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.
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.
Magic Leap CEO Rony Abovitz doesn't engage in tweetstorms often, but when he does, those tweets are bold, exceedingly confident, and there's usually a strong takeaway regarding what the company is or isn't doing. But on Thursday, Abovitz's latest tweetstorm sent an unusually flustered message: We promise, the magic we're telling you about it better than anything you've seen on video.

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.
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's latest update also gives you some full-screen effects to play around with during video calls, but the triggers are an entirely different concept — hand gestures.
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.
In this video, I'll be demonstrating how anyone can make their own iodine clock reaction with simple over-the-counter chemicals.
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 tutorial will show you how to make a permanent, reusable glow stick. The materials in this experiment are simple: epoxy resin, straw, and some phosphor powder.
If there ever was a day to eat green candy, St. Patrick's Day would be it. But is there something better than the banality of green candy swarming the streets on St. Patty's Day? Yes—glowing green candy, and Instructables user BrittLiv wants us to show you how it's done.
Curious about reduction & oxidation? In this two-part episode of The Science Catalyst hosted by Barry Lambson, the subject of Chemistry, reduction & oxidation is gone over with iron powder and copper sulphate. Oxidation and reduction are heavily related which is why they are both considered "redox reactions". Acids and bases may be thought of as reactions involving hydrogen, or protons, while redox reactions tend to be concerned with electron gain and loss.

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.
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.
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.

Aluminum nitrate nonahydrate is a crystalline hydrate - a salt of aluminum and nitric acid - Al(NO3)3·9H2O. It's used for a variety of things such as antiperspirants, corrosion inhibitors, and petroleum refining, or… glow-in-the-dark powder. Watch this science video tutorial from Nurd Rage on how to make aluminum nitrate nonahydrate with Dr. Lithium.

If you've figured out your short-field approaches and landings, then it's time to tackle "soft-field" approaches and landings. As a pilot, you need to be able to perform all types of landings, and you have to be prepared for inadvertent reactions in the air and on the ground.
Have an interest in nukes? Look no further. Learn about nuclear reactors, bombs, & reactors in this six-part video lecture by Professor Richard Muller of the University California, Berkeley. This lecture is from the spring 2006 webcasts of "Physics For Future Presidents". From the videomaker:
Check out this video tutorial on how to make a fiberglass mold layup for car speakers. For fresh molds you must put several layers of wax on and I would consider PVA as well if the mold is less then a week old. Always use PVA (or equivalent) on your plug surface before molding.
Chemistry can be very fun when you create different kinds of reactions between elements. Note that caution should be employed to not harm yourself while performing these reactions. Ammonium Tricynate reacts with barium hydroxide octahydrate in endothermic form. Endothermic reactions are those which absorb heat from the surroundings during the reactions as opposed to exothermic reactions which produce a lot of heat during the reaction. When endothermic reaction occurs, depending up on the inte...
