News: Magic Leap CEO's Tweetstorm Tries to Reframe Reactions to Latest Demo After Signs of Disappointment

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.

Classic Chemistry: Colorize Colorless Liquids with "Black" Magic, AKA the Iodine Clock Reaction

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.

How To: Use Telegram's GIF & Sticker Search to Find a Perfect Reaction for a Chat

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.

How To: Make a permanent, reusable glow stick

Make a reusable glow stick, glow-in-the-dark-style! Imagine, you'll never have to buy one of those ChemLite's again, because you can reuse this homemade glow stick over and over again. 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.

How To: Make Glowing Green Candy

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.

How To: Understand reduction & oxidation in Chemistry

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.

How To: Make hydrazine sulfate with the hypochlorite and the Ketazine process

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.

How To: Measure pH levels with paper and meters

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.

How To: Make manganese dioxide electrodes

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.

How To: Make aluminum nitrate nonahydrate

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.

How To: Make TCPO (for making glow sticks)

How to make TCPO or bis(2,4,6-trichlorophenyl) oxalate, used in glow stick reactions. WARNING: This procedure should only be performed by, or under the direct supervision of, an experienced chemist. Please refer to the material safety data sheets of all chemicals for their hazards. Synthesis must be performed in a fumehood.
