You probably already know that cooking involves a ton of chemistry. Bread rises because of the reaction between the flour and leavener, and the delicious crust on your steak is formed by the Maillard reaction. Understanding the chemistry going on behind the scenes is one of the best ways to improve the quality of your food—it's much easier to fix a problem when you know what's causing it.
When you come home from the grocery store, you probably put away every single fruit and vegetable in the bins and drawers in your refrigerator. Any fifth grader knows that fridges work to preserve food, thus everything should go in there, right? Nope!
You have an abundance (or scarcity) of alcohol, liqueurs, and chasers, but don't know how to combine or mix them together to produce some kind of enjoyable concoction for friends. What do you do? Mix things you think will taste good together? They probably won't. There's rules about clear alcohol vs. dark alcohol and how they pair with juices and sodas, so what's the best way to know what goes well with what?
Making your own alcohol at home sounds like fun, but it's a long, complicated, and sometimes expensive process. You need all sorts of equipment, and by the time you're finished, it's been a few weeks—even months.
While the pope himself may not be Steampunk, you might be amazed at what is: the coronation stove. For those who don't know, it's been a tradition for a very long time to signal the election of a new pope (or the lack of a new pope) via colored smoke. More specifically, once the cardinals have all voted for the new pope during the conclave, the ballots are burned in a special stove in the Sistine Chapel, and the smoke is visible in St. Peter's square.
As practically the entire Steampunk world knows by now, IBM has predicted that Steampunk will be the big new trend from 2013 to 2015. They based this prediction on their computers, which sift through broad swathes of the internet in order to see patterns that may help commercial industries. According to them, Steampunk has been on the rise for the last few years, and they predict that it will explode into peak popularity within the next two years. But what does that mean and how will it impac...
Want to make boring old colorless water brighten up on command? Well, you can control the color of water with this little magic trick. Actually, it's not really magic, but a classic science experiment known commonly as the iodine clock reaction, which uses the reactions between water and chemicals to instantly colorize water, seemingly by command. You can use different colorless chemicals to produce different colors, and you can even make the color vanish to make the water clear again.
Once you've reached an age where sparklers are no longer fun, it's time to upgrade to science and steel wool.

What is a cataract? A cataract is the clouding of that internal lens of the eye which is normally clear. That internal lens helps focus light as it comes through the pupil that when a lens starts becoming a little cloudy, patients sometimes complain that their vision seems a little foggy. There are certain risk behaviors that you can avoid to reduce the risk of getting cataracts. Get professional tips and advice on cataracts in this medical how-to video.
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 animated video, produced by Jewish Pathways, demonstrates how to wash your hands in accordance with Jewish law before eating bread. Besides cleanliness and holiness, the instant reason the rabbis call for washing before bread is to keep alive the memory of the proper treatment of teruma (the first priestly tithe that may be eaten only by kohanim and their instant families, and that must be eaten only in the absence of any tum’ah – ritual defilement).
When Christians are out celebrating Christmas this year, Judaists will be out celebrating Hanukkah, or Chanukah, which is a lesser Jewish festival that lasts eight days from the 25th day of Kislev (December), and commemorating the rededication of the Temple; it is marked by the successive kindling of eight lights.

You may be wondering what exactly makes the Pixel 4a's camera so great. Compared to its predecessor, it has the same Sony IMX363 sensor and no additional hardware. Well, beyond stellar image processing, it also has several great new features that Google has added since they released the Pixel 3a last year.
The camera on models in the iPhone 11 series includes an ultra-wide lens to take wider images, Night mode for taking better-looking photos in low-light environments, and a 16:9 frame for shooting. With these new features comes a slightly redesigned interface in the Camera app, one that even the second-generation iPhone SE received despite only having one of those three features.
It's always a big deal when the company that makes Android releases a new phone. Google's Pixel series has made a name for itself in three short years behind its camera prowess, but now it's time to start competing with the major players. That said, Google should like how their Pixel 4 and 4 XL stack up against the iPhones and Galaxies of the world.
While iOS 13 introduces over 200 new features for your iPhone, one of the biggest focuses this year is Photos and Camera. The update completely overhauls the Photos app, creating a more organized and natural way to interact with your pictures and videos. You'll also find a few new tricks in the Camera app. In all, Apple has added over 30 new features to your shooting, editing, and viewing experience.
