News: The Rollie Hoop
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.

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.
This is the third part of my electromagnetic pulse series (see Part One and Part Two). By now, I've covered the hardware and general concept of electromagnetic pulse generators, but how exactly do they disable electronics? How can an invisible field of energy have such a catastrophic effect on computers, cell phones, and most any other electronics? I'll be answering all these questions in part three of Making Electromagnetic Weapons.
You can make homemade pizza with a minimum of tools, or you can buy the entire yuppie menagerie (and let's face it—if you're a foodie, you probably want the toys). Below is a brief rundown of the different options available. Since I'm a relative beginner to the process, I've also linked out to a few in-depth reviews.
This video tutorial shows you how to do the grit scream, or as it's popularly called the fry scream (by Melissa Cross). This scream is often used in heavy metal rock vocals. Follow the steps in this how to video and you will be able to do the Fry scream in no time.
The best chemistry experiments are those you can perform with items already laying around your house. With only some sugar, salt substitute and an instant cold pack, you can make your very own gunpowder! Being able to make homemade gunpowder without a trip to the store can be a lifesaver, no matter if it's just for testing out a Civil War-era musket, blowing up stubborn tree stumps, or preparing for battle when imperialists overrun your country.
Watching an ice cream pro build you a custom frozen treat mixed with your favorite fruit, candy, and/or toppings makes buying a cone even more exciting. But why go out for ice cream when you can create your favorite combinations in your own kitchen? While you might not have an expensive frozen slab for ice cream topping your kitchen counters, you can mimic the creamy consistency and customizable options from Cold Stone Creamery and Marble Slab any time you're craving it. Best of all, you don'...
Contrary to popular belief, sushi is not the raw fish that one gets at Japanese restaurants, but the rice that comes with it. It's hard to tell whether this popular misconception led to or came about because of the primary flavors that we think of in sushi are the fish. We often say a sushi restaurant has great fish, but almost never that it has great rice.
We've showed you how to make Butterfingers and Kit Kats, as well as custom-shaped chocolates, but have you ever thought about making your own gourmet chocolate bars?
White or light-colored dinnerware is a classic: it looks crisp, clean, and elegant. The only problem is that after you've used it for a few years, the surfaces bear a lot of grey scuff marks from forks, spoons, and knives being dragged across the surface.
If you've got a birthday party to plan for a young budding scientist coming up, a little nitrogen should do the trick. In this project, I'll show you 10 "super cool" tricks with liquid nitrogen that you could try, but probably shouldn't!
What happens when you find your ball deflated and there's no pump or needle in sight? You could always cancel your plans of kicking around the soccer ball or starting that pickup football game in the park. Better yet, you could be terribly clever and find another way to get air into the ball. From a pen to a balloon to a gas station, there are ways to inflate it.
At one point in the '90s, about fifty percent of the CDs produced worldwide had an AOL logo. About fifty percent of the CDs in my home still have that AOL promise of 500 free hours on them. Though they never got me to join their internet service, I did get a lifetime supply of coasters. Thanks to the rise of high-speed internet access and bigger and better hard drives, there's no reason for companies to snail mail any more of those obnoxious plastic discs.

If you're a Steampunk (or costumer of any variety) and you don't know what Rub 'n Buff is, this tutorial will make your life so much easier. You have no idea.
Say whatever you want, but Steampunk is primarily a maker culture. Consider that Steampunk has existed since the 1960s and yet more or less languished in obscurity until approximately 2005, which is when it made the leap to costuming. That costuming was what provided the leap to the tangible, despite the fact that Steampunk art had also existed for years.

In this article, I'll be showing you how to make a simple yet effective static electricity generator. Basically, this device allows you to carry a constant static charge on your body and discharge it on anything grounded or of opposite polarity. The electricity generated is around 8-10 kV, at a very low current. The shock is enough to startle your friends, just like a static shock from a trampoline or carpeted room. You'll need a little experience in soldering and circuit design to build the ...
In this article, I'll show you how to create a simple yet accurate demonstration of the "rising ionized gas" principle. In other words, a transformer, two metal prongs and lots of evil laughter. Remember those large "towers" in the background of Frankenstein movies with a "lightning bolt" rising upwards every few seconds? That's called a Jacob's Ladder; one of the coolest awe-inspiring demonstrations of high voltage. Here's a video of the final product: Materials and Tools
National Ignition Facility
Piezoelectric Energy In this article, I'll show you how to make a small, wallet-sized device that generates electricity from kinetic energy. The concept is simple: Piezoelectricity is the charge that is produced when certain solid materials (commonly ceramic and crystal) in response to mechanical stress. Piezoelectrics have many applications; in speakers, actuators, sensors, even fuses. For more information, click here.

No matter if you've used one or not, you've got to admit that 3D printers are pretty darn awesome, especially the self-replicating ones that extrude molten plastic and the shoebox-sized versions that use mesmerizing stereolithography to build tiny objects layer by layer. But what's even cooler? A solar-powered printer that uses the sun's energy to melt sand and make 3D objects out of glass.
Although in recent years street art has reached a high point of public appeal many of the great artists are over shadowed by the likes of banksy and shepard fairey (who are amazing artists for sure, just not the only amazing artists out there). Some of the best urban artists have never had a gallery show or exihbit, and most have only been out of their own country once or twice. But of course, thanks to the internet and movies, i )along with many others) have been lucky enough to see the work...
After stumbling across an interesting article by Hanne Blank—(apparent) hobbyist chef and widely known activist on the issues of weight, bisexuality, and sexuality—I've become even more fascinated by kitchen shortcuts. Former Microsoft CTO Nathan Myhrvold's recently released Modernist Cuisine also spurred a similar interest, particularly after reading a WSJ piece in which Myhrvold attests —by law of science, of course— that a ¼-inch-thick sheet of steel is more than adequate in place of an ex...
One of the creepiest musical instruments ever is undoubtedly the theremin, a device originating from the early 20s that emits eerie sounds with a just a wave of the hand. If you've seen the original movie The Day the Earth Stood Still, you know what I mean—freakishly creepy. Playing the theremin can be off-putting for some, since it's a relatively pricy gizmo, but a new geek gadget called the EaTheremin aims to make all of us professional, dinnertime theremists.
'Tis the season for Christmas tree decorations and everybody's favorite board game— SCRABBLE! Okay, that was too ebullient on my part.

This is unfortunately, though, because you can outperform your competitors by following up with leads and encouraging them to choose your business.
You will need 2 packs of kanekalon hair extensions, gel, for a firmer hold. You will also need clips to get the hair out of the way and a comb to make straight lines. A lighter is also used, to seal the ends. You first want to separate the air into sections. Put a little bit of gel at the root of the strands. You get the strand of extensions between your thumb and index finger, with the strand in the middle. Then you braid the extensions with the natural hair and twist so the two of them bond...
