan, Erie, Ontario. Want to know them from left to right on a map? Swap those superheroes for “Super Man” who, it’s worth remembering, “Helps Every One.”

5. “KING PHILIP CAME OVER FOR GOOD SPAGHETTI” // ZOOLOGICAL TAXONOMY

Unless you’re a zoologist or a taxonomist, you might not need to know the hierarchy of the chief taxonomical classifications all too often (depending on how difficult your local pub quiz is, of course). But when need be, just remember that time when “King Philip Came Over For Good Spaghetti,” or that “Kings Play Chess On Fine Glass Surfaces,” and you’ll easily recall the order of kingdom, phylum, class, order, family, genus, and species.

6. “BIG GORILLAS EAT HOTDOGS, NOT COLD PIZZA” // CENTRAL AMERICAN COUNTRIES

If you struggle to remember the names of the seven countries of Central America, remember that “Big Gorillas Eat Hotdogs, Not Cold Pizza”: Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, and Panama.

7. “EVERY GOOD BOY DESERVES FAVOR” // TREBLE CLEF NOTES

In music, the mnemonic “Every Good Boy Deserves Favor” (or “Football,” or “Ferraris,” depending on what your incentive of choice is) is such a well known method for remembering the notes on the lines of the treble clef that it’s been immortalized as both the title of a Tom Stoppard play and a 1971 album by the Moody Blues. If you’ve ever had a piano lesson you’ll also know that the four spaces in between the lines spell FACE.

8. “ALL COWS EAT GRASS” // BASS CLEF NOTES

As for the bass clef? “All cows eat grass” is a neat way of remembering the four bass spaces ACEG, while the five lines either side of them can be used to spell out the fact that “Good Boys Deserve Favor Always.”

9. “FATHER CHARLES GOES DOWN AND ENDS BATTLE” // THE ORDER OF THE SHARPS

Another musical order worth remembering is that of the sharps added to successive keys. So while the key of C major has no sharps at all, G major has an F sharp; D major has both an F and C sharp; A major has an F, C, and G sharp; E major adds a D sharp into the mix; B major adds an A sharp; the key of F sharp major needs an E sharp; and all notes are sharped in the key of C sharp major, which adds a final B sharp into the mix. All told, it’s a bit of a muddle on its own, but if you bear in mind that “Father Charles Goes Down And Ends Battle”—or that “Fat Cats Go Down Alleys Eating Birds”—then you can’t go far wrong.

10. “GOOD DOGS ALWAYS EAT” // VIOLIN STRINGS

From lowest to highest the notes to which the strings on a violin are tuned spell out “Good Dogs Always Eat.”

11. “ELEPHANTS AND DONKEYS GROW BIG EARS” // GUITAR STRINGS

Memorize that sentence to remember the notes of the six strings in a standard guitar tuning.

12. “GREAT ACTORS ALWAYS DEVELOP EVERY POSSIBLE RESOURCE, PERFECTLY SEIZING OPPORTUNITIES TO TRIUMPH” // BIRTHSTONES

Keep the above sentence in mind, and you should be able to remember the order of the 12 traditional birthstones, garnet (January), amethyst (February), aquamarine (March), diamond (April), emerald (May), pearl (June), ruby (July), peridot (August), sapphire (September), opal (October), topaz (November), and turquoise (December).

13. “ANOTHER TOM CAT, CAUGHT NAPPING” // ROMAN EMPERORS

Need to remember the first batch of Roman emperors? “Another Tom Cat, Caught Napping,” put another way, is Augustus, Tiberius, Caligula, Claudius, and Nero.

When it comes to furnishing your kitchen with all of the appliances necessary to cook night in and night out, you’ll probably find yourself running out of counter space in a hurry. The ChopBox, which is available on Indiegogo and dubs itself “The World’s First Smart Cutting Board,” looks to fix that by cramming a bunch of kitchen necessities right into one cutting board.

