Sticky Notes On a Roll Let You Decide How Much You Need

You can already get sticky notes in a few different sizes, but for those who want even more control, you can now get them on an endless roll—letting you tear off the perfect size as needed. After all, some days you just need a few groceries, while others you need to completely restock the pantry.

Available in yellow, blue, or pink, the Pensée (French for "thought") includes sixteen feet of sticky notes in a plastic dispenser complete with a perforated cutter. And the entire back of the roll is covered in a low-tack adhesive, which means wherever you stick it, it's going to stay put until you tear it off. They're just $9 a roll—and the handy grid that helps keep your handwritten notes neat and tidy is included at no extra charge. More here.

World's Thinnest Mechanical Watch Is as Thick as Two Stacked Quarters

You don't think it's only laptop, tablet, and smartphone designers that go the extra mile to make their devices thinner and thinner do you? Watch makers are constantly battling each other for the same notoriety, and now Piaget has reclaimed the title of 'world's thinnest mechanical watch' with its new Altiplano 38mm 900P that measures in at 3.65mm—making it thinner than many digital alternatives.

Snatching the title from Jaeger-LeCoultre, Piaget managed to shave a full 0.4mm off the thickness of the previous record holder. But the company's watchmakers did it in a very clever way. Normally a mechanical watch features a movement—all the gears and mechanisms that make it tick—inside a case. But with the Altiplano 38mm 900P, the movement is built right into the actual watch's body.

So the watch is just as much a technological and engineering achievement as it is comfortable to wear. Every single one of the Altiplano 38mm 900P's 145 components had to be manufactured with extreme levels of precision, which, not surprisingly, contributes to its wallet-thinning price tag. When available, the watch will sell for between $20,000 and $30,000, but eventually you can expect to see the innovations that made it possible trickle down to other more affordable pieces.

A Full-Size Hybrid Vacuum You Can Charge By USB

When you hear the words 'vacuum' and 'USB' used in the same sentence, you probably picture a tiny keyboard cleaning tool with barely enough power to suck up crumbs. ButPanasonic's hybrid MC-HS700G—now available in Japan—is a full-sized vacuum cleaner strong enough to lift a bowling ball that can also be charged from a USB port giving you up to 20 minutes of suction without a tether to a wall outlet.

For most of your indoor cleaning needs you'll want to keep the MC-HS700G plugged into an AC outlet to take full advantage of its dust sensor, cyclone-action suction, and built-in headlights for spotting dirty areas on your floor. But for cleaning your car, or areas in your home too far from an outlet, the vacuum's rechargeable battery boasts up to 20 minutes of cleaning on a single charge.

Of course, that's with minimal suction. Battery life dwindles to a mere six minutes at full power, so you may want to reinstate that 'no eating in the car' rule. And the vacuum is a hefty $700, making it more expensive than even Dyson's high-end models. But looking over at the tangle of cables on the floor, a rechargeable vacuum that can outperform a dustbuster and share our smartphone's charger is still very, very tempting. More here.

Insane Seattle Bus Crash Captured On Google Street View

Fansite Google Street View World today found that Google Maps has a Street View pictureof a Northwestern Trailways charter bus hanging somewhat precariously over Interstate 5 following a crash.

No, it's not a fake. According to TV station KATU, this happened back in December 2008. They called it a "bizarre incident" in which two charter buses collided while nosing down an icy Seattle hill, sending both of them crashing through a metal railing above the freeway. The bus in the photo hang 30 feet above the Interstate before it was towed to safety.

The Google camera car must have just been in the right place at the right time, I guess. More here.

You'll Actually Be Excited For Snow With This Gorgeous Toboggan

Is there anything more soul crushing than waking up and checking the weather on your phone, only to discover that there are inches of snow outside waiting to complicate your morning commute? Snow in the forecast doesn't always have to be a letdown, though. With this steam-bent wooden toboggan from Lucky Bums, you'll embrace every flake that falls.

Plastic sleds with brakes and steering have come to dominate snow-covered hills over the years, but there's just nothing as thrilling as climbing onto an old-school wooden toboggan, lining up your path of descent, and then hoping you won't hit anything on the way down. If you do, this made-in-the-USA toboggan's padded seat should help you ride out the worst of it.

At $200, it's certainly more expensive that other sledding options you can get your hands on. But remember, like a set of skis, with a little bit of wax a wooden toboggan can send you rocketing down a hill, leaving other higher-tech sledders eating your snowy dust. More here.

