This Mind-Boggling Puzzle Has No Beginning or End

Most jigsaw puzzles present assemblers with a clear challenge: Arrange the pieces just right until you’ve recreated the picture on the box. If puzzles appeal to your logical side, you may have a hard time completing the Infinite Galaxy Puzzle. The pieces are specially designed to fit together in any direction with no boundaries to contain them.

The edgeless puzzle was made possible using “math, science, and lasers,” according to the creators. The geometric concept that inspired the idea is called a Klein bottle, a theoretical 3D shape that’s mathematically identical inside and out.

Because both sides of the puzzle feature a picture of the Milky Way’s galactic core, it has no fixed up or down. The image wraps around from one surface to the other making it impossible to see the whole thing at once. When putting the puzzle together, pieces on the outside can be flipped over and transferred to the opposite side of the image, giving assembly a never-ending effect.

One puzzle includes 133 pieces laser-cut from birch plywood and costs $120. If you prefer puzzles that leave zero room for creativity, this 1000-color monstrosity from German artist Clemens Habicht is just as maddening.

Kodak’s New Cameras Don't Just Take Photos—They Also Print Them

Snapping a photo and immediately sharing it on social media is definitely convenient, but there’s still something so satisfying about having the printed photo—like you’re actually holding the memory in your hands. Kodak’s new STEP cameras now offer the best of both worlds.

As its name implies, the Kodak STEP Instant Print Digital Camera, available for $70 on Amazon, lets you take a picture and print it out on that very same device. Not only do you get to skip the irksome process of uploading photos to your computer and printing them on your bulky, non-portable printer (or worse yet, having to wait for your local pharmacy to print them for you), but you never need to bother with ink cartridges or toner, either. The Kodak STEP comes with special 2-inch-by-3-inch printing paper inlaid with color crystals that bring your image to life. There’s also an adhesive layer on the back, so you can easily stick your photos to laptop covers, scrapbooks, or whatever else could use a little adornment.

For those of you who want to give your photos some added flair, you might like the Kodak STEP Touch, available for $130 from Amazon. It’s similar to the regular Kodak STEP, but the LCD touch screen allows you to edit your photos before you print them; you can also shoot short videos and even share your content straight to social media.

If you want to print photos from your smartphone gallery, there's the Kodak STEP Instant Mobile Photo Printer. This portable $80 printer connects to any iOS or Android device with Bluetooth capabilities and can print whatever photos you send to it.

All three Kodak STEP devices come with some of that magical printer paper, but you can order additional refills, too—a 20-sheet set costs $8 on Amazon.

Head to any given park on any given sunny summer day, and you’ll likely encounter a people-watcher’s paradise. And to keep us occupied on the rainy days, online watch retailer Watches2U has turned all those sunbathers, joggers, dog-walkers, and skittery squirrels into an entertaining brainteaser.

The left and right images below are almost identical, save for 10 tiny discrepancies that you may not notice at first glance. Once you think you’ve spotted them all (or given up), scroll to the bottom to reveal the answers.

Which type of park-goer are you?Watches2U

As any good Parks and Recreation fan knows, even the smallest park can be a symbol of community and a saving grace for city-dwellers short on yard space. And national parks, like Yellowstone and the Grand Canyon, can be full-fledged vacation spots. They often also help protect wildlife in the region. Great Smoky Mountains National Park, for example, is known as the “salamander capital of the world,” and Theodore Roosevelt National Park is home to hundreds of bison, which were once on the brink of extinction.

In the midst of the current pandemic, a visit to your local park might look a little different than it usually does. Masks and social distancing are musts, and hand sanitizer should flow freely. And if you’re road-tripping a little farther from home, here are some expert tips for doing it safely.
