Glass is one of the least reactive substances known to chemistry. It is the standard container material for almost all lab chemicals because it's so inert. But there are a couple of substances that have strong reactions with glass. Sodium hydroxide, aka solid drain cleaner or lye, can easily be stored in glass as a solid, but when molten, it reacts violently with glass and can actually dissolve it away! So, the next time you clog up your drains with broken glass beakers and flasks, rest assur...
Taking apart batteries is one of those things that every adult you've ever known has warned you against. Today, we break the taboo and dive into a lithium battery. Lithium has some pretty cool properties—it burns instantly in water and glows blindly bright under flame. And with just one AA battery, you can make a blinding light beam inspiring supernatural awe in all dictatorial adults who doubted you.
Law enforcement can make a lot of folks cringe. Too often do we hear on the news, and even experience in our own lives, the unjust way that an unacceptable portion of law enforcement treat the very citizens they are supposed to protect. People's rights are violate each and every day by law enforcement, simply because they are timid and uneducated with the laws of society. This dirty trickery shouldn't be played on harmless citizens under any circumstances.

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.
Dactyloscopy isn’t going anywhere. Forensic science has much relied on fingerprinting as a means of identification, largely because of the massive amount of fingerprints stored in the FBI’s biometric database (IAFIS), which houses over 150,000 million prints. And thanks to the departure of messy ink-stained fingertips, biometric analysis isn’t just for solving crimes anymore.

since zipper rides have wide seats either connect two porta johns or find a "doublewide" 2 seater crapper. if you can get away with using just one crapper, cool. mount all safety harnesses and mount the the crapper in the ride mounts. have the guys fill the crapper/s up and have someone take the ride if you dont fill them with crap at least use the blue water or chocolate pudding
sit on your ass til your legs are numb then run down all kinds of cool hills and shit dont forget safety first
China is a hot mess of traffic and is stereotyped for spawning some of the craziest drivers in the world. The traffic jams are known to be so bad, drivers have been gridlocked for 9 straight days.
Injection is an attack vector that involves breaking out of a data context and switching into a programming context through the use of special characters. These characters are significant to the interpreter being used, but not needed for the general user input being asked for.
PVC isn't something you want to send to the landfill. It's not going to do anything good for the ground when it's buried. It is also something you really, REALLY don't want to send to an incinerator. When burned, PVC releases some really nasty chemicals, including hydrochloric acid and dioxin.
This weekend, I was on a trip to Binghamton. In the midst of unpacking my toiletries at the hotel, I found that my brand new razor blade had lost its cap. How did I find that out? Well, when I pulled my hand out of the bag, I found that my right pointer finger was missing a bit of its tip and dripping blood on everything. Thankfully, Nathan G. H. Shlivovitz was with me and knew what to do, but the experience helped me to realize that everyone needs a little first aid knowledge in life. Here a...
So... This is a prank on a prank. The first prank involves everyone getting drunk one night and drugging the "victim" (say a friend of a friend, because any jackass member would know it's a prank) to the point of unconsciousness, tearing portions of their clothes and leaving them covered in fake blood in the middle of the forest surrounded by fake dead animals (humans preferably). Thick Werewolf type hair could be stuck to the blood against their skin to imply that they were turned on that fu...
After Thanksgiving, there's Black Friday, the biggest shopping day of the year, with stores offering holiday shoppers the best deals they can muster up. This year's Black Friday was practically a one-day warzone, with Target taking on most of the mayhem (see videos below).
For most people, New Year's Eve means watching the ball drop in Times Square. It means celebrating the New Year with friends and family. Countdown parties, clocks, confetti... passing out before the clock strikes midnight because you drank too much. But there's one more thing, and it's something we usually only see one other time each year— fireworks.
Move over NASA— SpaceX is taking over. Well, not really. But today, the privately funded spacecraft company broke all expectations when their Dragon capsule fell to a soft landing in the Pacific Ocean, completing an undoubtedly successful demo flight of nearly two full trips around Earth. It was the first re-entry of a commercial spacecraft ever, bringing commercial space transportation closer to reality.
If you're like me, you were always jealous of the kids with rich parents who got to ride around in their own Power Wheels cars. Now that I am tall enough to sell my body and time, I find myself attaining childhood dreams like buying my own Power Wheels car. I would not have chosen the Barbie Jeep given the choice, but 40 bucks on Craigslist is an amazing deal.
Any gun that you have in your hands, you want to assume that it's loaded and never point it at anything that you don't intend to shoot. Learn about shotgun safety in this free hunting video. Handle a shotgun safely - Part 1 of 14.
Last time we took a look at some of the creatures of the pond, including the dragonfly nymph. Today, we examine the all-grown-up dragonflies in the field you are used to seeing on summer days! Dragonflies are not dangerous, but the extra large ones can bite you something fierce if you handle them wrong.
I think it's fair to say that every maker yearns for a 3D printer. You can replace circuit board connectors, fix your glasses, create ski grips, and make whole machines out of printed plastic parts—even a 3D printer. But without a 3D printer on hand, you can always resort to Sugru.

