In this experiment, we're going to get Mn2O3 (manganese(III) oxide) from MnO2 (manganese(IV) dioxide). Mn2O3 forms brightly red or a dark red colored crystal. It is used in Li-ion batteries, since (in a form of a crystal) it conducts electricity (much like MnO2).
Pie and pi lovers rejoice: whether you like eating pies or calculating their area, 3/14 is your day. March 14 is a holiday for both bakers and math nerds: Pi Day, where the day and month correspond to the first three digits of the most famous mathematical constant.

Imagine if Apple sold customized, jailbroken iPhones at their retail stores. Do you know how freaking awesome that would be? Knowing Apple and their extremely tight-assed regime, it's more likely that Tony Romo will actually win a Super Bowl (Cowboys burn).
Getting sunburned sucks, and according to the Environmental Working Group's 2012 survey of over 800 sunscreen brands, 75% of them contained potentially harmful ingredients linked to hormone disruption and even cell damage that may lead you to skin cancer. Yikes.
A ziplock freezer bag full of raw egg yolk and chopped up vegetables in a pot of boiling water may not sound like the most appetizing way to make an omelet, but this technique definitely works when you're camping and don't have a stove.
No matter how good you are at baking, we've all had a cookie mishap (or disaster) or two. Sometimes you forget about them and they burn, other times you open the oven to find your sweet treats have melted into one huge, disappointing blob of a cookie. And occasionally, you just picked a bad recipe (although no one ever believes you when this is the case).

Light-weight, tiny, and easily doable, Mark Jurey's penny stove instructional demonstrates how to make a sleekly simple (and cheap) camping stove.
Impossible, right? Ahh, well science says fire and ice can and do coexist.
This one starts out pretty tame with the water prank. But rest assured, the second round pen prank satisfies. We very much appreciate the 'safety' of adding water to the pen body in case the flame gets out of control. Nobody laughs at third degree burns.
Taking good care of our colon should be one of our capital concerns. Do you know that like the air we breathe, the colon additionally becomes polluted with toxins? Toxin accretion will appear for as continued as you continuously eat.

File recovery on Linux is a bit different than Windows. It requires different software than the Windows counterparts because every OS has their own file system. Windows uses NTFS, or FAT file systems, while on the other hand, Linux uses ext-based file systems. I personally use ext4 file system because it's the latest and greatest ext-journaling system and supports a large level of directory recursion and file sizes, but most installations still use ext2 or ext3. When files are deleted from a ...
(Difficulty Level: from Newby to Expert) Digital cameras can produce freaky sharp images—it’s one thing that sets them apart from film cameras. A DSLR doesn’t have grain, it has noise—and that sounds a lot less charming for a reason. If you shoot at a low ISO, high f-stop and fast shutter speed, you can wind up with a super sharp image that might look great even on a billboard. But sometimes, sharp isn’t everything.
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.
Your roommate swears by 'hair of the dog' or chugging raw eggs and tomato juice, but do these hangover cures actually work? What do the scientists say?
Have you been thinking about joining a local Belly Dance Class? Many people are curious about Belly Dance but are unsure of what to expect in a class, or may be worried about not being the "right" body type, weight, or age.
So I totally blanked on taking pictures of my last project so I could share it, mea culpa. Instead, I figured I'd write a post on all the different ways you can sew a pouch.
I remember once listening to a Christian comedian making fun of the way some Christians pride themselves on all the "evil" things they don't do.
I think Preston should race down a steep hill on a big wheel made for a little kid! He can only wear underware and he has to be sitting! The wheels will rub against his skin causing a really bad burn! At the end of the hill he will crash into a big pit of shit!!!!
Japan's Shoichi Uchiyama is a hardcore advocate of insect cuisine. His selling point? A heavenly nutty flavor, the delicious texture of shellfish, AND high in nutritional value.
You've had a massive hard disk failure.. ...in your PC or laptop and like a large number of people who think it will never happen to them...you did not have a backup of those 2000+ family pictures, those hundred of important Word documents, those family videos that you downloaded from the camera then erased from the cameras disk...the inevitable "I'm Screwed!'
Alice Waters and The Green Kitchen So what, yes I admit it I am drawn to all things Alice Waters. So sautee me. A new discovery was made today while walking through my local bookstore. I found a sweet looking cookbook with Alice on the cover. Naturally I stopped. The item of my interest was a sort of "how to" cookbook called In The Green Kitchen
Tired of the same old noodles? Well, bring a little vegetarian flair to noodles by using fresh cut carrots. But this is only if you really love carrots. You have to. Because they're carrot noodles. Give it a try and see the whole recipe for carrot noodles in orange-ginger glaze.

Intro to Camotes Older Filipinos love eating camotes, also known as sweet potato fries, for breakfast. Aside from filling your stomach completely, it also has fewer carbs than regular white rice.
Ingredients 4-5 cloves of garlic, finely chopped
I finally got around to trying out another one of Will's mad science experiments and found out that this one was actually more satisfying (and less frustrating) than my slightly uncooperative jar jet. There's something very pleasing about making potassium nitrate at home in the kitchen and then watching the transformation from semitransparent liquid to spiky, frozen crystals. That was the best part for me, second only to igniting it with its sugar companion.
It turns out that the popularity of soft circuit electronics has leaked out of the interwebs and into the hands of the U.S. military. Soft circuit electronics allow you to literally sew electronics circuits into fabric using flexible conductive thread instead of wire. Soft circuits can be used for all sorts of fun projects, like the TV-B-Gone Hoodie and the Heartbeat Headband.
The most recent viral video on YouTube is just that. A viral video. After seeing all the hype and 'support' that the 'movement' is getting, I want to tell you that this is a misleading video and somewhat of a propaganda campaign. These are strong accusations against such a 'humanitarian' cause, but I'm here to show you why.
With the mass arrests of 25 anons in Europe and South America, and the rumors of an FBI sweep on the east coast of America floating around, times look dicey for hackers. Over the past few days, a lot of questions have been posed to me about removing sensitive data from hard drives. Ideas seem to range from magnets to microwaves and a lot of things in-between. So, I'd like to explain a little bit about data forensics, how it works, and the steps you can take to be safe.
I'm not sure exactly when it happened, but it's awesome that you can now download music from the iTunes Store that's free of DRM (digital rights management) limitations. That was always my biggest problem with buying music from iTunes. Paying a buck for a song that I can only play on Apple devices? Really? That's what finally led me away to other legal music downloading services like eMusic and Amazon.
Introduction Ever wished those flabs of fat would just disappear? Ever envied those models with skinny flat stomachs that no matter how hard you try, you just can't get? You've come to the right place. Even those of you who can't resist leaving a single morsel left on your plates will be forced into a skinnier, healthier shape.
Last week, I did a short tutorial on three main types of flooring for your Minecraft builds. This week, I will be focusing on just one of those—inset floors. This was the first of the three types I briefly covered, and the example I used was an inset fireplace. Here, I will be going over 5 types of inset floors. I did not light the fireplaces, because the building I was using kept burning down.
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 ...
