In this video Dr. Carlson demonstrates the properties of light. Light is like a wave and it is also like a particle, which means that it comes in small packets. To demonstrate how we know that light behaves like packets of energy, he uses LED’s in different colors and a sheet of phosphorescent paper. When light with a high enough energy shines on the paper it will cause the paper to glow.
This video is a demonstration of how to make pumpkin soup the Vietnamese way. The ingredients are 1/2 pound of ground pork, scallions, fresh pumpkin, salt, pepper, sugar and fish sauce. Prepare the meat: mix the pork with 2 teaspoons of sugar, half a teaspoon of salt, some pepper and chopped up scallions (reserve some), and two tablespoons of fish sauce. Cut up the remaining scallions. Cut up the pumpkin and remove the skin. Boil four cups of water and a little salt. Drop chunks of pork into ...

This daring docu-drama explores the esoteric underground of hard-cider brewing. This fast paced thriller is sure to captivate the mind, and leave you on the edge of your seat. OK, it's just a video shot with a 3mp Cannon digital camera on video mode and edited with some lousy free software. There are two different methods used to make this hard cider. 5 gallons of fresh cider with a starting specific gravity of 12 were pitched with White Labs liquid English Cider Yeast. This should yield arou...
This film is about gold. Gold diving. Use of the hookah rig to find gold. Gold flakes, nuggets, and platinum nuggets are shown. Gold and platinum are 15-19 times heavier than other streambed materials and concentrate in low pressure areas and cracks that run across rivers and streams. You look for a crack on the bank, and follow it out until you meet the "gold line" and there you suck it out with your dredge. Gold will be on the outside edge of a river gravel bar, at the head of the bar (larg...
We've worked hard to reduce the flow of toxic chemicals into our waterways, which means no more DDT and other bad actors to pollute or destroy wildlife and our health. But one observation has been plaguing scientists for decades: Why are large quantities of one toxic chemical still found in the world's oceans?
Fluorescein is a commonly used fluorescent dye that is quite hard to come by in a concentrated form. Fortunately, it's used in relatively large quantities in highlighter markers and can be extracted by a fairly simple process. Fluorescein makes spectacular explosions of color as it dissolves into water and can be used for many different purposes that are addressed in the video below.
What Is a Rate? A rate is a comparison of two quantities that have different units. An example is 90 miles/3 hours, which is read as 90 miles per 3 hours.
Ask anyone that works on the development of driverless vehicle technology and there is a very good chance that AutonomouStuff will have supplied something to their project.
Common knowledge is a funny thing: it represents a majority's opinion on a particular subject and somehow makes that opinion fact. If that 'fact' goes unopposed and unchallenged, then it is passed on and preserved from one generation to the next—regardless of whether it is true or not.
Peeling apples is pure grunt work, especially if you have a recipe that calls for a lot of 'em, like apple pie. You can make this task go by much more quickly if you use something from your tool box—your literal tool box, that is.
No matter which brand you buy, microwave popcorn never tastes as good as its movie theater counterpart. Even if you pop it yourself on the stovetop and drizzle it with real butter, it doesn't have the same flavor. That's because movie theaters don't use real butter—their popcorn has one secret ingredient that gives it that distinct taste.
Hello, all. In this article, I will be showing you how to make one of the most useful products known to man. I am talking, of course, about charcoal.
In this article, I will be showing you how to make a crude form of aspirin from the bark of a willow tree. It is a great remedy for headaches, hangovers, and other minor pain. The use of the willow tree as a mild pain reliever goes back to the Native Americans, who used it in much the same way that I do.
Before my time, people used to listen to music recorded on these things... I didn't really know what this thing was until my parents clarified and told me that they were called cassette tapes. These "cassette tapes" were utilized to store sound recordings on either side of the tape, which could usually hold between 30 to 45 minutes. I laughed at that information as I took out my iPhone 5 (roughly the same size), which can store roughly 40,000 minutes worth of music.
A couple of months ago, I got the opportunity to get a sneak peek at a new media interface for ODG's R-9 Smartglasses, and the experience was impressive. Now, after weeks of keeping it under wraps, I can finally show off what I saw.
Fish is a remarkably useful ingredient, whether you eat it as is or use fish sauce to give your recipes extra depth and flavor. However, if you enjoy a glass of Guinness on occasion, you might be surprised to know that there's most likely fish in that beverage, too.
Chicken wings, pizza, beer, and chips are among the top five most popular Super Bowl foods, and we eat them in staggering quantities. According to the stats, Domino's and Pizza Hut sell over 25 million slices of pizza during the Super Bowl, and Americans snack on over 1 billion chicken wings, over 11 million pounds of potato chips, and drink over 49 million cases of beer.
