Glow sticks, a popular favor at parties and outdoor events, and a must-have on Halloween, can be traced back to the United States Navy in the mid-1960s. The military desired improved visibility during night operations, and glow sticks, with their small-size portability and lack of batteries, were a perfect tactical solution.
If you're like me, then you're rarely just watching TV. You're probably also simultaneously following reactions on Twitter during a live airing of The Walking Dead. Or perhaps you're checking your fantasy football scores while a real game is in progress. Or you might just have the TV on in the background while you're writing an article about a new augmented reality app.
A sphere of clear gelatinous goo may not sound all that appetizing. But to food fad fans on social media, the raindrop cake—a soft and lightly flavored edible blob—has gone insanely viral.

Is it possible to cut or chop onions in the kitchen without stinging eyes and looking as if you just watched the saddest movie ever? Before we get to that answer, it's important to know why we tear up when cutting raw onions in the first place. What is this irritant? Are you reacting to the odor? The answer to the latter question is "no," and the irritant responsible is amino acid sulfoxides.
If you're a medical student, you'll learn a lot from this video lesson on examining your patient's eyes. If the patient is having trouble seeing, like double vision, blurred vision, pain or any other problem, a proper eye examination is detrimental to properly diagnosing and treating him/her. You can also determine and potential problems which may arise bases on your family history. Watch to see the complete procedure outlined, which is great for any med student or doctor. Even nurses can ben...
As a doctor, sometimes it will be necessary to perform a neurological examination of your patient to rule out any neurological disorders.

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.
Apple's Tapback is a great way to react to iMessages you find funny, surprising, confusing, and anything in between. However, in group chats, keeping track of who reacted with which Tapback can be difficult; iOS often just shows you how many people reacted but excludes many of the names. Luckily, there is a way around this — it's just a bit hidden.
This week's Apple earnings offered a report of solid performance and guarded optimism about future iPhone sales, which may be impacted later this year by issues around the current coronavirus epidemic in China.
Among all the new Magic Leap app announcements made at the recent L.E.A.P. conference, an update to one of the company's major in-house apps went mostly unnoticed: Create 1.1.
Ever since iOS 8, Apple's quick reply feature had made it easy to respond to messages without leaving the lock screen or whatever app you're currently in, but you can't utilize all of Messages features when responding this way. You can't add photos, use iMessage apps, record audio, choose effects, or send handwritten messages. You also couldn't use Tapback, but iOS 12 just changed this.
If you're like me and you typically find yourself scrolling through Twitter before bed, you will be psyched about this new update for Android.
Uber has been in the hot seat for awhile now, for many reasons, especially for being sued by Waymo over stolen LiDAR designs. But now, perhaps the attention will be taken off both Uber and Waymo as a new contender enters the LiDAR arena; A small, independent company called Luminar has finally let the world in on what it has been cooking up.
Even the best-maintained kitchens occasionally get a fruit fly infestation. These critters descend, lay eggs (up to 500 at a time!), and then disappear usually only after extreme cleaning efforts (i.e., finally attacking that weird puddle of goo behind your refrigerator).
With warm weather comes bugs, and with bugs come bites, and with bites come itches. From ticks and spiders to mosquitoes and bees, insect bites come in sundry shapes and sizes, but they all commonly pull an itchy, red reaction out of our bodies.
To get the Guerilla Tactics achievement / trophy in Bulletstorm, you must execute 25 skillshots in a single Echoes map. Skillshots are the most fun part Bulletstorm. This video will give you a handy step-by-step guide to getting the achievement in Collapsed Building.
If you prefer glow sticks over candles during a power outage, then this how-to is for you! Although glow sticks are used as temporary light sources, there are other applications for them. Divers use them for night diving, fisherman use them to catch swordfish, and the military uses them for light markers, along with infrared versions used in conjunction with night vision devices. But with all these handy uses for glow sticks, the most popular is — recreational use, like dancing at raves, some...
Andy Field shows us a trick that has little set up and carries a high reaction. This trick is called the wrong prediction trick. You will need a deck of playing cards a wallet and a black magic marker. Take out the queen of hearts and write "9 of clubs" on the back of it. Stick the card in the wallet face side up this will be called the "force card". Find the 9 of clubs in the deck and slightly bend it to give a slight concave effect. Do the same to the queen of hearts. Fan out the deck face ...
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.
What is MnSO4 and MNO2, anyway? They are they molecular formula for Manganese Sulfate and Manganese Dioxide. And you can make one from the other. But how?
Hot ice is a very cool experiment. This is a recipe for homemade 'hot ice' that mimicks the sodium acetate one but only requires simple ingredients!

There may be questions from some about the future of Magic Leap, but in Japan, The Force is with the augmented reality startup.
On May 25th, 1977 a small movie with a $13,000,000 budget came out. At the time, the executives involved had no faith that this film would make any money. To the surprise of many in the industry, not only did that film set records, it led to a number of other movies, video games, books, toys, cartoons and so much more. This film we know as Star Wars became a long lasting hit that is still setting records 40 years later.
In 4.74 seconds, I can barely bend over to tie my shoes, and somehow this guy managed to crush the human world record for solving the Rubik's Cube in that time exactly.
I loved the original Star Wars trilogy when I was a kid, but loathe all of the current DVD, Blu-ray, and streaming versions available today. Ever since 1997, every version of A New Hope, The Empire Strikes Back, and Return of the Jedi has had horrendous CGI effects added in that George Lucas deemed necessary to bring his "ideal" version to life.
A long time ago in a galaxy far, far away, a man by the name of George Lucas wrote an amazing trilogy about a new world and the power of the Force… and then subsequently ruined the franchise 22 years after the original release date.
Biting into a perfectly ripe mango is living proof of nature's goodness. The flesh is at once creamy, smooth, tart, and sweet. Plus they're incredibly good for you.
If you have a limited or restricted data plan, monitoring your usage can be the difference between escaping the month without overage fees or emptying out your wallet.
This video shows how scientists use creativity to measure non-obvious things like reaction time, lung capacity and jump height.
