Learn how to balance the three different types of chemical equations in simple steps. First take an equation, write down its reactants and products and write down the names of all elements. Now write down how many of each element are present in the equation. Now check which element does not match, in this case the Oxygen doesn't match. Now multiply the element or compound starting at two but now hydrogen doesn't match. Try to match them by multiplying the coefficients but now sulfur doesn't m...
This video teaches the secrets to sharpen a convex wood carving knife in simple steps. First find out how dull your knife is by cutting a paper or shaving hair on you hands. Now take a sand paper attached to a pad and start sharpening the ends by applying less pressure. Now try the sharpness of the knife, it will be better. Now take a double sided strop with sharpening compound and start rubbing the knife edge. After sharpening try the knife again, it should be good enough.

When installing baseboards, crown molding ("moulding") and chair rails, it's tempting to cut 45-degree miters at the corners and hope for a sure fit. The problem is that most walls aren't square. Joining two 45-cut molding pieces may give you a square joint, but a square joint may not work for your crazy corner. In fact, it seems like every wall is just a “hair” out of square. This problem could be due to a framing error or a buildup of drywall compound in the corner. But even a perfect miter...
German phonemes pronounced, each with example words. I tried to cover all letters and letter combinations which learners of the German language need to pay attention to.
Was Napoleon's death really due to stomach cancer, or was it arsenic poisoning? Some scientist believe the latter. Arsenic poisoning was a deadly weapon in that era, because it was undetectable when administered over a long period of time, making murder seem like natural causes. But if arsenic (As) is poisonous to most multicellular life, then what's with the newest NASA discovery?
Halloween is this weekend, so if you're looking for a last-minute big batch cocktail that will keep your guests properly hydrated—and might turn them into mutants—look no further! (Note: This will not actually hydrate anyone, just so we're clear. Priorities, people!)
Our quest to find novel compounds in nature that we can use against human diseases —a process called bioprospecting — has led a research team to a small frog found in India. From the skin slime of the colorful Hydrophylax bahuvistara, researchers reported finding a peptide — a small piece of protein — that can destroy many strains of human flu and can even protect mice against the flu.
Hydrazine sulfate has many uses, but most notably, it's been used under the trade name of Sehydrin, a treatment for anorexia, cachexia and some even think cancer. But for we DIY chemists, it's useful for something entirely different— as a substitute for the more dangerous pure liquid hydrazine in chemical reactions. NurdRage shows you how to make it via some hypochlorite and the Ketazine process.
This video shows you how to make non-toxic blue goo in your kitchen. You will need 3 eggs, two bowls, milk, coconut or vegetable oils and a spoon. First break the eggs and pour them carefully into the spoon to ensure that you can dispose the egg yellow as you will not need it. Repeat this for each of the three eggs. Then mix up the egg whites, ensuring that you do not beat the egg whites too much. Then add around four tablespoons of oil into the eggs and mix it up once more. As the egg whites...

Garlic isn't just a food, it's a legend. It's been found in the pyramids of Egypt and is referenced in the Bible. Hippocrates, the father of Western medicine, prescribed it regularly, and it was given to the first Olympic athletes in Ancient Greece to enhance performance (take that, Lance Armstrong). And, of course, it's famed for its ability to ward off evil, whether it's in the form of vampires, demons, or werewolves.
