News: Are Diamonds Forever?
As Theo Gray of Gray Matter demonstrates below, contrary to what the ads may say, diamonds CAN expire. Especially when attacked with a blow torch and liquid nitrogen. Gray says:
As Theo Gray of Gray Matter demonstrates below, contrary to what the ads may say, diamonds CAN expire. Especially when attacked with a blow torch and liquid nitrogen. Gray says:
PopSci's Gray Matter demonstrates again and again what the layman should absolutely Not Try at Home. Which is precisely what makes Gray's experiments so fun. Remember when the mad scientist fully submerged his hand in liquid nitrogen? Today's demonstration also plays with what is (quite reasonably) assumed to be extremely dangerous and painful: torching the human hand.
Here at WonderHowTo, we love science. And of course, explosions. So, naturally we find Gray Matter's demonstration of fiery hydrogen bubbles pretty awesome. But the most interesting part is the reason behind the demonstration. Did you know the same gas that heats your house can also make it explode? Gray Matter explains why:
If you're a tuna lover, but aren't really fond of the raw sushi tuna variety, this could be the perfect blend of both worlds. Tuna enthusiasts no longer have to have it one way or the other… go in-between with a lightly torched tuna meal. Lightly torched tuna (yes, a blowtorch is used) joins a sweet, salty and tangy vinaigrette with fresh herbs and anchovies. Piled atop vibrant radishes, scallions and peas, the dish was beautifully assembled and presented to an appreciative farmers' market cr...
Oscar the cat is one lucky feline. After losing his two hind legs in a combine harvester, his loving owners had Oscar outfitted with two prosthetic paws, or metallic pegs to be more specific. This revolutionary veterinary procedure is nothing to scoff at - biomedical engineering experts and a neuro-orthopedic surgeon were both called in to create the world's first bionic cat. Via BBC:
It's been almost a century since we've last seen Kid Icarus start in his own game! The result of Project Sora, Kid Icarus will be released for the Nintendo 3DS!
These are great times. It is about time advertisers invaded our video games in the same way they do our driving (billboards), walking (fliyers, posters), and our private home (emails, bulk mail, text messages).
Is Daily Sunscreen Application Dangerous? Since birth, I've been lathered in the sunscreen anytime I venture into the sun. It's what comes with being the freckled spawn of two parents with (benign) skin cancer. Always a fan of the outdoors, my skin has seen lots of sun. You can tell, too. From the lifeguarding, surfing and soccer tournaments, I've definitely notched dozens of sunburns. To protect my skin daily, every morning I apply a moisturizer that includes an SPF 15 sunscreen.
MacGyver. How can he not be a WonderHowTo hero?
Chemical engineers at Cornell have created a small device that may one day turn troops into real life spider-men. The device would cradle in the palm of the hand, allowing troops to scale walls. It uses an adhesive inspired by the Floridian leaf beetle, an insect that "can adhere to leaves with power 100 times stronger than its own body weight".
Images of BlackBerry's two upcoming Android phones have surfaced. Reportedly named "Hamburg" and "Rome," keeping with the company's tradition of using cities as code names for its devices, the images come from BlackBerry Central founder Dylan Habkirk (via Times News UK/GSMArena).
Mobile World Congress is just around the corner, and if patterns stay consistent, Samsung will be unveiling their newest member of the Galaxy line, the Galaxy S5.
Staples may be an office staple when it comes to joining sheets of paper together, but they're a pain in the ass if you ask me. They're annoying to take out, you can't shred 'em, and they eventually loosen up. Plus, staplers tend to stop working right when you need them the most.
Enjoy the deliciousness of a peanut butter sandwich without the artificial chemicals that comes in store-bought jars. To make your own peanut butter at home, all you need are pre-roasted peanuts, peanut oil, and a little bit of salt and sugar.
If people are constantly asking you why you look so tired, then maybe it's time to get rid of the puffy dark circles under your eyes.
However much you love your summer barbecue parties, you probably won't be going through your entire bag of charcoal briquettes anytime soon. So, take advantage of your charcoal excess by putting them to good use in other ways!
