Instead of responding to a WhatsApp message with short texts like "LOL" or thinking too hard about something meaningful to say, use an emoji reaction. They cut down on clutter in group chats and take up less space than typing emoji individually in a conversation. WhatsApp initially limited reactions to just six emoji, but a new update lets you use any emoji you want.
In this video, I'll be demonstrating how anyone can make their own iodine clock reaction with simple over-the-counter chemicals.
Have you ever run across a Facebook post that you don't necessarily want to "Like," but you're not really passionate enough about to bother stringing together a couple words for a comment? Well, you're in luck, as Facebook added five new "Reactions" that let you do more than just like a post, and they're now live for everyone.
Usually, flying into unknown territory would mean riding into the "danger zone", but Paramount and Snapchat are taking the trip anyway with one of Summer 2020's most anticipated movie sequels.
We've shown you how to make water change color on command, but how about just half of it? What if I told you that you can split a solution right down the middle and make the color disappear from one side, just by shining light on it?
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.
The updated Messages app for iPhone, iPad, and Mac has some really cool new features, but the one you may end up using the most is something you're already familiar with: Tapbacks. With iOS 18, iPadOS 18, and macOS Sequoia 15, Tapbacks are improved and contain even more reactions to choose from.
Apple's Messages app has long had visual effects you could apply manually after long-pressing the send button, and there are even hidden keywords you could use to trigger full-screen effects automatically. FaceTime can also give you some full-screen effects to play around with during video calls, but the triggers are an entirely different concept — hand gestures.
Sulfuric acid is mixed with sugar, which is attacked by the acid. The final products are carbon, water vapor, and sulfur dioxide gas.
Although it's impossible (at least for now) to travel back in time to see the Big Bang, The New York Times has provided its readers the closest simulation of the experience via its latest augmented reality feature.
Bitmoji are personalized emoji that look like you and can be used to make funny memes or snappy replies. Normally, you have to find one of these reaction emojis in the Bitmoji app, then use Android's share menu to send it to the app where you ultimately want to post it, but there's a much better way.
Former Google and Uber engineer Anthony Levandowski's scathing accusations challenging the physics behind Tesla CEO and founder Elon Musk's claims about Autopilot should force Musk to make his case that self-drive cars don't need LiDAR in the next few months.
Remember trying to express yourself over the 160-character limit on SMS texts? We've come a long way since then, and messaging services have nearly taken over with emoji, chat effects, custom interface colors, and other personalizations. Necessities for messages these days include GIFs and stickers, and Telegram makes it easy to find those perfect reactions for any moment.
This video helps us understand the organic molecules and elimination reaction. Take some sugar in a beaker. Sugar has 12 carbon atoms, 22 hydrogen atoms and 11 atoms of oxygen. The sulphuric acid is poured into the sugar and the color change is observed. The color of the sugar gradually changes into black. The sulphuric acid causes an exothermic reaction which releases a large amount of sulphur dioxide gas. All the water (containing hydrogen and oxygen atoms) is eliminated out of the sugar du...

Obtain finely powdered iron oxide (rust), aluminum, and a thin strip of magnesium. Mix them together in a 8:3 ratio (iron oxide: aluminum) in a ratio by weight. [Note that the since aluminum is so light, it will appear that it is about a 50-50 mix by volume].

There are many different kinds of bait that can be used when bass fishing. One thing that is used is spinnerbait. Although it's not live bait, it's still something that will attract the attention of the fish very fast. Find out more about spinnerbait, why it's good to use, and how to use it in the tutorial above. Enjoy!
This reaction is between metallic magnesium and carbon dioxide. Magnesium reacts with oxygen in the air to form magnesium oxide, but when the only source of oxygen is from CO2 the reaction becomes much more energetic. The products are white magnesium oxide and black carbon.

The very people this humanitarian mission seeks to help are outraged at the portrayal of their problems and lands. In my previous post, I talked about how this new internet sensation is most probably a hoax designed to force us into a new war. Guess what? It was.
Once you've reached an age where sparklers are no longer fun, it's time to upgrade to science and steel wool. It may be basic chemistry, but as you'll see in the video, simplicity can amaze more than complexity, as well as create some really impressive fireworks that are perfect for the Fourth of July.

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.