Apparently People Will Buy Cans of French Air for $7.50

Money doesn't grow on trees. You can't get something for nothing. There's no such thing as a free lunch. Except all of these cliches are apparently false, because Antoine Deblay, a student who lives in southwest France is actually making money selling cans of air from his town.

For €5.50, or about $7.50, Deblay is shipping 250ml cans of air called "Air de Montcuq" for his hometown. This summer he raised about $1,000 on KissKissBankBank, a French crowdfunding site, which allowed him to make a website and get the tins/packaging he needed. Deblay told Business Insider that in the first three weeks he received a thousand orders and has already made thousands of dollars with a 60 percent profit margin.

The appeal of the cans comes from a pun that is inherent in the name of Deblay's town. Montcuq can be mispronounced "mon cul" or "my ass," meaning that "Air de Montcuq" can be translated as "the wind of my ass." Novelty gift? Sure, why not.

Because he apparently is not afraid of taking the whole thing too seriously, Deblay is only selling 10 liters of air per week so he doesn't put a strain on his supply, and when he hits that limit he puts a warning on the website that orders are done for the week. Deblay told Business Insider, "Of course I knew it was going to sell, but not so much in so little time!" Of course!  More here.

Researchers Discover Huge Freshwater Reserves Under Ocean Floors

As earth's population surges, mankind faces an increasingly limited supply of fresh water. Thankfully, Australian scientists report this week that they've found vast new fresh water supplies. Unfortunately, it's in one of earth's least accessible places: under the ocean floor.

Published in this week's Nature, the research compiles mounting evidence that fresh groundwater reserves exist off the shores of Australia, China, North America and Africa. The researchers estimate that 500,000 cubic kilometers of fresh water is trapped in aquifers under the ocean floor — more than 20 times the volume of water in all five Great Lakes.

Getting to the water without contaminating it presents an enormous challenge. But with 40% of the world's population already living in conditions of water scarcity, it may prove to be necessary. More here.

Mind-Boggling Spherical Gear Made from 3D-Printed Moving Parts

Proxy describes the project as just "the first in a series of kinetic, 3D-printed objects designed to explore the limits of 3D printing as an art form":

Created in a one­-shot fabrication process, Mechaneu #1 features an elaborate network of interlocking gears and support structures. Spin one gear and the entire sphere is catalyzed with the rotation. The effect is mesmerizing, a visualization for the eye and a tactile experience for the hands. The Mechaneu design explores the limit case of commercial 3D printing; all aspect of the design are calibrated to the minimum thicknesses and maximum detail levels.

But it's the insane, nested spherical rotation of this thing—or, rather, the fact that it works, and that it came from a 3D printer—that blows my mind.

Avoid Injuries With Smart Sneakers That Tell You How To Run Properly

A daily run can be great for your health and fitness, but it can actually be harmful too if not done properly. Of course the right shoes are an important part of the formula, especially thissensor-laden pair developed by the Fraunhofer Institute which provide real-time feedback on your running style, and how to improve it.

So what makes these sneaks so smart? Built into their sole is a biometric sensor working alongside an accelerometer and GPS hardware. Together they collect data on the runner's speed and technique, and transmit it to a smartphone app via Bluetooth which analyzes the information and makes suggestions to improve the wearer's running style or routine.

One day it might suggest you try rolling off your foot differently to improve your stride, while others it might recommend running on a softer surface like grass. The shoes and software can even make intelligent recommendations on when you need to give your feet a break. The only feature that might be lacking is giving you the motivation to get off the couch and out the door to begin with. More here.

The Navy Just Launched a Drone from a Submarine—While Underwater

If you thought launching a drone from an aircraft carrier was impressive, you're going to be blown away by this: After six years of development, the U.S. Naval Research Laboratory has successfully launched a drone from a submerged submarine.

That's right. A submerged submarine. Submerged under the ocean. The picture above is real: a composite of time-lapse photos taken during the launch. You can see the wings swing out like a pair of scissors as the drone takes to the sky.

The U.S. Naval Research Laboratory really outdid themselves this time. Their Experimental Fuel Cell (XFC) unmanned aerial system was just fired from the torpedo tube of the USS Providence. The so-called Sea Robin launch vehicle system then floated to the surface, where an all-electric, fuel cell-powered drone with foldable wings took to the sky where it performed an hour-long test flight before landing at the Naval Sea Systems Command Atlantic Undersea Test and Evaluation Center (AUTEC) in the Bahamas. Pretty cool, huh?