Have a hard-to-open jar? If it's never been opened, the air pressure inside the jar is making it harder to break the seal. If it's been in the fridge, it's possible that the lid shrunk slightly—just enough to be extremely frustrating.
Broken glass Christmas ornaments? Evergreen wreath falling apart? Before you throw away or donate Christmas decorations you no longer need, see if you can reuse or recycle them for better use year-round or for next year's holiday season.
What are you going to do with all of those Euro coins you still have from that trip to Barcelona with Grandma Margie? Instead of keeping them in a drawer and counting down the number of days until you can afford another trip, try something creative—take on this awesome miniature plane build.
If you're the kind of person who misses the bright, sunny days of summer during the colder months, Michail has the perfect addition to your home. He built this "Nuclear Explosion" Chandelier that's as bright as daylight, so you can recreate the feeling of summer, no matter what time of year it is. It puts out 99,400 lumen (a typical 60W light bulb only produces 800 lm), so it takes quite a bit of electricity to run. Michail used 7 metal-halide lamps, which are much brighter and more energy ef...
There are so many unpleasant things about flying. You have to wait in line after line, take off your shoes, belt, and jewelry, and somehow make sure your luggage stays intact. And then, once you've made it onto the plane, there are the awful movies that most airlines play—if you even get a movie.
I have an interest in using recycled materials in sculptures, particularly circuit boards and other wasted electronic and mechanical components with which I put together sprawling cities lit with fairy lights. These cityscapes can conjure an image of a parallel society built from what we throw away. Utopian or dystopian, the ‘Electri-Cities’ remain a feast for the eyes and the mind. What makes them particularly intriguing is the population of tiny model railway people—they bring a host of nev...

In Mexico there is a game called Matatena where you have to throw a ball and take some simple objects before the ball fall, who takes more win. In Bowling Matatena you are going to do the following: a Jackass' dude has to put a bowling ball in the begining of a metal rail (bigger than the drawing), then he has to run to the other side and take more matatena's little things before the bowling ball falls over his head, hand or whatever...
Get a Big metal ball (the kind of ball motocycle ride in it in circuses) put some cameras in it and some jackass dudes inside the ball (Chris pontius , Dave England, Preston Lacy, Ehren McGhehey) Next make big styrofoam bowling pins that people can stand on (dudes in pic.)find a big hill and bowl away..
Ingredients 3 tablespoons unsalted butter, cut in 1/4-inch cubes, divided
Leaving scissors wet or forgetting them outside can cause them to rust. Rusty scissors, if you can even open them, will leave brown marks on everything you attempt to cut through. Attempt is the truth—rust dulls the blades of the scissors making it virtually impossible to cut through any type of material, ranging from paper to fabric. But don't toss the scissors in the trash just yet. You can restore rusted scissors to a usable condition provided they are not completely covered and have rust ...

Take one of the guys, tie him in the center of a really big metal hula hoop by his hands and feet, give him a helmet cam, then kick him in the balls and roll him down a big hill.
What you do is you go to different places dressed as old men and when death metal or thrash metal plays, you start a mosh pit and when the music stops you go back to being old men
Whenever we make a homemade circuit, we use what are called through-hole components. Any components with long metal leads is a through-hole component. They are great for soldering to, but it's tough to fit enough through-hole resistors and capacitors into a smartphone. To get those last microns, we have surface-mount components for SMDs (surface-mount devices). These are all of those teeny, tiny things you see when you crack open your digital camera or laptop case.
I think it's fair to say that every maker yearns for a 3D printer. You can replace circuit board connectors, fix your glasses, create ski grips, and make whole machines out of printed plastic parts—even a 3D printer. But without a 3D printer on hand, you can always resort to Sugru.
If you've ever been inside of a real laboratory, you probably noticed how expensive the equipment is. You'd never be able to afford even just one of those ultra high-tech machines required to splice genes or split atoms. Even the lesser machines can be prohibitively costly, including a stir plate.
