How To: Vent a fish

Scientific studies have shown that species with large swimbladders, especially bottom dwelling fish such as grouper and snapper, derive an immediate benefit from venting.

How To: Place a bet at horse and dog races

Watch this video tutorial to learn how to place a bet on some horse or dog races. When it comes to betting on the horses or dogs, the process is very similar. The betting shop that you are in will have all the days’ races hanging from the walls which will show times, distances and show the form and odds of the horses that are running. Decide which horse you like the look of, get a blank betting slip, write the venue and time of the race at the top, then either the horses name or just it’s num...

How To: Create a PCB Etchant That Automatically Improves After Each Use

Etching your own circuit boards is tons of fun, but etching requires strong chemicals to dissolve the copper plating on blank circuit boards. The normal ferric chloride solution works well, but can be expensive and leaves permanent stains. Luckily, we can whip up our own etchant at home with everyday chemicals! Better yet, our new etchant will turn an eerie green color rather than the dull brown of ferric chloride.

How To: Make a High-Powered Compressed Air Rocket Gun

In this article, I'll show you how to make a high-powered, long-range, air-powered rocket gun. This launcher is based on a sprinkler valve, a modified propane tank, and a few other components. Though not hard to make, this device is VERY dangerous! The rocket can seriously harm, if not kill any living thing it's shot at. Here's a video of it in action, quite an accurate shot by my friend Chris... Parts

How To: High Voltage Happiness? How to Make a Negative Ion Generator

In this article, I'll show you how to build a simplistic circuit to generate negative ions. Negative ions have been known to contribute to fresher air, happier mood, and general health benefits. However, they also look amazing in the dark (check out the photos below, purple plasma is amazing!). And if all else fails, they make a cool nightlight. If you've ever been around a Tesla coil, cathode ray tube TV or sometimes even on a trampoline, you've probably noticed that smell; the smell of "sta...

How To: Conceal a USB Flash Drive in Everyday Items

Technology in computers these days are very favorable to the semi-knowledgeable hacker. We have TOR for anonymity online, we have SSDs to protect and securely delete our data—we can even boot an OS from a thumb drive or SD card. With a little tunneling and MAC spoofing, a decent hacker can easily go undetected and even make it look like someone else did the hack job.

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: Make A High-Lighter Stun-Gun

The Stun-Gun In this article, I'll show you how to make a small, weaponized highlighter. Before I get into how to built this device, let me warn you. This device is harmful! When used, it can cause burns and/or serious muscle spasms. The voltage is potentially deadly! DO NOT attempt to build this device unless you are experienced with safety, electronics, soldering, and understand circuit schematics.

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.

News: Kaplan University–Carol Baldwin-Moody of Wilmington Trust Discusses Issues Fac

Carol Baldwin-Moody of Wilmington Trust describes the challenges that are present in her line of work as senior vice president and chief risk officer. There is a strong legal backing to every major issue in today’s society. Baldwin-Moody has come across several scenarios that aren’t covered by the dated constitutional law in effect today. In past years, a risk officer was thought to be a management concept that would be useful, but not worth the investment. Lately, a risk officer career has b...

How To: Stay Computer Virus Free

While a lot of internet threats are rather over-hyped, there are some serious things to be cautious of when going online. Probably the biggest risk to the average internet user is malicious software. Commonly knows as "malware," this term refers to any program that exists solely to do harm. This may include damaging your computer or accessing your data without you knowing. Viruses, trojans, and spyware are all forms of malware. Now, malware can seriously mess up your system, and the idea of s...

How To: String an Electric Guitar

A First Timer's Guide When some new guitarists break their first string they stash it in the closet and forget about it. Me, I put the sweaty axe back in its case and asked my parents to take me to the local music store. After a morning full of senseless racket emanating from my bedroom, my mom welcomed the drive.

News: I Love Books

I love books. I've loved books before I could even read them. I remember spending any free moments poring over the pictures, trying to pick out the words. I can recall the first triumphant moments when words began to make sense to me. I grew up in a house filled with books and with parents who read me The Hobbit, Little House in the Big Woods, The Chronicles of Narnia and so many others. I brought stacks home from the library, browsed through my dad's office shelves, used up the batteries in ...

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.

News: Zambia's Forgotten Space Program of 1962.

Back in 1962, a Zambian teacher vowed that his country would beat America as the first country to put a man on the moon, and then they would go on to Mars. Unfortunately, his dream never came to fruition. The Zambians worked hard though. His "astronauts" rolled down hills in barrels to get used to traveling through space. They practiced walking on their hands, as their leader - Edward Makuka Nkoloso - assured them that was the only way to get around on the moon. "My spacemen are ready, but we...

News: Proof of Water on Mars

Since the first time we've been to Mars, the question was 'Did there used to be life here?'. That all changed for the better when NASA told us that the Opportunity rover found signs of water- the essential part to life. NASA officials on Wednesday said the rover discovered a mineral vein of gypsum running along the rim of a crater called Endeavor. The gypsum was deposited by flowing water billions of years ago. The vein is about 20 inches long. They found it while studying a rock called Tisda...
