Did you know that the average cost to make a penny is about 2.4 cents?!? That's why the Obama administration asked Congress earlier this year for permission to change the metals in the penny, hoping to get the cost back down where it makes sense.
Ever wondered what the inside of a burning rocket looks like? Well, thanks to Valve engineer Ben Krasnow, now we know. He built a homemade hybrid rocket engine that's see-through so you can actually watch how it works. And even though it's probably a really bad idea to try this at home, he made a video so you can build one, too. Just don't say I didn't warn you.
Remember going to the doctor when you were a kid? If the word 'traumatizing' comes to mind, you'll love the RoboDoc by MarkusB, a robotic doctor that makes checkups a little less scary (and a lot more fun) for kids. It all started when Markus took his 14-month-old daughter for a checkup. The finger clip that the doctor used to check her pulse terrified her, so Markus decided to build a heartbeat monitor just for kids that's much more likely to make them laugh than cry.
We've all played with bubbles as kids, but I think most would agree that they're not exactly the most functional of objects. An international team of researchers made up of Yoichi Ochiai, Alexis Oyama and Keisuke Toyoshima wants to change that. They've figured out how to project both 2D and 3D images onto a micro membrane (soap bubble) using ultrasonic sound waves and a standard projector. The bubble is made of a solution of sugar, glycerin, soap, surfactant, water and milk. The glycerin and ...
Here's how to build a sexy looking water-fuel generator that will convert your tap water into an extremely powerful, clean burning gas!
With the upcycling revolution, folks are turning their otherwise useless junk into something functional for the home. Practically anything that you would normally toss or recycle can be reused for a bigger and better purpose. Your milk jugs, chopsticks, toilet paper cardboard, glass jars, and even your old junk computer keyboards can be upcycled into something totally useful around (or away from) the home.
Want to liven up your game of beer pong? You could always add more cups or play with paddles, or you could make your own custom table with 500 LED lights that flash in sync with your favorite tunes like Redditor did.
Chopsticks are very easily reusable, yet they always get thrown away. You use them when you get Chinese takeout, then toss them out without even a backwards glance.
Stop me if you've heard this one before. A man walks into a bicycle shop, hears about a canoe made of cardboard and is inspired to make an awesome, fully-functional cardboard bicycle. Sound far-fetched? Wait until you hear how his guy actually did it. Israeli entrepreneur Izhar Gafni says that the idea for his method came from Japanese origami. Folding the cardboard increases its strength by 2-3 times, making the material much more durable. Essentially, he made the basic shape for each part w...
If you're familiar with games like Half-Life 2, Left 4 Dead, Portal, and Team Fortress 2, then you've probably seen some of the cool animated movies that Valve has made for them using their Source Filmmaker moviemaking software. It's a tool built to make animated films inside their Source game engine. It's even been licensed to make the upcoming animated film Deep.
Hey guys! Just made a tutorial on one of the best TNT cannons I've ever made. It was in a video, but I've improved it to shoot soooooo much farther. Hope you guys like it!
This is a shutter release that also a bulb mode switch. I made it a while back and also made a how to on it, which you can check out here.
Hey, 10bitable and me(ally132) made rock paper scissors in minecraft, so 10bit made a quick tutorial. We will make a better version but this should do for now. Also check out my channel.

Industrial espionage, social engineering and no-tech hacking are all very real and there are simple precautions that you can take to protect yourself, which this article will discuss. Whether you are a high-profile businessman or a housewife (or husband), keeping information you want to keep private, private, should be important to you.
In my tutorials, I often talk about the things you can do to improve your builds in Minecraft. However, this time I'm covering 5 things you should never do in your builds. These tips will improve your projects because they help you avoid making mistakes that can leave your construction boring and uninteresting. The only exception would be in Survival mode, especially when you're just starting out and do not have many resources. All of these tips are fine to use if they are part of the style o...
This week, researchers from Symantec shared information on the recent discovery of a new variant of the Zeus Trojan. This new variant of the popular and ever-changing banking Trojan makes use of P2P communication exclusively, making the botnet have no single point of failure and ensuring it can be kept alive and gathering data that the cybercriminal can profit from. In other words, this new variant requires no central Command-and-Control server to control the bots.