Well, this is just the beginning. The XFC launch doesn't come as a huge surprise because we've known for a few months now that DARPA is working on a submarine "mothership"that can launch both unmanned aerial vehicles and unmanned underwater vehicles—all kinds of drones. Dubbed as the Hydra program, this initiative will enable sailors to send remotely piloted, and someday perhaps fully autonomous, craft into battle zones virtually undetected. It'll also scare the pants off of unsuspecting fisherman. More here.

iPhone Anamorphic Lens Lets You Shoot Wider Than Widescreen

Even though 35mm film dominated the film industry for years and years, the majority of movies released to theaters were much wider than the stock's 4:3 aspect ratio. But instead of sacrificing resolution and simply cropping off the top and bottom of a frame to make it widescreen, filmmakers used special lenses that squeezed a wider vista onto the 35mm film stock, and then unsqueezed the images when they were being projected. They were known as anamorphic lenses, and soon you'll be able to get one for your iPhone.

What looks like one of the many external lenses you can get for your smartphone is actually one of the first to do an anamorphic squeeze on your footage, letting you shoot video that's approximately 33 percent wider than the iPhone's standard field of vision.

So if you're shooting video in an old-school 4:3 aspect ratio, when the footage was unsqueezed in your video editor it would have a wider 16:9 vista. And if you're shooting in 16:9 to start with, the resulting footage would have an even wider and more majestic 2.4:1 aspect ratio. For still images the iPhone's panoramic mode easily accomplishes this, but this is currently the only way to pull it off for video.

The anamorphic adapter lens is currently raising funds on Kickstarter, and with a pledge of $85 or more you can claim one of the first production units when they're available sometime closer to March of next year. More here.

Great Gifts You Can 3D Print

The best gifts are the ones that aren't obvious. Oh you're going to get your sister another pair of earrings? Nah. This time you should go for a set that were 3D printed instead. In order to wow your family and everyone on your list this year, here's are some magical presents that came out of a printer.

Now, you may be thinking, but I don't have a 3D printer. But no printer is no problem. You can easily order something that has already been designed and 3D printed for you. So now that you know how easy it is, what are you going to print for your friends and family? Maybe you can find some inspiration here.

Spin Around a Mountain in Super Speed like Superman

Things that usually spin really, really fast: a top, the wheel of fortune wheel, other wheels, circular objects, knobs and other things of that nature. Not a mountain! Well, unless you're Superman and can fly around it. Newsflash: we're not Superman. However! Kevin Parry and Andrea Nesbitt of Candy Glass Productions might be. They created a mountain spinning flyby effect in a sick hyperlapse of Mt. Hood.

Nesbitt told PetaPixel that creating a hyperlapse of the spinning mountain took a lot of careful planning along with "miles and miles of hiking, and some terrifying driving/exploring". I think it was totally worth it.

A Tiny Stamp Brands Your Can To Make Sure No One Steals Your Drink

Is there anything worse than being at a party and having someone steal your drink? Sure! Taking a long swigg on a can only to realize it isn't yours. But now you can avoid both situations with this keychain-sized stamp that lets you brand an aluminum can with a permanent message, leaving no debate as to its ownership.

The aptly named CanStamp features a set of raised letters spelling out messages like mine, in use, fuel, and 1 more. And branding your beverage is as easy as pressing that stamp—and its message—it into the ridge just below the top of an aluminum can. Admittedly debates over ownership could flare up if more than one person brings the $8 CanStamp to a party, so you might want to skip this one until they come out with a version you can personalize with your name, or a more specific threat.

Australia's Using Pop Radio to Track Space Junk

Space junk is a serious problem: it threatens satellites and spacecraft, and can plummet unpredictably to earth. Australia's Murchison Widefield Array is a high-sensitivity radio telescope that tracks space debris as small as 1 meter across, by observing how the objects reflect FM signals from Australian radio stations. It's listening to pop music from space.

The array, part of western Australia's Murchison Radioastronomy Observatory, was built as a precursor to the proposed Square Kilometre Array being jointly undertaken by Australia and South Africa. As it stands right now, the Murchison Widefield Array consists of 2,048 individual antennas arranged in 128 four-by-four tiles. A single tile is pictured above.

When FM broadcast radio signals traveling out into space encounter debris, some of the radio waves are reflected back toward earth. The Murchison Widefield Array can pick up signals from objects as far as 620 miles away. So the next time you hear Gotye or Keith Urban on the radio, just think — in Australia, they're helping monitor space junk. More here.

