Many foods do not come in natural packaging that is as useful and versatile as its content. Eggs are an exception. So, the next time you buy a carton of eggs, be sure to hold onto the eggshells after you are finished cooking with them.
Today's fancy cars come with all sorts of options, from power mirrors to working seat belts. Some of us condemned to live in the reality of capitalist recession have no car, or perhaps a very modest one. But your modest car can still have some cutting edge technology wedged into the trunk and dashboard if you know what you want and where to look for parts. Today, we make a parking sensor using a sonic range finder, just like in the vehicles our owners drive!
You see before you the humble block: This single, unassuming block couldn't possibly hold anything of value, right?
The Workshop this weekend went of without a hitch! Except that it didn't happen until later at night, The workshop went exceptionally well. Lots of people came out to build in this weeks workshop and here's some nice pictures to help tell the tale!
In this article, I'll show you how to prank your friends on April Fool's Day with the very popular Google Voice, a computer to land/mobile calling feature. Basically, Google allows you to play whatever you like through the microphone port on your computer, and play it right through to your victim's phone. Whether it's Rick Astley ("Never Gonna Give You Up") or a text-to-speech application, general hilarity always follows.
The exploding ashtray prank was once fairly commonplace long before the Internet was born. Using flash cotton to create a startling explosion, this prank is certainly effective at getting a reaction. Flash cotton is a staple of many magic acts; used for its ability to create a brilliant flash of fire without causing a burn to the skin.
Glass is one of the least reactive substances known to chemistry. It is the standard container material for almost all lab chemicals because it's so inert. But there are a couple of substances that have strong reactions with glass. Sodium hydroxide, aka solid drain cleaner or lye, can easily be stored in glass as a solid, but when molten, it reacts violently with glass and can actually dissolve it away! So, the next time you clog up your drains with broken glass beakers and flasks, rest assur...
You're never too young to start building your vast swarm of robotic minions. Taking over the world requires a whole lot of robots. The sheer volume of robots needed means your first wave will have to be made of cheap materials. After they take over key resources, you can upgrade to Kevlar and titanium. But to start, let's make popsicle stick insect robots!
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.
This week, I've been working on a project that sort of takes a spin off an old-style potato gun. Using PVC pipe and the rapid combustion of hairspray, we can launch a rocket hundreds of feet into the sky. As usual for my projects, I tried to use only materials and parts that are commonly available. I even give two different forms of ignition, in case one method ends up being hard to come by. The following video will explain the project further: The launcher can be reloaded and fired repeatedl...
In this article, I'll show you how to make an awesome "Death Ray" using the large magnifying lens from an old projection TV. The lens is called a Fresnel lens; a device that employs several ridges to focus light, rather than a complete curve.
His name is Don Pettit, but I like to call him Space MacGyver. He's well known for his paper clip fixes and ingenious coffee invention in zero gravity, and we've all seen the NASA astronaut in his Saturday Morning Science videos during his first stay on the International Space Station. And now he's back on the ISS with a brand new physics-related show... Science Off the Sphere.
In a previous article, I showed how to make a powerful airsoft BB machine gun with a portable air supply using about $50 worth of PVC and air fittings. For this project, I have simplified the design to make a machine gun out of only 4 parts totaling about $15 that runs directly off of an air compressor.
Interested in taking a few snapshots of the likely auroras from the recent solar flare the Sun sent our way?
I have to admit that I am an environmentalist wacko. That may sound strange, considering my life is tied up in PVC, which is considered one of the most poisonous materials on earth... but it's true. I love this planet, and I want it to be inhabitable for as long as the sun is in this phase of its life.

Reuben Margolin builds large scale kinetic sculptures based off of mechanical waves. Some of his sculptures contain hundreds of pulleys all working in harmony with each other to create sinusoidal waves and their resulting interference patterns. He designs them all on paper and does all of the complicated trigonometric calculations by hand. Everything is mechanical; there are no electronic controllers.
This week's review roundup is a diverse lot. They really only have two things in common—their indie origins and puzzle elements. Otherwise, they come from France, Spain and the U.S., a few from unknown designers and one by the guy who inspired Minecraft.
Create Your Cardboard Masterpiece Before you can create the shader, you must create an object to test the shader out on so that you will feel comfortable with your results. I have chosen to do the traditional cardboard box for this.
If you haven't had a pile of pipe and fittings to play with before, it's hard to see what is so cool about a plain, plastic pipe. All it does in the house is carry the poop away. Really, who cares?

