Chemical engineers at Cornell have created a small device that may one day turn troops into real life spider-men. The device would cradle in the palm of the hand, allowing troops to scale walls. It uses an adhesive inspired by the Floridian leaf beetle, an insect that "can adhere to leaves with power 100 times stronger than its own body weight".
Cortisone containing topical ointment and creams have various effect on the skin depending on its chemical nature plus the concentration of cortisone within it.
Enjoy the deliciousness of a peanut butter sandwich without the artificial chemicals that comes in store-bought jars. To make your own peanut butter at home, all you need are pre-roasted peanuts, peanut oil, and a little bit of salt and sugar.
If you want to keep the inside of your car smelling awesome, don't buy commercial air fresheners. They contain toxic synthetic chemicals which can be harmful to your health.
We've seen compressed air power a homemade rocket, shoot erasers across the room, and even remove dents from a vehicle, but how about breaking a bike lock?
Incredible. A company called Berry Plastics (in partnership with the U.S. Army Corps of Engineers) has developed a working bomb proof wallpaper. The technology has the ability to protect against both natural disasters and warfare.
Trippy! Get the kids around the table for this one.
This one starts out pretty tame with the water prank. But rest assured, the second round pen prank satisfies. We very much appreciate the 'safety' of adding water to the pen body in case the flame gets out of control. Nobody laughs at third degree burns.
I have an absolutely wonderful time making projects and writing articles for all of you mad scientists! Today, I will bring you behind the scenes for a look at the workbench, tools, and software that make the Mad Science World possible.
Watch this "Grease On Your Hands" video tutorial from the Washington Post to see how to change your dead car battery properly.
Jezebel's back with another Beauty 101 (1, 2, 3), and this time the issue at hand is body odor.

Jezebel readers also address problems such as pit stains, excessive sweating, and natural deodorant alternatives.
Baking soda and vinegar chemical reaction that results in H2O and CO2. More demonstration than instruction, this video does show you the grade school experiment of putting vinegar and baking soda together. Make H2O and CO2.
I have looked into this several times because I find it interesting to think about how the tongue works when making a recipe. I say "looked into" it because I wouldn't really describe it as research. How the flavors are going to be perceived can affect how you might want to layer the flavors in your dish. This information mostly comes from an artical in How Stuff Works website. There are several parts of the tongue that you need tobe familiar with when you study it.
Halyomorpha halys, squash bug, shield bug ... What's in a name? A pest is a pest and the brown marmorated stink bug is a pest par excellence. Though some home gardeners are content to use insecticides, you'll find that it's generally easier to work with nature than against it. And let's face it: trading noxious bugs for noxious chemicals isn't much of a victory. Particularly if you're growing food.
Sputnik, Apollo and the Space Race. If you watched the State of the Union address last night, you probably heard President Barack Obama mention those three things.

What's so great about Mineral Makeup anyway? Mineral Makeup is by nature, a long-wear, water-resistant product. This means less touch-ups and lasting coverage-even in the summer! High quality minerals are lightweight, inorganic and non-comedgenic. "Inorganic" means that bacteria and microbes cannot live in the makeup. This means less clogged pores, and no infections leading to nasty breakouts!
Last week I did some beach camping at the San Onofre State Beach "Trails" and my experience was less than satisfactory. I'm hoping that by reading what happened through my trip, you'll be able to plan for a better trip.

Pranks are fun, but finding a way to maximize the affect of a prank can be tricky. Toilet papering the whole campus or repainting all of the parking spaces slightly smaller can take a long time and a lot of resources. A better plan of attack is to booby trap the choke points where your victims are forced to pass through. Think like a guerrilla. A dorm doorway is a good idea.
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...
Writing secret notes with lemon juice was one of my favorite pastimes as a child. All it took was a small flame to lightly scorch the paper and reveal the hidden message. Now that I'm tall and pay bills, lemon ink just isn't exciting enough anymore. Luckily, we can use another kind of invisible ink to write in fire! By using the saltpeter, we can whip up invisible fire ink in no time.

For our final part of recognizing crowd control, we shall look at the mind. It's the most complicated thing in the universe, but also the most easily influenced. What makes us to gullible? What methods to commercials, companies and the media use to influence our position on things? These are just a few of the questions we will answer.

In this series, I'll be exploring electromagnetic weapons, how to build them, their function and application to the future, and the amazing possibilities electromagnetism has to offer. First, the electromagnetic pulse generator, or EMP. You've probably heard of these before, and their devastating effects on electronics. A simple EMP consists of a capacitor, transformer, trigger, and coil of copper wire. This, when triggered, would produce an intense magnetic field for a brief period, similar ...

Below, how to instantly upload via smartphone, plus a quick run through of the basic editing tools available.
If you found the world renown Body Worlds exhibition gnarly and perverse, perhaps you'll find this latest parade of plastination a little less so—considering we don't share the same DNA as these specimens of jerky-in-the-name-of-science. The Koerperwelten der Tiere—or Animal Body Worlds–doesn't showcase preserved corporal matter, but rather 20 odd plastinated mammals, currently on display at the Cologne Zoo in Cologne, Germany.
Alas, today we continue on the journey to a more environmentally conscious way of being with part 2 of How to make your beauty routine more eco-friendly. Check out part 1 here.

OK, so you don't necessarily have to make ammonium nitrate to have ammonium nitrate — ammonium nitrate can simply be obtained from fertilizers and instant cold packs. Making homemade NH4NO3 can be much more expensive then buying it, but this method is not meant to be a viable route, it's an exploration of science and chemistry.

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. ...
If you're on a tight budget for food, whether you're in college, or someone just starting out living on their own, you're probably low on money and sick of ramen noodles. Don't get me wrong, ramen can be tasty and filling, and there is almost nothing cheaper.