Amazingly, a lot of people I know haven't even heard of SOPA or PIPA. Now, every English-reading person with an internet connection will finally have those two four-letter acronyms emblazoned in their minds. For the entire day today, Wikipedia's English-language site will be in total blackout in protest against the proposed legislation in the United States. And that's not all. MoveOn, Reddit, BoingBoing, Mozilla, WordPress, TwitPic and other popular websites are down today in protest.
Below, my construction of a Platonic Solid made from playing cards. To make your own, templates can be found at George Hart's site; there are also full step-by-step instructions here.
Posted below is an interesting video on the effects of low frequency square waveforms on cornstarch. To make, simply mix cornstarch and water, then place on a large speaker hooked up to an amplifier and a signal generator (generating around 20-30 hertz). An old stereo works great, as long as it has an aux-in. There is lots of free signal generating software at arms length, like this one. I found adding a little olive oil into the cornstarch mix makes it easier to handle, and contributes to th...
After I made a blog and sent it to my friends about how I made Gingerbreadman Map fractal holiday cookies, one of them linked me back to the Sierpinski Carpet cookies, which I loved! So, I thought I'd share my how-to with everyone as well!
When Cerek mentioned astronomy-inspired artwork in his Astronomy World introduction post, I immediately thought of Russell Crotty. Crotty is a California artist who creates beautiful sculptures and drawings inspired by astronomy, landscape, and surfing.
Imatfaal's awesome post on Escher's tessellations on Polyhedra reminded me of some ornaments I made this summer. I made some of Escher's square tessellations onto cubes and then reprojected them onto spheres. I actually used a 60 sided Deltoidal hexecontahedron since that net is fairly easy to fold and looks pretty round.
This is my favorite paper toys I made earlier this year just for fun. Enjoy) Made with Iphone 4, Camera+ app and PictureShow.
Gem from Tron Legacy wears a lot of makeup, making her character a perfect candidate for a cool Halloween costume. If you want to look like Gem, take a look at this Halloween costume guide to learn how to apply makeup that makes you look like her.
This is an in-depth tutorial page that teaches flute making theory and shows how to make several different (they have freakin' tables of information and dimensions) flutes from ordinary PVC pipe.
The "slide-together" paper construction method is a fun and satisfying way to build 3D geometric objects. It only requires paper, scissors or an exacto knife, and some patience.
Overhead camera boom made with PVC pipe, from Dino at Hack a Week:
After seeing your tutorial on making PVC sculptures, I remembered Theo Jansen. His sculptures are so beautiful. Are they made with PVC? It's some kind of plastic tubing...
This has a great tutorial for making the generator and a few fun things you can do with it.
Here is my entry for this weeks giveaway Tuesdays. It is my home made potato cannon rev2. The next step is to spray paint it so the purple isn't showing and to fix the valve. It was originally all 1inch PVC pipe but i cut the chamber and barrel off and made it 2inch PVC for bigger objects and more air power
This is not an entry, obviously, but we wanted to try to make the mascot too (Kari and I). A few days ago the server we played on was down for two days so we were playing around making the mascot in a temporary world.

Do you love video games? Would you devote your free time to creating your own game—one superior to the games you already have? Or at least one that has more Neil Patrick Harris jokes?
Just how private is your Facebook profile? To some extent, that's up to you. Many Facebook users share and poke their days away, never knowing about the plethora of custom privacy settings that lie just a click away. Facebook's privacy menus can look a little complicated to the newcomer, so today I'm going to give you a basic look at what lies under the hood.
From Fox News, the Marquis Los Cabos resort in Baja California Sur, Mexico is now offering a $1,000 Popsicle made from 24 ct. gold flakes and Tequilas Premium Clase Azul Ultra—a premium liquor that goes for $1,500 a bottle. You can enjoy the gold-laced ice pop as you're lounging by the pool.
So very pointless, yet unquestionably spectacular. The best kind of "art" performs no other function than to delight the viewer, and Japanese YouTube user Denha's complex marble machines do just that. But are marble machines art? You can call them that—or toys, scientific contraptions, engineering feats—but however you choose to label them, the best marble machines are complicated, skillfully crafted, and driven by the principles of potential energy, kinetic energy and gravity.
This is my first video of many that I will be making. I will be making videos for Call of Duty Black Ops as well as Battlefield 3 once that game comes out. If you are interested, then make sure to join my world = )
Hey, check out this awesome trailer made, not by Notch, but by a fan!