While using Google+, it's been apparent that there are two types of posters. There are the people who post thoughtful, serious posts about everything from tech to dealing with cancer. And then there are the meme propagators, the people who decide to rick roll others (ahem, +Bryan Crow), and constantly put up animated gifs. Sometimes they are the same people, and this is where it gets a little controversial.
What is Technology? Technology is all around us. Some technology we take for granted while other technology we allow ourselves to be amazed and baffled by. Technology is more than modern technology companies like Cisco Systems, IBM, and Google.
Beauty is a fine line between art and science for Pe Lang, a Swiss sculptor living and working in both Berlin and Zurich. The autodidact artist specializes in graceful, hand-built kinetic sculptures made of magnetic, electrical and mechanical devices, all of which are elegant and completely mesmerizing. "Positioning Systems - Falling Objects" is one of his newest contraptions, which feels like a mix of home waterfall fountains, mechanical metronomes and a busy manufacturing plant.
Ikebana, the Japanese art of flower arrangement, dates back to over 500 years ago and is still practiced as a highly respected cultural art form in modern-day Japan.
Area 51 is the most secretive military base in the United States, a base that U.S. government officials to this day still barely acknowledge because of its top secret development and testing of experimental aircraft and weapons systems. But a slew of Cold War-era documents have finally been declassified, and National Geographic has discovered a rather low-tech method the military used to hide its high-tech prototypes.
E Ink technology is nothing short of amazing. It recently contributed to the world's first bend-sensitive flexible smartphone, and now it's capable of something even cooler, not to mention astonishingly simpler—flashing digital displays on cloth.
About the 37 x 37 Homestead Expansion, Part III There’s a problem with it, and you may find it hard to complete.
These magical beans can keep your coffee hot for hours. Not blazing hot, burn your tongue on the first sip, and not disappointingly lukewarm, but coffee fit for every baby bear—just right. Genius.
Well, this is my first article on WonderHowTo, and is only going to be short because it's an extremely easy and effective method for removing a painful sunburn. This method was recommended to me by my friend's mother, who is a nurse and therefore MUST know what she's talking about. Turns out she did. I hope this helps many painful sunburns to recede or disappear.
The Lost Thing is a lovely short written by Shaun Tan and co-directed by Tan and Andrew Ruhemann (executive producer of the fantastic doc My Kid Could Paint That). Based on the award-winning children’s book of the same title (also by Tan), the piece was created over a span of eight years(!) using a mix of CGI and 2D handpainted elements. Tan, whose background is in painting, spent much of the duration "carefully building, texturing and lighting of digitial elements to create a unique aestheti...
Eric Jacqmain is one smart cookie. Borrowing from the same principles of Archimedes’ mythological death ray, the Indiana teenager used an ordinary fiberglass satellite dish and about 5,800 3/8" mirror tiles to create a solar weapon with the intensity of 5000x normal daylight. The powerful weapon can "melt steel, vaporize aluminum, boil concrete, turn dirt into lava, and obliterate any organic material in an instant."
The exile is officially over. Let the good times roll. Unequal Technologies has just signed Michael Vick as its corporate spokesman. They have applied for 50 patents that largely employ the Dupont-created Kevlar for "shock suppression". Formally speaking, this is his first product endorsement deal since his arrest in 2007.
Know the saying, "The inmates are running the asylum"? Well, if the inmates actually were running the asylum, we imagine the asylum might look something like this!
WonderHowTo favorite NurdRage once again triggers the inner mad scientist in all of us (well, all of us WonderHowTo-ians at least). Below, watch what happens when steel wool- found in every common household Brillo Pad- is lit on fire.
Turkey's been consumed, you've awakened from the food coma, and you've escaped the madness of Black Friday. Isn't it about time you tackle a new project? We've got some great new projects for you to help illuminate the darkness of winter.
Professor Wafaa Bilal of New York University plans to soon undergo a surgical procedure that would temporarily implant a camera in the back of his head. The project is being commissioned for an art exhibit at a new museum in Qatar. The Iraqi photographer will be a living, breathing cyborg for an entire year, during which the implanted camera will take still photos every minute, simultaneously feeding the images to monitors at the museum.
I saw this on the Food Network and tried it out. We loved it. It is a great way to use leftovers and with Thanksgiving coming up, I know you'll want to try it on Thanksgiving evening while watching football. I think it was Jamie Oliver who presented it although I couldn't find it on the website. It was described as a common thing done in the UK as the evening meal after a Sunday lunch. It is great with leftover turkey, dressing, and potatoes and gravy. MethodTake the left over turkey and brea...
You may think of sugar as purely a sweet ingredient meant for baking, but it can actually be a deadly explosive, according to PopSci's Gray Matter:
