Taking apart batteries is one of those things that every adult you've ever known has warned you against. Today, we break the taboo and dive into a lithium battery. Lithium has some pretty cool properties—it burns instantly in water and glows blindly bright under flame. And with just one AA battery, you can make a blinding light beam inspiring supernatural awe in all dictatorial adults who doubted you.
The agents of empire do not always arrive with warning. When you are besieged, surrounded, and infiltrated, imagination is often your best weapon against the oppressors. If all you have at hand is some duct tape and a disposable camera, fear not, you have the makings of a powerful taser!
Jet engines combine oxygen from the surrounding air with on-board fuel to burn at very high temperatures and create thrust in the direction of the flame. Rockets, which we will learn about in a later post, are similar but carry oxygen internally and can therefore function in space!
In this article, I'll be covering Triggers and Coils, part two of the series (see part one here). Generally, a simple EMP generator consists of four components; a capacitor, a transformer, a trigger and a coil of copper wire. The transformer component can be varied, but the coil is very important, and must be precisely tuned.
Hideo Kojima is one of the biggest names in Japanese game design. He's the man behind every Metal Gear game, each of which has been beautiful but divisive. He's an auteur, a rarity in AAA game design, managing business, design, and programming for Kojima Productions. Last week he made a rare public appearance at the USC School of Cinematic Arts, which contains the school's video game programs, and gave a 90-minute talk about his career, influences, and the specifics of his new Fox game design...
Jim Lahey's no-knead pizza dough is more time consuming than Jamie Oliver's "cheat's pizza", but it's quicker and simpler than the more traditional dough recipes. The rise time is only two hours, and the kneading is minimal. I still prefer Jamie's pizza, but I sense this is because I haven't quite mastered Lahey's recipe yet.

Many things cause a bike tire to deflate. Glass, sharp rocks, tacks, and nails can pierce the tire and puncture the tube within. A tube can be pinched between the rim and tire causing the tube to split when inflated. If a tire has a hole in it, the tube, which is filled with air pressure, will bulge out of the opening and pop. As well, the valve holding the air pressure in the tube can be damaged or faulty.
I have just finished making this 20 minute detailed video that shows you exactly how to build two different sized underwater viewers. One is 12" x 3" and the other is 24" x 4", but you can make them any size you like. These are ideal for gold prospecting, fishing (seeing what the fish are up to) and just for fun—kids love them. IMPORTANT NOTE:
First, I would like to explain that among my family members, I am considered somewhat of an oddball. Mostly because of some of the mods that I have performed on a few of my woodworking tools. After I show you what I did to my drill press, you may be inclined to agree. When I first hatch an idea in my little pea brain, the first thing I take into consideration is whether or not this mod is irreversible and will destroy my tool. In the case of my drill press, I determined that it was safe to pr...

We've all heard of the power that red wine holds. It can help lower risks of heart disease, boost your brain power, and can even recharge your car battery. But last year, a group of Japanese physicists made headlines when they announced that they could induce superconductivity by soaking metals in red wine. But why red wine?
The biggest struggle with flashing DVD drives on Xbox 360s has been the price tag of the probe to extract keys on some drives. The probe and kit is required to extract the DVD key, which is needed to perform a drive repair, flash, or backup of any kind. Who wants to pay big bucks for the "pro" kit and then get added to a huge waiting list behind a million other people looking to buy the same product? We can hack the same thing together at home!
I love this project. It involves fire, projectiles, electricity, and is easy to put together from commonly available parts. This mini cannon fires airsoft pellets, is fueled by alcohol, and is made almost entirely from parts found in a standard BBQ lighter. The total cost is under $5. About half of the BBQ lighters out there have a divide in the gas reservoir which makes them not work for this project. In case you have trouble finding a suitable lighter, the exact one I use in this video is a...
There are tons of mobile apps out there for the gaming logophile, but there's a new word building game taking over iPhones and iPads, and it not only wants you to have fun, it wants you to fight back in the "war against words". It's the Word Examination Laboratory for Dynamic Extraction and Reassessment. But you can just call it W.E.L.D.E.R. Since its release earlier this month, W.E.L.D.E.R. has developed quite a following with its addicting mesh of Bejeweled, Boggle and Scrabble gameplay. It...

Japan has a tendency to produce things that boggle the Western mind. Its citizens are already responsible for without a question the weirdest music video in the history of the medium. With that said, here is a video reenactment of several Pokemon (Pocket Monster in Japan) games released by Japanese performance art troupe Kusarine Project: Kusarine Project and their amazing YouTube channel first became known through the Japanese video sharing site/meme originator NicoNicoDouba. Their white mas...
Get ready to rack your brains, because it's time for another Scrabble Challenge! I may have gone a little overboard on last week's challenge (there was over 25 anagrams to solve), so I'm slimming things down this week. This time, there's only one puzzle.
The use of unmanned aerial vehicles (UAVs) has been widely used by the military for surveillance and reconnaissance missions—even armed combat. But there are other beneficial applications of an unmanned aircraft, such as search and rescue operations, scientific exploration, locating mineral deposits, transporting goods and even filming bikini models. But drone development can be pretty pricey, unless you just happen to have a 3D printer...
Giveaway Tuesdays has officially ended! But don't sweat it, WonderHowTo has another World that's taken its place. Every Tuesday, Phone Snap! invites you to show off your cell phone photography skills.
In just a few days, the biggest expo in the video game industry will unleash the newest games and hardware from all of the major companies. Nintendo is set to unveil its Wii-replacing Project Café and Konami will showcase its upcoming lineup, including new Silent Hill and Metal Gear Solid games. But what will Sony be presenting at E3 in Los Angeles this year?
Can't remember when to water the plants? Wish they could just tell you when they need watering—just call you on the phone or something? Or maybe text you, "Help I'm desiccating!" Telecommunications researcher Kate Harman has come up with the device of an absent-minded plant owner's dreams—Botanicalls. It hooks up to your plant and sends you a short text message when the plant is too dry. Each kit costs $99 and includes metal sensors connected to a microcontroller. Insert the sensors into the ...
How about a laser? One that is strong enough to nudge debris out of earth orbit. That's what NASA contractor James Mason wants to do, and his lab simulations suggest that the idea is possible. Mason wants to use a 5kW ground-based laser and a ground-based 1.5 meter telescope to spot potentially hazardous space waste and shove it off, by about 200 meters per day of lasering. It's kind-of like air traffic control for near earth orbit.
In the far away land of Japan, gold is out, glow-in-the-dark is in. LED "grills" were recently conceived of by two Japanese designers/hackers for a winter advertising event at clothing store Laforet Harajuku. The LED teeth attachments quickly became a hot item. Foreseeably, one of the two designers demonstrating the teeth in the video above is the familiar Daito Manabe (our favorite "self-electrocuting" mad hacker). Manabe's partner, Motoi Ishibashi, came up with the idea when "he saw a video...
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:
Have the victim park their car in a normal parking spot. While they are in the place they parked at have another car (the prankster) drive up and swipe the back of the victim's car, leaving huge dents in both cars. Have the prankster wait, hidden, outside for the victim to come out leaving his car parked behind the victims. When the victim comes out he will see his car smashed and the pranksters car sitting behind also smashed up. The prankster will come running out of "the building" and star...
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.
With an impressive series of viral music videos to their name, it is no surprise that the latest video from indie rockers OK Go is another hit. The video is directed by James Frost, in collaboration with Syyn Labs, a collective of engineers that work on elaborate art projects. A huge Rube Goldberg machine was built in a warehouse, for a one-take video for the song This Too Shall Pass.
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.