In addition to giving you a knife-resistant bamboo surface to slice and dice on, the ChopBox features a built-in digital scale that weighs up to 6.6 pounds of food, a nine-hour kitchen timer, and two knife sharpeners. It also sports a groove on its surface to catch any liquid runoff that may be produced by the food and has a second pull-out cutting board that doubles as a serving tray.

There’s a 254nm UVC light featured on the board, which the company says “is guaranteed to kill 99.99% of germs and bacteria" after a minute of exposure. If you’re more of a traditionalist when it comes to cleanliness, the ChopBox is completely waterproof (but not dishwasher-safe) so you can wash and scrub to your heart’s content without worry. 

According to the company, a single one-hour charge will give you 30 days of battery life, and can be recharged through a Micro USB port.

The ChopBox reached its $10,000 crowdfunding goal just 10 minutes after launching its campaign, but you can still contribute at different tiers. Once it’s officially released, the ChopBox will retail for $200, but you can get one for $100 if you pledge now. You can purchase the ChopBox on Indiegogo here.

11 Fascinating Facts About Tamagotchi

Tamagotchi is the toy that launched a thousand digital pet competitors.

They blooped and beeped and ate, played, and pooped, and, for ‘90s kids, the egg-shaped Tamagotchi toys were magic. They taught the responsibility of tending to a “pet,” even though their shrill sounds were annoying to parents and teachers and school administrators. Nearly-real funerals were held for expired Tamagotchi, and they’ve even been immortalized in a museum (of sorts). Here are 11 things you should know about the keychain toy that was once stashed in every kid’s backpack.

1. The idea for the Tamagotchi came from a female office worker at Bandai.

Aki Maita was a 30-year-old “office lady” at the Japanese toy company Bandai when inspiration struck. She wanted to create a pet for kids—one that wouldn't bark or meow, make a mess in the house, or lead to large vet bills, according to Culture Trip. Maita took her idea to Akihiro Yokoi, a toy designer at another company, and the duo came up with a name and backstory for their toy: Tamagotchis were aliens, and their egg served as protection from the Earth’s atmosphere. They gave prototype Tamagotchis to high school girls in Shibuya, and tweaked and honed the design of the toy based on their feedback.

2. The name Tamagotchi is a blend of two Japanese words.

The name Tamagotchi is a mashup between the Japanese words tamago and tomodachi, or egg and friend, according to Culture Trip. (Other sources have the name meaning "cute little egg" or "loveable egg.")

3. Tamagotchis were released in Japan in 1996.

Bandai released the Tamagotchi in Japan in November 1996. The tiny plastic keychain egg was equipped with a monochrome LCD screen that contained a “digital pet,” which hatched from an egg and grew quickly from there—one day for a Tamagotchi was equivalent to one year for a human. Their owners used three buttons to feed, discipline, play with, give medicine to, and clean up after their digital pet. It would make its demands known at all hours of the day through bloops and bleeps, and owners would have to feed it or bathe it or entertain it.

Owners that successfully raised their Tamagotchi to adulthood would get one of seven characters, depending on how they'd raised it; owners that were less attentive faced a sadder scenario. “Leave one unattended for a few hours and you'll return to find that it has pooped on the floor or, worse, died,” Wired wrote. The digital pets would eventually die of old age at around the 28-day mark, and owners could start fresh with a new Tamagotchi.

4. Tamagotchis were an immediate hit.

The toys were a huge success—4 million units were reportedly sold in Japan during their first four months on shelves. By 1997, Tamagotchis had made their way to the United States. They sold for $17.99, or around $29 in today's dollars. One (adult) reviewer noted that while he was "drawn in by [the Tamagotchi's] cleverness," after several days with the toy, "the thrill faded quickly. I'm betting the Tamagotchi will be the Pet Rock of the 1990s—overwhelmingly popular for a few months, and then abandoned in the fickle rush to some even cuter toy."

