Chlorine gas is a very useful oxidant, which was first introduced as a toxic weapon by the German Army. Even today, it's still used as a weapon, most recently in the Iraq War by insurgents. But chlorine gas has more useful (and less lethal) applications, and if you want to learn how to make some at home, NurdRage has the answers.
Everybody into the pool! Or the ocean! But not before you take measures to prevent your hair from getting fried.
This is a science experiment illustrating the reaction between chlorine, sodium & water.
Chlorine gas is bubbled up along with acetylene gas through a large graduated cylinder filled with water. Where the bubbles of the two collide, an instantaneous, bright flash of light occurs.

New techniques may improve a swimming pool workout from Masters coach Nancy Kirkpatrick Reno. Before sticking a toe in the water, consider this advice: * Swim in a pool that's at least 20 to 25 yards long; those pools can usually be found at high schools and some gyms. A 50-meter Olympic-size pool is best, but not everyone has access to that. "If you're going to become a lap swimmer," Kirkpatrick-Reno says, "you can't go any shorter or you'll be constantly turning." An outdoor pool is prefera...

Lowe's home improvement expert Mike Craft gives the low down on how to maintain your swimming pool. Pool maintenance is essential for keeping your pool like new and in tip-top condition. You will need some basic materials such as water test strips, chlorine tablets, algae-cide, water shock, a skimmer brush, pool net and vacuum. This video will show you how to balance your water, shock the water, clean out the filters and sweep and vacuum out your pool.
The proper steps to close your swimming pool. The temperature in your region will be the key deciding factor on whether to close your pool or not.
Cut out the old caulk with a utility knife. Trim along the sink where the old caulk was located. Scrape out stubborn caulk with a putty knife or a paint scraper.
Your ironing skills are rusty, and so is your iron. Now you’ve got rust stains on your blouse. What to do?
Prevent infection by keeping your ear, nose, lip, tongue, navel, eyebrow, and other body piercings clean.
Remove mildew as soon as you see it: not only is it gross, the longer the mold is allowed to grow, the more damage it can do to surfaces and even your health.
It’s time for science. You are able to calculate the molar mass for a compound using the periodic table and the amount of compound involved. You might need to know this in your everyday life but you will definitely need this in a chemistry class.
When Apple announced its new iPhone 7 and iPhone 7 Plus models in San Francisco, one of the biggest new features was an "IP67" water-resistance rating. Couple that with a few official renderings that show the new iPhone covered in water, and you'd probably arrive at one logical conclusion: The iPhone 7 is waterproof.
Food labeling is a tricky beast. For instance, when I read the words "cage-free" on an egg carton, I think it means that happy chickens frolic in a sunlit meadow all the livelong day until they're gently herded into a clean, sweet-smelling coop to lay a few dozen eggs—which I can purchase for a reasonable price, of course.
In its latest feature with an assist from augmented reality in storytelling, the New York Times shows readers the virtual crime scene it constructed to prove that the Syrian military conducted chemical warfare against its citizens.
With summer just ahead, you, or your children, may be looking forward to some pool time or the water park. When planning water-based fun this year, keep a heads-up for microbes.
They're finally here. Apple announced three new iPhone models at their "Gather Round" event in Cupertino, and they're all absolutely gorgeous phones. With bezel-less screens and polished titanium edges, the iPhone XS, XS Max, and XR are truly marvels of engineering — but perhaps the most impressive design feat Apple pulled off is the fact that two of these models are rated IP68 under the IEC standard 60529.
In case you didn't catch the big event in Cupertino, Apple just unveiled two of the most cutting-edge phones ever made — the iPhone 8 and the iPhone X. Out of the many glorious specs that were rattled off on stage, one stands out for being just a little confusing: Both models are rated IP67 under the IEC standard 60529.
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?
I own two aprons—a cute one for company, and another for the hard-core cooking duties, like cutting up chicken and making stock. The sad truth is that I almost never remember to wear either of them. So, much of my clothing ends up spattered with grease, liquid, and bits of fruit and vegetable. While stain-removing sprays, sticks, and pens are all effective to a certain extent, they have two drawbacks—they're expensive and sometimes I need to use them in large quantity, like when a piece of eg...
Samsung's new line of Galaxy S20 flagships have a water resistance rating of IP68. This means you don't have to worry as much about getting the phones wet, but there's a limit to that.
Most of you probably spread ketchup all over hamburgers and fries. Some of you may even drink it straight. But did you know that tame (and slightly addictive) condiment in your fridge is also a powerful cleaning agent?
As a pale white boy growing up in Florida, you learn how to deal with sunburns. Most people will say to take cool showers to relieve the heat, but that only temporarily alleviates symptoms. The problem is that the sun has evaporated the moisture from the skin. The answer to relieve the stinging and pain is to re-moisturize the skin. I've done this countless times and it always works.
Samsung's not one to make drastic changes to what already works. They've continued on with the IP68 rating under IEC 60529 first given to the Galaxy S8 all the way to the the Galaxy Note 10. If you're a little confused as to what this rating means, don't worry, it's actually pretty simple once you get to the meat and bones of it.
When it comes to resistance to the elements, Samsung seems to believe in the old saying "if it ain't broke, don't fix it." They've carried over the IP68 rating under IEC 60529 that was first found on the S8 all the way to their tenth-anniversary flagship, the Galaxy S10. While this certainly sounds great on paper, it's natural to want to dig a little deeper and find out what the rating means.
Norovirus outbreaks occur all year long, but peak in the winter months, which means we are in the middle of norovirus season. But there's still time to protect yourself from the highly infectious bug.
My morning just doesn't start without a cup of coffee and an incredibly hot shower. There's nothing better than sloughing off sleep with a dose of warm, cleansing water. Except, as scientists are pointing out, our habit of showering daily isn't exactly the healthiest choice. Though it feels great, if you have a shower-a-day habit like I do, you're showering all wrong.
After months of waiting, the iPhone 11 is here. At an event in Cupertino, Apple unveiled the iPhone 11, 11 Pro and 11 Pro max. You probably have a lot of questions after reviewing the specs sheet, including wanting to know more about the IP68 rating that all three phones have. We're here to clarify.
The day has finally arrived — Samsung has unveiled the Galaxy S9 and S9+. Apart from minor upgrades, the two might not appear to be much different from last year's S8 and S8+, but that's not necessarily a bad thing. One feature that hasn't changed is the Galaxy's IP68 water-resistance rating. That's a great score, but it begs the question — what does that number really mean?
Not to be outdone by Apple and it's new line of flagship phones, Google has followed suit and finally announced the followup to their highly regarded Pixel line of handsets — the aptly named Pixel 2. Thankfully, the tech giant has also joined in on the trend towards more durable devices, and has engineered both the Pixel 2 and Pixel 2 XL to have a rating of IP67 under the IEC standard 60529.
Look no further than Flint, Michigan, to discover the serious consequences of contaminated drinking water. Around the world, water polluted by pathogens and toxins sickens people or cuts them off from safe drinking water. Looking for a solution, researchers created tiny, swimming robots that pack a powerful punch against waterborne pathogens.
Mixing water and electricity is extremely risky and potentially lethal, yet that's exactly what I did with the Scariac. In its simplest form, the Scariac is just a glorified version of two wires in a bucket of water, but it's actually one of the cheapest power controllers you can make.
Once again, Samsung has certified its flagship Note series with an IP68 rating. With this rating, the Galaxy Note 20 and 20 Ultra have some degree of dust and water resistance.
