These Images Can Alter Your Vision For Months

Warning: These images may affect your vision for days or even months if you look too long. The damage isn’t irreparable, though, and the worst possible side effect is that you might start seeing colors a little differently, the Indy100 notes.

It’s called the McCollough effect—named after psychologist Celeste McCollough Howard—and one of the earliest studies of this phenomenon dates back to 1975. Researchers separated 16 people into five groups and showed them two different striped patterns featuring the colors red and green.

After looking at each image for about three minutes, the test subjects then stared at black and white striped grids. That’s when the effect started to set in, and participants reported seeing a pinkish hue in the black and white images. One test group reported that the effect remained in full force after five days, while the other four groups said they still felt a weakened form of the effects three months later.

An earlier study from 1969 found that only the colors green and red produced this effect. There’s no consensus on what causes it, but some scientists believe it’s related to neurons in the visual cortex, according to IFL Science. Others have suggested that the brain tries to “color-correct” what you’re seeing, while a third theory posits that the effect is a symptom of withdrawal caused by the absence of color.

To get your vision back to normal more quickly, it’s recommended that you stare at the two images of the red and green lines, except with the image turned 90 degrees counter-clockwise.

World’s Largest Ouija Board Unveiled in Salem, Massachusetts

If a young Rick “Ormortis” Schreck ever asked a Ouija board if he’d end up making the world’s largest Ouija board, the answer should’ve been yes.

“OuijaZilla,” as it’s affectionately called, weighs 9000 pounds and covers 3168 square feet—as big a footprint as five 18-wheelers. According to Popular Mechanics, the board took 99 pieces of plywood, 20 quarts of black paint, several gallons of deck stain, and one whole year to complete.

It contains all the classic elements of a traditional Ouija board, including the full alphabet, numbers zero through nine, and the words yes, no, and goodbye. Instead of using their fingers to move the planchette across the board, a few people stand inside the 400-pound planchette’s circular cutout and shuffle their way into a seance.

Schreck, a tattoo artist and vice president of the Talking Board Historical Society (TBHS), originally built the giant Ouija board in New Jersey and then transported it to Salem, Massachusetts, where it was reassembled and unveiled to the public on October 12.

The town, notorious for its witch hunts in the late 17th century, seems an especially eerie resting place for yet another spooky piece of America’s history. But it’s actually where Ouija boards were manufactured for years, after Salem-based toy company Parker Brothers bought the rights to the game in 1966. It’s also the town that inspired Schreck’s initial interest in Ouija boards in 1992.

According to the TBHS website, the Brobdingnagian board is nearly 2.5 times larger than the current Guinness World Record holder, and Ripley's Believe It or Not! has bestowed the title of "world's largest Ouija board" on Schreck's creation. It’s also “fully operational,” which hopefully means that you can use it to commune with extra-large dead people.

Wizarding World Gold, a Magical New Harry Potter Subscription Service, Has Arrived

For Potterheads, Christmas just came early. There’s a new Harry Potter subscription service on the market, and it’ll make you feel like you plunged face-first into one of the magical books—not unlike Harry’s frequent forays into the Pensieve.

Engadget reports that Wizarding World Gold is a 12-month commitment, and includes access to all seven Harry Potter ebooks through the Wizarding World app, collectible pin badges, merchandise discounts, and more.

That’s really just the tip of the iceberg-sized rock cake. After signing up, you’ll receive a pin, a print of J.K. Rowling’s sketch of Hogwarts, and a personalized journal called Keys and Curios, designed by the graphic design team behind the Harry Potter and Fantastic Beasts film franchises. It features your name, Hogwarts house, and “enchanted keys” that “unlock hidden secrets” when scanned with the Wizarding World app.

You can also watch Wizarding World Originals, an exclusive video series that delves into the mysteries of the world of Harry Potter; gain early access to collectible merchandise and priority bookings for events like Harry Potter and the Cursed Child, and enjoy magical quizzes and puzzles. You’ll also make the guest list for festivities like the Wizarding World Gold Christmas Party in the Great Hall at Warner Bros.’s Studio Tour London.

If you register now, your welcome gift with the pin, print, and journal will arrive in about two weeks, and your first official subscription box will follow later this autumn. It’s $75 for the entire year, which is quite a bit cheaper than flying off to The Wizarding World of Harry Potter.

If you have any funds left in your Gringotts vault, you can supplement your fantasy-filled subscription with a Harry Potter pop-up book, sock Advent calendar, bathrobe, or even Pandora jewelry.