For someone used to the old-style HTC Sense, upgrading to an HTC One with Sense 5 is a pretty intuitive experience, but there's one thing that some users find obtrusively different. Blinkfeed, an app which aggregates newsworthy articles from various sources and pins them in a scrolling feed on your home screen. If you don't like staying current on news, or don't like how much RAM it eats up, you probably want to get rid of it. There's been some questions about removing Blinkfeed in our forum,...
With the big reveal of the Magic Leap One: Creator Edition in December 2017, and now the update on Feb. 13, 2018, we no longer have to speculate as to what the augmented reality headset will look like or when (in general) it will be available.
Augmented reality headsets with larger eye boxes than any device currently available could make their way to market by the end of next year if current timelines hold true.
Do you know what your smartphone is made of? I've had smartphones for years, but if you asked me that question I'd probably respond with "Wi-Fi." For uninformed consumers like myself, it may shock you to know just how much goes into creating a smartphone.
At this point, I'm ready to give Apple CEO Tim Cook a piece of my mind. The hype surrounding the iPhone 8 is crazy, and rumors are circulating constantly. So many different things have been said about its release date that no one can even keep track anymore. If Cook could throw us all a bone and give us a hint, it would quiet the speculation. Unfortunately, it doesn't look like that'll happen anytime soon, but — in the meantime — a new report allegedly has the inside scoop. Recent rumors surr...
In the Western world, the only time you'd associate food with cockroaches is health code violations. And while other cultures and countries are more open to cooking with and eating these and other little buggers, insects are probably not a food trend that will be adopted by the West anytime soon.
Consider the radish. This root vegetable is so sadly misunderstood sometimes, and that makes us sad because we adore its spicy flavor and crunchy texture. We're always on the lookout for unique food items that can be turned into a dish of wow and wonder with just a few simple steps, and radishes truly fit the bill.
After a few years, your cinnamon, paprika, and saffron begin to lose their vibrant hues, and the aromas that once filled your kitchen are barely distinguishable when you open their jars. These are telltale signs that your spices need to be replaced sooner rather than later.
Amazon has completely changed the way we purchase household items, to the point where many of us haven't visited a big box, brick-and-mortar store like Walmart or Best Buy in years. And when you think about it, all of this success comes down to two main factors—convenience and price.
Rather than reaching for aspirin the next time a headache strikes, try grabbing a drink of lemonade instead. Not only can it help ease your head pain, but it can also help relieve stress, anxiety, and depression. But not just any old lemonade will do the trick—reach for the lavender lemonade.
Ginger root is one of the most underappreciated and versatile spices around. It's simultaneously hot, sweet, and piquant. It's also a pain in the tush to peel, thanks to its thin, fragile skin and the thick, knotty rhizome that contains all the flavor.
Editor's Note: The claims by Vani Hari which were originally detailed in the article below about azodicarbonamide were unscientific in nature. This article has been updated to reflect that and provide more scientific context on the issue.
If you've never played with a Nexus 10 tablet, then you probably have no idea that your Nexus 7 actually has a different user interface. For some reason, Google decided it was better for the Nexus 7 to use a phone UI instead of a tablet one, but luckily for us, we don't have to accept that.
Let me start out by saying that Steampunk isn't about being historically accurate, and that everything I'm about to tell you is entirely optional. That said, let's take a look at the history of screws! What many people don't realize is that before we had metal screws, wooden screws were in wide use for things like wine and oil presses. Generally, the invention of the screw is attributed to Archimedes in the 3rd century BC. That was a long, long time ago. Metal screws and even screwdrivers hav...
On Friday, audio giant Bose emerged as the latest, and perhaps the most surprising company to announce that it's planning to release augmented reality smartglasses.
Long admired for their active and cooperative community behavior, some types of ants also wear a gardening hat. Nurturing underground fungus gardens, these ants have a win-win relationship that provides food for both ants and fungi. If we humans understand it better, it may just help us out, too.
Have you ever had a burning sensation when you urinate? Low fever, back pain, and maybe cloudy urine? Male or female, it could have been a urinary tract infection. If it lasted long enough, the chances are good you went to the doctor for help. For about 20% of women, standard testing for a UTI does not reveal the presence of infection-causing bacteria, even though bacteria may be causing their symptoms. Well, a new test may provide better answers.
Our quest to find new antibiotics has taken a turn — a turn down the road, that is. A team of scientists from the University of Oklahoma is scooping up roadkill and searching for bacteria on them that might yield the world's next antibiotic.
As fun as it is to see Fido's face light up when you feed him table scraps, American dogs are getting fat. The good news is that research is homing in on nutritional strategies to boost canine capabilities to maintain a healthy weight.
Findings from a mouse study suggest that the Zika virus infection may have serious reproductive consequences for men.
New weapons are needed to combat antibiotic-resistant bacteria. Instead of drugs, scientists have discovered in an animal study that they may be able to harness vampire bacteria to vanquish pneumonia.
