What's great about this setup is that when you're ready to see the answer, you can watch as the colors, shapes, and patterns are manipulated to show you how each illusion is made. You'll probably want to replay some of these mind-benders a few times, too.
Since color is a big factor in some optical illusions, color blindness will affect how deft a person is at solving them. That means women, on average, might be better at seeing through these illusions than men, since men have a color blindness rate of 8 percent (compared to 3 percent for women).
Finland isn't quite the North Pole, but it will be home to a team of gainfully employed Christmas elves this holiday season. As Travel + Leisure reports, the Scandinavian country's Lapland Safaris is looking for elves to get guests into the holiday spirit.
Lapland Safaris is a tourism company that organizes activities like snowmobiling, Northern Lights-gazing, skiing, and ice-fishing. The elf employees will be responsible for leading guests to their buses and conveying important information, all while spreading holiday cheer. The job listing reads, "An Elf is at the same time an entertainer, a guide, and a mythical creature of Christmas."
Each Lapland Safari elf will receive training through Arctic Hospitality Academy prior to starting the job. There, they will learn "the required elfing and communication skills." Training will be conducted in English, but candidates' knowledge of French, Spanish, or German is a plus.
To apply, aspiring elves can fill out and submit this form through Lapland Safaris's website. The gig lasts from November 2018 to the beginning of next year, with employees having the option to work at any of the company's Finnish destinations (Santa's workshop is unfortunately not included on the list).
You can buy your cat a fancy bed or perch, but when it comes right down to it, your feline friend is probably going to be more eager to curl up in the cardboard box that it arrived in. So why not just cut out the part where you spend time and money picking out something your cat couldn’t care less about? Just get a really nice box. That’s the premise behind the Purrfect Cat Box, a cardboard box specifically tailored to cats’ needs.
While every cat is finicky in his or her own way, almost all cats love a good cardboard box. (Seriously, it’s science.) Squeezing into a cozy box makes cats feel protected, and, since cats like warmer temperatures, the insulating cardboard also helps keep them at their preferred level of toasty.
Designed by Colorado-based inventor Scott Salzman, the Purrfect Cat Box is made to be just the right size for ultimate kitty comfort. At about the size of a shoebox, it’s big enough for most cats to squeeze into without being cramped—though Salzman doesn’t specify whether it will work for big breeds like Maine Coons—but small enough that they still feel protected inside. It has a small cutout in the front to allow your cat to peek his head outside the box, and, most importantly, to get in a really good chin scratch.
While we humans might find cardboard cars or cardboard Taj Mahal replicas adorable, most cats just want a plain box that makes them feel safe and comfortable. The geometric-patterned Purrfect Cat Box walks the line between utilitarian and chic, making the empty cardboard box in your living room a little bit less of an eyesore.
Plus, it’s cardboard-priced. At $6 a box, it's about what you'd pay to have a regular cardboard box full of anything from Amazon delivered to your door, but it’s still inexpensive enough that if your cat destroys it, it’s easy enough to throw in the recycle bin and get a new one.
