Here at WonderHowTo, we love science. And of course, explosions. So, naturally we find Gray Matter's demonstration of fiery hydrogen bubbles pretty awesome. But the most interesting part is the reason behind the demonstration. Did you know the same gas that heats your house can also make it explode? Gray Matter explains why:
Light-weight, tiny, and easily doable, Mark Jurey's penny stove instructional demonstrates how to make a sleekly simple (and cheap) camping stove.
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).
He does say that it won't hurt current oil supply, but I think otherwise. According to the White House, it has calculated the risk and current world oil supply, but expect gas prices to rise. Reports say that they will peak at 4.25 a gallon.

From 1955 to 1975, military researchers at Edgewood were using not only animals but human subjects to test a witches' brew of drugs and chemicals. They ranged from potentially lethal nerve gases like VX and sarin to incapacitating agents like BZ.

I am anti-oil, anti-gas, and just anti-fossil fuel in general, which causes me some serious vaccilation of the mind when it comes to my enthusiasm for the do it yourself wonder material known as PVC. Even though I love this stuff for its properties, I really do not like the processes that go into making and disposing of it. That means I get happy when I see news like this.
Check out this how to video to learn how to do gas chromatography headspace injections. This is for you molecular biologists out there. Do a headspace injection into a GC.
Dimensional analysis is the process of analyzing units to decide which conversion factors to use. You can use this in real life if you want to figure your gas mileage. Here is a link to a website to help you Dimensional Analysis definitions | Quizlet.
The LED pollution dress: the ultimate tech + fashion + eco-friendly accessory. Danish design company Diffus recently introduced the Climate Dress, a garment with hundreds of LEDs that light up when air pollution is detected.
Airsoft doesn't get any better than a cloud chamber BB machine gun, aka Cloud BBMG. This design has an incredible rate of fire. If you've got a full charge of compressed air, it can easily fire more than 50 rounds per second at a 350 ft/s muzzle velocity. Since this is a legit airsoft build, it should be handled safely with the same care as any other airsoft firearm, and you should be wearing the same protective gear—protective mask, safety glasses, etc. My video details the build of this bea...
If you've ever had teeth removed/minor surgery, you most likely received some laughing gas, or nitrous oxide. This gas creates a happy, lightened feeling, and causes instant laughter. In this article, I'll show you how to make some. BUT BE CAREFUL!!! DO NOT proceed in this experiment unless you have EXTENSIVE knowledge of chemistry!!! Misuse of this procedure could result in the production of LETHAL GASSES! However, the set-up is quite simple, if done correctly should not lead to any issues. ...
This two-part tutorial looks at the basic techniques for emitting smoke from particles.
For the technique in this how-to video, you need: smoking papers, receipt or any thin paper and a hard surface like a cd case or book and a piece of paper on top for friction. If your lighter runs out of gas you can still start a fire with these items from your pocket. Watch this video survival training tutorial and learn how to start a fire with an empty lighter. Make a fire with an empty lighter.

