In this article, I'll show you how to make an awesome "Death Ray" using the large magnifying lens from an old projection TV. The lens is called a Fresnel lens; a device that employs several ridges to focus light, rather than a complete curve.
Okay folks, I've finally finished my underground ancient city. Actually it's more like, I need to move on to other things and really should stop obsessing over this thing already. You can find it at the warp location "woodcity" - which is funny because there is not a stick of wood in it! That's the idea: the city is so very, very old that nothing but stone (and some conveniently located, er, naturally burning torches and lava and ice deposits) remains to be seen today. All is enveloped in the...
This is the first thing I have ever built for a weekly challenge. I am a big sci-fi fan so I just had to jump in on this one.
Eric Gjerde is a master of origami who devotes much of his energy on origami tessellations. Some of his pieces fold nearly flat, forming layers that add just a hint of depth. These pieces look beautiful when lit from behind, due to the variations in brightness and color. Other pieces utilize three dimensions more fully, with repeated structures rising out of the flat page.

If you're willing to shell out for a mind-blowing party trick, here's another great one to add to your repertoire. Unfortunately this isn't a dirt cheap junk drawer DIY—you'll need a $40-$60 gallium kit (which doesn't include the spoon mold). What is gallium, you may ask? An amazing, man-made metal which melts at the low temperature of 86 degrees Fahrenheit. Plunk your trick spoon into a cup of hot water, and amaze. According to the Department of Energy, it's safe to handle as long as you don...
I would like to quote a paragraph from The Power of Art by Susan Anderson, Nancy Walch, and Kate Becker. You will find the link to the PDF online booklet for more information at the bottom.
NOTE ONE: I want to ask everyone who reads this to please be patient with the progress of this website - soon it will be filled with goodies for you all to lay eyes on, but at the moment, I'm just piecing it all together for you :)
Think you're more green by going artificial? Think again. The New York Times reports that the most definitive study shows you would have to use your artificial tree for 20 years before it has less impact on the environment than a real tree.
Beginners don't realize that they don't need to clobber every groundhog that shows up. The best strategy is to isolate the first one someplace out of the way and just leave him there indefinitely. Only one can be on your property at a time.

How many gallons of gas does it take to get from Kansas City to New York? Depends on what you're driving. In this custom-modded Indy race car designed by students at the DeLaSalle Education Center? About four.
China's latest futuristic project is a massive "3D Express Coach", a clever project proposed by Shenzhen Hashi Future Parking Equipment Co. as a solution to traffic in the extremely overpopulated country.
Toy Story 3 has received rave reviews across the board. Curious, a couple of us here at WonderHowTo went to see it last night. We found it to be decent. Not fabulous. The opening was exhilarating. Full of action and humor and a thoroughly dynamic use of 3D, but the rest of the movie didn't exude the same energy. The story was sweet and touching, and the characters were as lovable as ever. However, I was looking for a little more action.
Sony's Bravia Balls Ad, David Michod's "Crossbow", James Nachtwey's war photography. Every once in a while, you get smacked in the face by art so powerful and sublime, it leaves you inspired, envious, or both. The mini documentary series, "California is a place", is no different. Led by filmmaker Drea Cooper and photographer Zackary Canepari, these 5-7 minute masterpieces tell the stories of unique individuals and groups throughout the Golden State. What really separates the quality of these ...
My friend from Brooklyn and I went to this free show on Monday. The vocals were crisp and less distorted than on the album. Overall great energy and the crowd was totally feeling it. The crowd was made of the typical mix of big messy hair, plaid, and skinny jean wearing indie kids, along with a few random old guys. My friend said NYC shows are a lot more homogenous and was surprised by how diverse shows in LA are. I was surprised by how many tall guys (lots of guys well over 6'2) were in the ...
Upon first glance, one may think Mark Suppes is just another thirty-something-year-old dude living in Bed-Stuy, Brooklyn. However, the Gucci web designer by day has a significant (to say the least) project-in-progress by night. The amateur scientist bicycles to a non-descript building in Brooklyn to chip away at his homemade nuclear fusion reactor. BBC reports:
This Japanese expression has two basic meanings. The literal meaning is to break one’s bone(s), as when falling from a height. The figurative meaning is “to try harder.” That is, to try so hard that one’s bones break.
Think about how many things you truly throw in the trash, and how many times you empty your trash, only to be taken away by the garbage man and out of your sight. Well, the truth is that its not exactly out of your life. Statistics show that on average each person uses 350 trash bags each year, thats 100 billion all together, and the worst part aboput this fact is that it takes up to 500 years for each of the bags to decay. Thats right in your city at your landfill, bags pileing up, polluting...
Researchers Hiroto Tanaka and Isao Shimoyama (of Harvard University and University of Tokyo) have constructed a tiny replica of the swallowtail butterfly. The crudely made model uses just balsa wood, rubber bands, and a steel wire crank. The goal is to better understand the biomechanics of butterfly flight. Via Wired,
Stephen Hawking asks: "is time travel possible? Can we open a portal to the past or find a shortcut to the future? Can we ultimately use the laws of nature to become masters of time itself?"
Everyone wants to know the optimal amount of time and energy for exercise. While estimates vary, Fit Relief helps you make maximize your workouts, whether you have 10 minutes or two hours.
I want my Android device to run how I want, and I want it to be useful and positively contribute to my life. Recently, animations have started appearing on the Pixel's search bar when Google has a seasonal Doodle on their front page. It attracts my attention and distracts me from what I think is important. After several days of annoyance, I went on the hunt to turn these animations off.
Fight anxiety with food Most of us get exposed to anxiety and social problems that increase depression.

