Kid-Tested: Projectile Weapons for Indoor Warfare

Posted by shaun on Saturday, 30 April, 2011

Zing Toys sent us several boxes of its newest office weapons, so we asked the children of various Wired employees to test them.

Cool Guns

Posted by othertech on Tuesday, 5 January, 2010

A gun is a firing projectile that is actually a weapon. There are many kinds of guns such as firearms or small guns like pistols or rifles. The generic term ,,gun’’ was used to name artillery tubes and sea-based naval cannon. This weapon has a tubular barrel and a hollow. The directing of the projectile is made by the tubular barrel. The term ,,gun’ is also referring to grease gun , glue gun, staple gun, nail gun. Guns are divided by the means of firing, by the type of barrel, the caliber and the purpose of the weapon. Rifled is a type of barrel which has angles in it and spiraled grooves. You can identify guns variations by the projectile size and barrel diameter. The bullet has an explosive shell. Explosive liquid, explosive solid or even air may be the propellant. The word ,,cannon’’ replaces the ford ,,gun’’ and it is a word that come from the French language. Back in time, firing a gun was seen as black art because of the sulfur smell and flash.

In military use, guns were called the weapons that fired directly. The word cannon doesn’t refer to the weapon system but to the actual gun tube and the name gunner is used for members that fire the gun. As the name implies, autocannons are automatic guns that are mounted on a vehicle and fire shells. Machine guns are almost the same .Gun type fission weapon is a nuclear weapon while captive bolt gun is used to slaughter animals. For hunting, shotguns are normally used.

When you handle firearms, you have to know the recommendations and rules that can be applied, in order the risks to be minimized or eliminated. Risks such as injury or unintentional death can be caused by handling the firearms not in an improper way. Firearms are dangerous and they have to be handled with care. You should take the finger off the trigger and point the weapon at the ground. The best way to be safe is to think that your gun is always loaded, in this way you will be more careful with it.

Here are some other ways in which guns can be detrimental to bystanders or handlers: the noise is one of them. I’ sure you have all seen in movies when actors are learning how to shoot, they have headsets. Tinnitus is a permanent or temporary hearing damage so in order to prevent this you have to use hearing protection.

A gun emits powder and gases that can do harm. The toxic effects are now diminished. The risk of exposure is also diminished if you wash your hand properly after you use a gun , clean and ventilate the space. Although are made to function well, malfunction can also happen.: hang-fires -delayed discharge., duds- failures to discharge and squibs- insufficient discharge. ,,Jam’’ refers to mechanical malfunctions and include eject or extract a cartridge, failure to fully cycle after firing.

People always made a connections between guns and violence. But guns are not always bad. You can defend yourself with a gun if you feel you are in danger. This is a legal act but if you use guns to harm someone it’s illegal.

Below you can find some cool guns and a short description for each of them.

-Pistole Parabellum 1908 also called Luger. In both War Wars this gun was used by Germans. After that, they were collected as trophies.

-Walther PR and PPK is a semi-automatic double action gun and the first one was released in 1929.

-Colt M1911 has a successful design used by United States Army. Now you can still see it in video games and movies.

-Glock Pistol was created in 1982 and it is a semi-automatic gun. It is the gun that became ideal for FBI, police.

- Colt Python is one of the most popular revolver.

-CZ75 was created by Czech and made of high quality steel.

-you can still find Mause C96 which is made even today.

Here are some benefits of cool guns: when someone kills another one just to save the victims, several lives are spared.These aspects demonstrates that there are more aggravated assault, rapes and less murders. Children are more likely to die from accidents, burn or drowning than from gun accidents.

The person who will be held responsible is, of course, the one who was behind the trigger. People should take responsibility for their actions so if they want to have a gun they also have to make a liability insurance, they will cover the loses in case they harm someone with the gun.

The bad part is that 5 percent of home homicide are committed with the gun that was held in the house. Even know we can’t still decide whether is a good or bad thing to own a gun. Although it is appealing to me the idea of a world without guns, the number of people who want guns is increasing. We can’t decide and in fact we don’t have to decide if it’s a bad or a good think to have a gun. We just have to think under what conditions someone could own a gun. The question is ,,do we really have the right to own guns?’’ Many think that we have not only the moral right but also the Constitutional one in order to own a gun. If they are correct that is left for us to judge. Meanwhile, we have to live with guns around us, and that’s a fact.

Dremel User Allegedly Proves CD-ROM Speed Limit

Posted by everyjoe on Monday, 12 October, 2009

My only experience with a fast-spinning CD threatening to cause damage was when I repeatedly pushed the eject button of a (CD-only, this was at least 7 years ago) optical drive that seemed unwilling to spit out my media. Then suddenly for some reason, the tray extended, and before I knew it, the CD—still spinning at top speed—actually flew upwards! I swear this anecdote is true!

Courtesy PowerLabs.org

In any case, a recent experiment theorizes that spinning a CD way faster than 56 times a second (or 56x, I assume) carries its own set of dangers. According to the experimenter, going above that speed magnifies the tiniest imperfection on a CD, potentially causing enough wobbling to damage the rotating mechanism. So of course he decided to test a CD with a Dremel, running it at over 35000 RPM. At those speeds, the edge of CD moves at nearly 800 kilometers per hour! (Or 792 kph, to be exact).

So what happened when a Dremel took a CD for a spin? Well, “the CD hummed and whined in a very menacing manner”. Scary, but it still took “quick jerk at the tool” to make the CD a projectile. Experimenting dude recounts what came next:

…the CD slid out of the holder and contacted the carpet whilst spinning at ungodly speeds. It peeled out a bit in front of me and proceeded to make its way to the door at a very high speed. On contacting the closed door, the CD did a most unexpected thing: it first bounced back a few inches, and then, when it hit the door again, it jumped straight up the door and struck the ceiling, exploding into thousands of fragments which rained down on the entire room. This first experiment was unfortunately not videoed, but it served to get everyone in the room to put glasses on and cower away behind pieces of furniture, whilst people in the hall corridor quickly made their way to my door to ask what was going on.

In other words, spin a CD-ROM really really quickly, launch into a hard surface, and you’ll get a pretty wicked disc that potentially creates deadly shrapnel. The experiment page (link below) contains multiple videos for download, if only to satisfy your visual curiosity and help you resist the temptation to try this at home.
