A difficult concept for many students to understand is the energy involved in breaking and forming bonds. A hydrate is a substance that has water bonded to it. In order to dehydrate you must add energy (endothermic) to break the bond to water. When hydrating you are forming a bond to water and will release energy (exothermic). This visual demonstration reinforces the concept.
A flashlight is one of those things you rarely need, but hardly ever have when you do. The normal-sized ones are unwieldy to carry around, and the small ones that you keep in a purse or car are easy to lose.
If you're the kind of person who misses the bright, sunny days of summer during the colder months, Michail has the perfect addition to your home. He built this "Nuclear Explosion" Chandelier that's as bright as daylight, so you can recreate the feeling of summer, no matter what time of year it is. It puts out 99,400 lumen (a typical 60W light bulb only produces 800 lm), so it takes quite a bit of electricity to run. Michail used 7 metal-halide lamps, which are much brighter and more energy ef...
A smartphone is pretty much useless with a dead battery. When you're out and about, it can be hard to find a place to plug in (if you remembered your charger, that is). But this DIY solar panel backpack made by electrical engineer Theodore Protasiewicz will help you use the scorching sun to your advantage and make sure that your gadgets are always ready to go. Theodore started with just a normal backpack, some solar panels, 18 gauge wire, and a USB port and hacked it into a traveling solar ch...

Michael Faraday was an English chemist and physicist - a bona fide electromagnetism and electrochemistry genius. Without him, men couldn't walk on live electrical wires. Wait, what?
Hotly contested video. The question remains, is the science behind the potato fire bonafide or bogus? We have yet to try it over here at WonderHowTo, and the comments thus far haven't indicated a solid verdict. Try it out and let us know! Is this a hoax? Or can you truly start a fire with a potato, salt and toothpaste?
Old Hard Drive + MP3 player = Music This equation just doesn't make sense. If you're an iPod addict, the HD element is redundant! Well, take a second look at what constitutes a speaker and what a hard drive is made of. They are more alike than you'd think.
PirateBox is a great way to communicate with others nearby when cellular and Wi-Fi networks aren't available. With it, you can anonymously share any kind of media or document and even talk to one another by voice — without being online. However, it needs a Raspberry Pi, which is more expensive than ESP32 boards, and if you only need a text-based chat, there's a much simpler option.
Before you figure out how to strip the paint on your car to bare metal, you should should first ask the question, should I strip all of the paint off. Depending on the type of job you're doing, it may actually be better not to strip all of the paint off.
Welcome back, my rookie hackers! As hackers, we are often faced with the hurdle of cryptography and encryption. In some cases, we use it to hide our actions and messages. Many applications and protocols use encryption to maintain confidentiality and integrity of data. To be able to crack passwords and encrypted protocols such as SSL and wireless, you need to at least be familiar with the concepts and terminology of cryptography and encryption.
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.
Cryptography is a quintessential part of computer security in the modern world. Whenever you buy something on eBay or log into Facebook, that data is encrypted before it's sent to the server in order to prevent third parties from eavesdropping and stealing your sensitive information.
Our class had been assigned interviews with political representatives from different branches. In these interviews we asked questions that we had generated about their career position, advice to young activists, our government system, getting involved, and their opinion on certain laws. Here are the results from the two interviews that were done.
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.
Every state has begun reopening in some capacity. While there are important steps for everyone to get back to work and begin socializing, precautions will be in place for some time, especially with an expected second wave coming this fall. The virus is not over.
If you want your photos to look like they came straight out of a movie scene, the best method is to use split toning. Many Hollywood producers use this effect to recreate the cinematic look of cameras before the digital film era, which is why most people associate split toning with a cinematic feel.
In recent months, the Magic Leap One has frequently tied promotions to groundbreaking entertainment properties, but the latest may be the startup's biggest coup yet.
Last week, Twilio showed off how avatar-based chat communications will work on the Magic Leap One, and now a new startup has unveiled yet another way that augmented reality telepresence and remote collaboration can take place on the device.
In the world of technology, there's often a trade-off between convenience and security. The Java Remote Method Invocation is a system where that trade-off is all too real. The ability for a program written in Java to communicate with another program remotely can greatly extend the usability of an app, but it can also open up critical vulnerabilities that allow it to be compromised by an attacker.
Personal data is a hot topic right now, and for good reason. Never before has the public been so on edge about how companies use their information. Services like Facebook and Google now allow you to download all of the data each has on file. Soon, you'll be able to see exactly the same for Apple as well.
With Huawei's recent emergence as the second largest OEM in the world, the company was poised to finally make a big push into the US market. Instead, their efforts were derailed by an unlikely foe, the US government. As a result, American customers will miss out on the newly-released Huawei P20.
A core concept that has resonated through societies of the world over the course the last few hundred years is "knowledge is power." And understanding that concept gives us the drive to push further forward and learn as much as we can on a subject. At the moment, that subject for us at Next Reality is the recently released information about Magic Leap's upcoming Magic Leap One: Creator Edition.
Another piece of Magic Leap's mysterious story has been uncovered thanks to a new patent application revealed on Thursday, March 15.
IFTTT (short for If This, Then That) is an amazing piece of software that automagically links actions on your phone with online services and real-world objects. For example, an applet could read: "if you come home, then turn on Wi-Fi." IFTTT goes further than just using simple smartphone functions, though — thanks to applets, it's fully configurable with a ton of smartphone apps.
This is a tale about microbes, a man who became a hermit, and the parchment that carries both of their stories.
A vaccine against HIV might prevent the disease that we can't seem to cure. Some HIV patients make antibodies that can take down the virus, much the way a vaccine might. But, scientists haven't been able to provoke that type of response in other people. However, in a process that might work in humans, a group of researchers has successfully generated antibodies in cows that neutralize multiple strains of HIV.
How can a drug used to treat cancer be effective against viruses, too? The answer lies in the drug's shared target — specifically, cellular components that control the activity of genes. A new research study showed that one such type of drug, histone methyltransferase inhibitors used in cancer clinical trials, has activity against herpes simplex virus, too.
If you haven't been on any sort of social media all day — which I seriously doubt — then you might not have heard that today, June 30, is Social Media Day. It's been trending on Twitter, but has also been making appearances on Instagram and Facebook. While major influencers are talking up a storm about this, most people are simply asking "what is social media day?"
As researchers from Yale searched our environment for compounds to aid in the battle against drug-resistant bacteria, they got an unlikely assist from ticks.
Could your fever, body aches, cough, and sore throat be the flu? Soon, finding out may not involve a trip to the doctor.
LOOOK, a Seattle-based mixed reality and development studio, can now peer into the future with their new geotechnical engineering visualization application for Microsoft HoloLens.
Somewhere around 600–800 million people in the world are infected with whipworm (Trichuris trichiura), an infection they got from ingesting soil or water contaminated with feces of infected animals or people containing the parasite's eggs.