A Paper Shopping Bag That Transforms Into a Hanger Back Home

If you get lucky, the clothing store where you bought that new sweater or shirt might toss in the plastic hanger it was on free of charge. Otherwise, you'll have to scrounge one up yourself—at least until this wonderful redesign of the shopping back becomes a reality. With a few folds the Hangbag transforms into its own hanger, strong enough to support everything short of a lead-lined suit.

The bag is the brainchild of designers Parin Sanghvi, Shruti Gupta, and Mohit Singhvi, and it takes the less-used reuse approach. Instead of encouraging shoppers to just toss the sack in their recycling bin, it includes instructions on how to use some basic origami techniques to turn it into a very functional hanger. And while it might not be the prettiest hanger in your closet, the important thing is that it's free, it works, and it finally makes paper bags as useful as their plastic counterparts. More here.

Ugh, Who Invited Math To the Rubik's Cube Party?

The simplicity of the Rubik's Cube puzzle is what makes it so devilishly difficult to solve at times. It's just a bunch of colored squares, but getting them to group together can be a life's pursuit for many people. So who in their right mind thought that taking the Rubik's Cube formula and adding mathematical patterns of numbers into the mix was a good idea? Clearly someone with a deep love of mathematics, or a sincere hatred for humanity.

At first glance you might assume the rules of Sudoku might come into play here, but they don't. Solving the six sides of this puzzle cube instead requires you to group the numbers into well-known mathematical patterns or collections—including a Fibonacci series, a prime number series, and even the digits of Pi. In other words, unless you've memorized these numberical formations, solving this puzzle will be all but impossible for anyone other than practising mathematicians. But it's great news for anyone with a math professor on their holiday shopping list, and a $20 limit. More here.

Why Your Thanksgiving Meal Makes You Tired

Today, you're gonna shovel one hell of a lot of turkey and pie down your throat, then collapse in a food-coma in front of the TV. But why does your huge meal make you feel like snoozing?

As you'd expect, science has some answers. It turns out that there are two big factors that make you fancy a snooze soon after the pumpkin pie is polished off.

First, when the food starts to arrive in your belly, the activity of the parasympathetic nervous system increases and the activity of the sympathetic nervous system decreases. Huh, what does that mean? Well, the sympathetic nervous system provides our fight-or-flight response. The parasympathetic system gets your organs ready for digestion. Basically, your body wants you to stay still in order to sort out the contents of your stomach. That's why you choose not to move too much after your meal.

Next, when you start digesting your food, you get a big rush of glucose into your blood stream. If you don't have diabetes, your body creates insulin to help the body's cells absorb the glucose. The insulin works by affecting the uptake of a bunch of amino acids in the body — stick with me here! — except for one called tryptophan. So the concentration of tryptophan increases relative to other amino acids. Turns out that in the brain, tryptophan is converted to serotonin, which is itself converted to melatonin — both of which result in sleepiness.

Voila! Your nervous system and your brain both want you to sleep. So I say go with it.

Incidentally, there's a myth that turkey contains a lot of tryptophan. That's kinda rubbish, though, as turkey doesn't contain any more than chicken, beef, or plenty of other meats. So don't blame the turkey too much. Blame your gluttony instead. More here.

A Multipurpose Key That Will Unlock Your Inner MacGyver

In addition to opening doors, that set of keys in your pocket also serves as makeshift knives, prybars, and even ice scrapers. But why risk accidentally bending a key and losing access to your home when this key-sized multi-tool can do so much more?

What you're looking at here is actually five tools in one including a box cutter, a bottle opener, a metric and imperial ruler, a multi-sized wrench, and a flat-head screwdriver. But that's just its official uses. With enough imagination this can come in handy for countless other uses, even gaining access to your home if your actual key's gone MIA.

And it's just $5. Break that down and you're paying just a buck for every tool this little wonder emulates. You can't even buy a decent screwdriver for that much, and especially not one that will sit as comfortably in your pocket as this one. More here.

Chrome Is Finally Getting Hands-Free "Ok Google" Search

Even if your family gets bored and stops listening to you this Thanksgiving, at least your computer will still have open ears. Just in time for the holidays, Google has officially released voice recognition for Chrome browsers in the form of a Chrome extension.

To enable the new Voice Search Hotword ability, all you need to do is head to the Chrome Web Store and download the extension. At that point, you'll be able to talk to your laptop totally hands-free, like it was a Moto X or an Xbox One. To activate the feature, simply say "Ok Google" followed by your search or command. You know the drill.

Whether you need to start a timer, look up unit conversions, or dates, or whatever, Google's voice command will listen, and relay back to you out loud. See, the holidays don't have to be so lonely after all, kind of. More here.