Follow along with the steps in this how-to video, and put that money you save toward some gas. Remove dents from your car with dry ice.
When he's not taking orbital videos of Earth's auroras, NASA Astronaut Don Pettit is experimenting with water in zero gravity. He's already shown us how water droplets can orbit around knitting needles in a microgravity environment. Now he's playing with water again, this time—antibubbles.
News in a nutshell: Iran Boosting enrichment efforts
The Job Board is a weekly entry of the most ridiculous Cinematography related jobs posted online. Note: This posting was from a year ago.
In this experiment, we're going to get Mn2O3 (manganese(III) oxide) from MnO2 (manganese(IV) dioxide). Mn2O3 forms brightly red or a dark red colored crystal. It is used in Li-ion batteries, since (in a form of a crystal) it conducts electricity (much like MnO2).
Simple as the title, someone will particpate as a crash test dummy. The funny part of course the prank is the "particpate" will not know he is a crash test dummy. Its kinda like the prank that was pulled on Ryan Dunn in the addtional footage in the DVD of Jackass Number Two where an airbag was suppose to go off in his face. Well i hust thought of the same concept but add a 30 or if you want to go crazy, 40 mph crash into wall or whatever it may be. You would tell the person being pranked that...
CREMAINS n/pl the ashes of a cremated body 62 points (12 points without the bingo)
This is one concept that I would love to see sweep the urban world. One thing that strikes me every time I visit a major city is how far away they are from anything that is truly alive. Not only is the air dirty, but everyone must buy their produce from the grocery store. If those trucks were to stop coming for any reason, most people, if not everyone, would die of starvation. While this house is covered with ornamental plants, I would love to see this same concept applied to edible plants an...
A great pizza may take more than 20 minutes to make, but if you're using pizza-flavored snacks instead of fresh ingredients, you'll end up with a "Meta-Pizza" that's sure to please any junk food fiend. Health nuts, go away now, because you're not going to like what you're going to see.
From Boston.com's The Big Picture, what a real-life version of the Green Hornet's gas gun might look like. Taken in Afghanistan in February of this year, an Afghan army recruit is pictured shrouded in a cloud of shocking green smoke as he participates in a graduation parade after an oath ceremony at Ghazi military training center—an American effort to strengthen Afghan forces so they can fight against Taliban strongholds.

What's the difference between a paper plane and a paper space plane? Altitude! About 125,000 feet to be precise:
Some of these look like illustrations done by adolescent sci-fi/anime nerds. Totally unreal. A selection from National Geographic's best space pictures of 2010:
From Salon.com "AB 32 mandates that California must reduce its greenhouse gas emissions to 1990 levels by the year 2020. But California's crazy government-by-initiative system means that just because a law has been passed by the California House and Senate and signed by the governor doesn't make it secure. On the ballot this November, voters will get their own chance to weigh in on AB 32 by deciding whether or not to pass Proposition 23, the misleadingly named "California Jobs Initiative."
Making a difference can be done even before you leave your house... Are you thinking about a friend... maybe send them an email and say.. HEY I was just thinking about you... how are you doing? They could be surprised that you remembered... Many of us remember people but take little time to acknowledge it.... So when you are at the coffee shop this morning or filling up your car at the gas station. Wish them a "Super Dooper Day!" They might think you are on crack, but you will have made them ...
As a protest to American consumerism, NYC artist Jeremy Dean converted a Hummer H2 into a horse-drawn carriage "to show just how screwed and unsustainable the auto industry has become." Dean believes the gas guzzling SUV is the epitome of everything that is wrong with American consumerism. Whatever your political opinion may be, Dean's conversion is pretty striking.
Forget electric cars, quit mixing your at-home biodiesel; just attach one of Dutch John's handy wood gasification contraptions to the back of your car and fuel your transportation with backyard wood chips.
ProjectExciteBike is a device that harnesses the manpower pedaling speed of an exercise bike and in turn, converts the energy into a single control button on a gamepad (which would translate as the "gas pedal" for racing games). This particular project works with XBox 360, but can be adapted for other systems as well.
Rosemarie Fiore is badass. She makes art with pyrotechnics, amusement park rides, Atari, guns, and pinball machines. Though all of her work is cool, I have to say my favorite piece is Fiore's larger than life spirograph, made from an amusement park ride, entitled "Good Time Mix Machine".
Mountain Dew is the answer. Inventor Paul Patone has devised a mechanism that converts soda into actual usable fuel.
Michael Faraday knows how to harness static electricity. The television sends enough static electricity to the aluminum to spin the cup between the polar charged cans.
Wait...with only your hand? It's simple. Take a normal Bic-style lighter. Hold down the button to release butane gas into your cupped hand. Then light it.
Yes, plasma. The fourth state of matter. What's going on? The sparks result from an electrical discharge between the sides of the grape. If the flashes of light are not enough evidence, enjoy the 120Hz buzzing.
Defy logic and gravity with this quick magic-science illusion. All you need is lighter fluid, a bowl and some bubble solution. The butane gas from the lighter sinks to the bottom of the bowl, below the oxygen. The bubbles then float in the oxygen atop the heavy butane creating a magical hover effect!