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...

Hello! Today, I will show you how to add captions to your YouTube videos. Captions help people understand when the video itself does not entirely explain your tutorial.
As some of you Mad Science readers will remember, we recently covered the separation of water into hydrogen and oxygen using electrolysis. Passing a current through water can rend it apart, but we can also recombine that oxygen and hydrogen to make electricity! This is the principle behind those vehicles run by hydrogen fuel cell engines.
I'm sure most everyone has some kind of fluorescent light source in their home; those long white tubes that emit a bright white light when turned on, or maybe a few of the CFL power-saver bulbs. These bulbs actually require very little "power" (i.e. a high voltage:almost no current ratio) to emit light. In fact, static electricity is enough to make them flicker. Inside these tubes is a gas, and when electricity flows through that gas, it gets "excited" and produces light.
Diet = Die or Eat As Biological definition, food is defined as; any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals.
This is the third part of my electromagnetic pulse series (see Part One and Part Two). By now, I've covered the hardware and general concept of electromagnetic pulse generators, but how exactly do they disable electronics? How can an invisible field of energy have such a catastrophic effect on computers, cell phones, and most any other electronics? I'll be answering all these questions in part three of Making Electromagnetic Weapons.
In this article, I'll show you how to create a simple yet accurate demonstration of the "rising ionized gas" principle. In other words, a transformer, two metal prongs and lots of evil laughter. Remember those large "towers" in the background of Frankenstein movies with a "lightning bolt" rising upwards every few seconds? That's called a Jacob's Ladder; one of the coolest awe-inspiring demonstrations of high voltage. Here's a video of the final product: Materials and Tools
It's no secret that the Canon EOS 5D Mark II is being used in low-budget indie films, as well as big blockbuster movies from Hollywood. But it's also become a staple for television commercials.
Mobile devices can do just about anything these days, thanks to third-party developers. iPhones and Android devices have been known to do some pretty wild things. Need a dupe key made? Scan and order one with your iPhone. Want to know if you're hotter than Justin Bieber? Compare your facial features. Are you a policeman who needs to ID a suspect? Scan their fingerprints and irides. Want to control your Canon DSLR remotely? Use your Android phone.
NASA just released this beautiful image of what's leftover from a supernova explosion. The red cloud is expanding cosmic debris, the blue is a blast wave of electrons, and the stripes at the edge tell of a high energy burst of x-rays that may be bound for earth. This image was enhanced—Photoshopped—so that scientists can have an easier time interpreting the picture and so that the public can have an easier time appreciating the beauty of nature.
Your roommate swears by 'hair of the dog' or chugging raw eggs and tomato juice, but do these hangover cures actually work? What do the scientists say?