The toy was, in fact, overwhelmingly popular: By June 1997, 10 million of the toys had been shipped around the world. And according to a 2017 NME article, a whopping 82 million Tamagotchi had been sold since their release into the market in 1997.

5. Aki Maita and Akihiro Yokoi won an award for inventing the Tamagotchi.

In 1997, the duo won an Ig Nobel Prize in economics, a satiric prize that’s nonetheless presented by Nobel laureates at Harvard, for "diverting millions of person-hours of work into the husbandry of virtual pets" by creating the Tamagotchi.

6. Tamagotchis weren't popular with teachers.

Some who grew up with Tamagotchi remember sneaking the toys into school in their book bags. The toys were eventually banned in some schools because they were too distracting and, in some cases, upsetting for students. In a 1997 Baltimore Sun article titled “The Tamagotchi Generation,” Andrew Ratner wrote that the principal at his son’s elementary school sent out a memo forbidding the toys “because some pupils got so despondent after their Tamagotchis died that they needed consoling, even care from the school nurse.”

7. One pet cemetery served as a burial ground for expired Tamagotchi.

Terry Squires set aside a small portion of his pet cemetery in southern England for dead Tamagotchi. He told CNN in 1998 that he had performed burials for Tamagotchi owners from Germany, Switzerland, France, the United States, and Canada, all of whom ostensibly shipped their dead by postal mail. CNN noted that "After the Tamagotchis are placed in their coffins, they are buried as mourners look on, their final resting places topped with flowers."

8. There were many copycat Tamagotchi.

The success of the Tamagotchi resulted in both spin-offs and copycat toys, leading PC Mag to dub the late ’90s “The Golden Age of Virtual Pets.” There was the Digimon, a Tamagotchi spin-off by Bandai that featured monsters and was marketed to boys. (There were also Tamagotchi video games.) And in 1997, Tiger Electronics launched Giga Pets, which featured real animals (and, later, dinosaurs and fictional pets from TV shows). According to PC Mag, Giga Pets were very popular in the United States but “never held the same mystique as the original Tamagotchi units.” Toymaker Playmates's Nano Pets were also a huge success, though PC Mag noted they were “some of the least satisfying to take care of."

9. Rare Tamagotchis can be worth a lot of money.

According to Business Insider, most vintage Tamagotchis won't fetch big bucks on the secondary market. (On eBay, most are priced at around $50.) The exception are rare editions like “Yasashii Blue” and “Tamagotchi Ocean,” which go for $300 to $450 on eBay. As Complex notes, "There were over 40 versions (lines) of Tamagotchi released, and each line featured a variety of colors and variations ... yours would have to be one of the rarest models to be worth the effort of resale."

10. A new generation of Tamagotchis were released in 2017 for the toy's 20th anniversary.

In November 2017, Bandai released a 20th anniversary Tamagotchi that, according to a press release [PDF], was "a first-of-its-kind-anywhere exact replica of the original Tamagotchi handheld digital pet launched ... in 1996." However, as The Verge reported, the toys weren't an exact replica: "They're about half the size, the LCD display is square rather than rectangle, and those helpful icons on the top and bottom of the screen seem to be gone now." In 2019, new Tamagotchis were released; they were larger than the originals, featured full-color displays, and retailed for $60.

11. The original Tamagotchi’s sound has been immortalized in a virtual museum.

The Museum of Endangered Sounds is a website that seeks to immortalize the digital sounds that become extinct as we hurtle through the evolution of technology. “The crackle of a dial-up modem. The metallic clack of a 3.5-inch floppy slotting into a Macintosh disk drive. The squeal of the newborn Tamagotchi. They are vintage sounds that no oldies station is ever going to touch,” The Washington Post wrote in a 2012 profile of the museum. So, yes, the sound of that little Tamagotchi is forever preserved, should it someday, very sadly, cease to exist completely.
