After Spending Months Submerged, This Drone Can Launch From the Ocean

From remote villages to the tops of skyscrapers, there aren't many places a drone can't reach. Now, there's a chance you may even run into one while scuba diving in the ocean.

As reported by Popular Science, the CRACUN drone (pronounced Kraken) is a "Corrosion Resistant Aerial Covert Unmanned Nautical System” developed by researchers at the Johns Hopkins Applied Physics Laboratory. The 3D-printed, watertight craft is designed to stay submerged hundreds of feet beneath the sea for months at a time before eventually breaking through the surface and taking flight.

To keep it protected from the corrosive effects of salt water, parts of the body are coated with a commercial sealant that's commonly used in marine applications. The prototype was able to fly through the air successfully after spending two months underwater.

The research team has yet to reveal the intended applications for such a device, but they say the low production costs “makes it expendable, allowing for the use of large numbers of vehicles for high-risk scenarios.” According to Motherboard, the U.S. secretary of the Navy even went out of his way to praise the project. You can watch the CRACUN launch from the water in the video above.

Acquiring a KitchenAid stand mixer is considered a home cook's rite of passage for a reason—while endlessly useful for baking, it's also one of the more expensive gadgets you can have on your countertop. If the stand mixer's usual $260 price tag has turned you off in the past, now's the time to reconsider adding one to your kitchen. According to Cooking Light, Target is offering the standard silver 4.5-quart KitchenAid stand mixer for a special price of $190.

The standard silver KitchenAid is the classic model. It comes with a dough hook, a flat beater, and a wire whisk that can be set to one of 10 different speeds—perfect for kneading dough or whipping cream without straining an arm muscle. And if you want to spend the money you save from the deal on even more kitchen tools, you can spring for one of the many accessories that attach to the front of the mixer, like the pasta maker, the veggie spiralizer, or the meat grinder. The standard mixer, like all of KitchenAid's countertop appliances, comes with a one-year warranty.

The silver mixer isn't the only KitchenAid product on sale through Target. The KitchenAid Ultra Power Plus mixer, which normally retails for $350, is currently available for $280. With that item, buyers will have a variety of colors to choose from, including ice blue, cobalt, and red.

Looking for an even cheaper way to upgrade your kitchen? There are plenty of game-changing cooking gadgets out there that won't drain your bank account.

The Fun Optical Illusion You Can Make With Your iPhone X

You can use the iPhone X’s powerful depth sensor for more than just face recognition. The technology also allows you to create wild optical illusions on your phone. The phone’s 3D camera allowed Swedish artist Peder Norrby to create a depth illusion that makes an image on the phone look 3D, as Co.Design reports.

The app Norrby created with ARKit face tracking, TheParallaxView, uses a technique called trompe l’oeil, a style you might have seen before in the form of pavement art. It uses hyperrealistic art to give the illusion that a 2D image is really 3D.

The eye tracking makes the image move as the camera does, making it look like you’re manipulating a 3D object, either one that recesses deep into the phone or pops out from the screen. As Mark Wilson explains on Co.Design, this face tracking “allows the screen to create not just one static 3D illusion, but dozens a second, tricking your mind into believing that there’s a whole other world behind the screen of your phone.”

It’s a monoscopic effect, according to Norrby, so the illusion works particularly well in video form, but in person, you’ll need to close one eye to make it work to the same degree.

You can see how it works in the video below. Norrby has submitted the app to Apple’s App Store, but it’s still pending approval. He’s also planning on submitting the source code for developers, which means that anyone could incorporate it into their apps—which we imagine could lead to some pretty amazing video games.
