If you want to know the best way to get an accurate pH measurement, this shows the lab equipment needed and the processes used. When doing chemical reactions, sometimes the acidity or the basicity is important. This is usually defined as pH and measuring it can be very useful for getting the reaction right. There are a few ways to measure pH, and the simplest, cheapest, most reliable method is paper. But that's not all. See a whole lot of ways in this two-part video.
Splits are popular in dance and cheerleading, do you think you can do one? Practice, practice, practice and check out the helpful tips in this video to avoid injury.
Various electrochemical reactions requires that anodes do not degrade when used. Carbon is cheap, but degrades easily and platinum is extremely expensive. In a previous video, you learned "How to make cobalt and manganese nitrates", and you saw that titanium could be used as a cathode, but not as an anode due to an effect called passivation.
In order to make manganese dioxide electrodes, you're going to need cobalt nitrate and manganese nitrate to do it. Making cobalt nitrate is fairly easy, but making the manganese nitrate is a little more complicated. But not impossible.
What is MnSO4 and MNO2, anyway? They are they molecular formula for Manganese Sulfate and Manganese Dioxide. And you can make one from the other. But how?
This video speaks to everyone who has ever bought anything online, or in fact, anyone who has ever bought anything period. How do you know what you're getting is genuine? Is it a fake product? Is it stolen goods? Is it impure?
You already know how to make sulfuric acid with the metabisulfite and oxidizer method and you saw how to make copper sulfate from copper and sulfuric acid, so now try making sulfuric acid with these two in mind… with sulfuric acid by electrolysis of copper using an inert anode.

Before you start dissecting the body of a human being, there are a few things you should probably learn first. This anatomical look at the human body will give you just what you need to delve into your human dissection. Just watch this video tutorial on a few bony landmarks you should be aware of by palpating, like the clavicles, the sternum and sternal notch, the rib cage, and the pelvic region.
After achieving viral and financial success with its Gender Swap and Baby Face camera filters, Snapchat has returned with the augmented reality equivalent of Benjamin Button.
Homemade Halloween costumes that exhibit the maker's creativity are always better than off-the-shelf versions. It turns out that the same is true with virtual costumers.
Next to map data overlays, one of the most often discussed concepts for apps that could propel augmented reality smartglasses into the mainstream is a real-time language translation app.
After testing the waters with a few pop-up stores along the West Coast earlier this year, North is bringing its smartglasses to more cities across the US and Canada.

New York City may not be the friendliest city, but with the apps Via and Curb now letting users ride-share in the city's yellow taxis, New Yorkers can expect to snuggle up close in the back of a cab next to complete strangers. That's right, get ready to feel the love.
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!)
We at Food Hacks Daily freakin' love Halloween—it's the perfect time for weird and creepy food. The gruesomer, the better.
Ah, ginger. From stir fry to smoothies, ginger is a reliably sharp and refreshing flavor that adds zing to everything it touches. It may be a pain in the ass to remove the skin from ginger (or not), but the zest it brings to food is well worth the trouble. Don't Miss: How to Brew Your Own Ginger Beer Like a Boss
It's fall—so whether or not it's cold in your part of the world, it's time for apples and anything apple-related. (Please, don't get me started on pumpkin things. Seriously.)
Humans learn best by doing or through an experience, and so the holographic environments provided in virtual and mixed reality are ripe with educational opportunities. HoloStudy took this to heart and created an educational science app that teaches you with animated models you can explore in your own space.
A whole grilled pineapple is the perfect party dessert. It's beautiful, provides a natural centerpiece before you eat it, and can be sliced right on the spot and served with a dollop of ice cream. (Fresh mint leaves and a splash of liqueur on top taste pretty good, too.)
We all know that opening our work emails at home is a bad habit. Yet reading and responding to emails every time your iPhone dings is worse than you might realize. Not only are you extending the workday, but you are also sacrificing your ability to perform on a daily basis.
We're living through the technological revolution, and while devices like the iPhone 6 or Galaxy S5 have made life easier and more entertaining, it's possible that sometimes our smartphone usage can become uncomfortably excessive. In your own experience, think about how anxious and off you feel when you leave your phone at home—Cell Phone Separation Anxiety or Phantom Phone Vibrations shouldn't be a real thing that we deal with.
Google I/O may still be a couple of months away, and although we don't expect anything groundbreaking—no new Android versions, just fixes to KitKat—we could be treated to some new apps. No, not Pokémon inspired Maps, rather new versions of Google's Calendar and Gmail apps.
The first thing I do when I wake up in the morning is run to the kitchen to make coffee, and I know I'm not the only one. According to a survey by the National Coffee Association (yes, there's such a thing), 83% of Americans drink coffee, and I'd bet most of that consumption happens in the morning.
Applications, features, and software running in the background of your Samsung Galaxy Note 2 can drain a significant amount of battery power, even when your smartphone isn't being used.
