How To: Stop Bike Thieves Dead in Their Tracks! Make a Magnetically Controlled Bike Alarm

Bikes are a great form of transportation. They use human energy more efficiently than any other machine. You can keep it in your closet or hallway. You can even take it on the train in a pinch. However, this portability is also the bike's biggest draw back. If you own a bike in the city, chances are it will be stolen. Locks barely deter thieves armed with bolt cutters and crowbars. Throw the bike thieves for a loop and make a tilt-sensitive alarm. It will hopefully startle your bike's assaila...

How To: How This Newly Discovered Amazonian Bacteria Is the Secret Key to Biodegrading Plastic

Since the rise of private property and industrial production, modern capitalism has been on a undeniable crash course with Mother Nature. It's no so much that we'll end up murdering the entire planet, but just that the planet will quietly smother us with a pillow of famine, heat, cold and hurricanes. We over-farm land and replace the nutrients in the soil with oil. To package our oil-based produce, we wrap them in synthetic oil-based plastics, soon to be discarded in a trash heap or ocean.

DIY Scientists Beware: When NOT to Use Household Chemicals for Your Projects

The only thing better than successfully pulling off a new experiment is doing it with household materials. You get to laugh in conceit as professional scientists everywhere spend all their grant money on the same project you just accomplished with some under-the-sink chemicals! However, there are times when DIY gets dangerous. Some household chemicals are not pure enough to use and some are just pure dangerous. Let's take a look at two problems I have encountered in the course of mad sciencing.

Fire Texting: How to Write Secret Messages with Fire

Writing secret notes with lemon juice was one of my favorite pastimes as a child. All it took was a small flame to lightly scorch the paper and reveal the hidden message. Now that I'm tall and pay bills, lemon ink just isn't exciting enough anymore. Luckily, we can use another kind of invisible ink to write in fire! By using the saltpeter, we can whip up invisible fire ink in no time.

Preparing Builds, Part 1: Terraforming

Throughout this integral guide, I'm going to aid you along the path to bigger and better builds. Often times, people just jump in and build, but we mustn't hurry things if we want our builds to be all the more satisfying when they are finished. Building the actual builings should be the easy (and the most simple step in any great build), but we have to start with what's underneath your pixelated feet.

How To: Make a Prank Stun-Baton

In this article, I'll show you how to make a portable prank stun-baton. Powered by static electricity, simply charge up the baton, and discharge it for a static surprise. The concept behind this device ties in with Leyden jars, and their tendencies to retain static electricity.

How To: Join the Fight Against SOPA and PIPA

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.

How To: Make Icosahedral Planet Ornaments

In honor of the new Astronomy World, I thought we should look at a few planetary icosahedrons. The icosahedron is the most round of the Platonic solids with twenty faces, thus has the smallest dihedral angles. This allows it to unfold into a flat map with a reasonably acceptable amount of distortion. In fact, Buckminster Fuller tried to popularize the polyhedral globe/map concept with his Dymaxion Map.

How To: Make Sierpinski Carpet Cookies

Since it is now the holiday season, I thought we could spend this weekend making some baked goods that have mathematical patterns on them. In this post, we'll look at making cookies that have a fractal pattern based off of a modification of the pixel cookie technique.

News: Creating Social Structures in Minecraft

Minecraft is the most basic and barren open sandbox building game. There are a limited number of materials and recipes to craft. But with these few building blocks, people have been able to creatively build some amazing structures and cities. There is a physical limitation, but the beauty of the game is turning that limitation into a strength.