In this series on weaponized lasers, I'll be exploring the function, operation, strength and building instructions for three basic laser weapons; CO2, Diode, and Flashlamp. These laser types are just a few of many, selected because of their simplicity and basic construction (depending on your experience).
In this article, I'll show you how to built a Wireless Transfer of Energy Transmitter. Simply put, this device will send electricity to a florescent light bulb and light it up, from up to three feet. The idea originally (at least, prominently) came from Nikola Tesla (read more about this amazing inventor here), who used his Tesla coils to transfer wireless energy to light bulbs in demonstrations (photo below). However, the circuit described in this article consists of a flyback transformer, n...

There's no doubt about it—the most elite military force in the United States is hands down, the Navy SEALs. They can operate at sea, in the air and on land, and their ability to conduct missions underwater separates them from most other military units in the world. They've fought in World War II, Vietnam, Granada, Afghanistan and Iraq, but have gained some serious hype in recent years thanks to SEAL Team Six, aka DEVGRU, aka NSWDG, who saved Captain Richard Phillips from Somali Pirates in 200...
What happens when a person who has never played a building sandbox game tries it for the first time? Reality happens. The harsh reality of human nature. You would think playing with friends in a creation game would be utopia, but in truth it's more like being stuck with people that would walk all over you if it provided a softer path.
Founded by Zach Kaplan, a "serial entrepreneur" with a B.S. in mechanical engineering, Inventables is a futuristic online hardware store based out of Chicago. The company sells innovative materials at much smaller quantities than typically available—largely to artists, inventors, developers, and researchers. If you've got a brilliant idea and cash to spare, careful, you just may go hog wild. My premature "Dear Santa" wishlist-in-progress:
With the recent death of Osama bin Laden near Islamabad, the whole world has gone crazy for Navy SEALs. Everybody wants to know what it was like for SEAL Team Six to carry out their heroic mission last weekend. Others want to know what it takes to become one.

These goggles are great for a stage prop, cosplay, Halloween, or any videos you may make! They're made to look like Sam Fisher's tridents from the game series Splinter Cell.
Super Mario Brothers! No, wait... Super Meat Boy! Yep, that's right. Meat. As in "cube" steak. As in a square piece of beef with eyes and a shitty grin, who just happens to be in love with a band-aid. I have no idea why. And no matter how shocked you are to see your dinner on your screen, it doesn't change the fact that this platform game is AWESOME!
I recently thought about playing the game of basketball but with a twist. The game is called "Tacksketball." Of course, this is an idea that I can only see #TeamJackass handling. Basically, you need to place tacks on specific areas of the area/basketball court. If their was a way to keep these tacks positioned that would be even better. However, the catch is tacks will also be placed on the basketball, so beware of passes from your team-mates. This game must be played barefoot, as salt will b...
