How To: Snapchat Increases Its Security Push, Adds Image Captcha Feature

Snapchat has had more than its fair share of security failures and mishaps. The photo-sharing company is looking to better address some of these security gaps by adding new features, and today its most recent addition is live: the Captcha. New users will be asked to verify their "humanness" by selecting the infamous Snapchat ghost out of a selection of images. The feature is supposed to help block hacker-made bots from creating fake accounts or accessing existing ones. But rather than using t...

How To: A Layer of Water Stops Guacamole from Browning

Guacamole is one of those things that tastes far better than it looks. To someone who isn't a huge fan of avocados, guacamole's texture can appear slimy, and on top of that, its chunky green appearance brings up visions of Nickelodeon-style slime. What's even worse is the browning that occurs in just a few minutes of being exposed to air, and it's even worse if there's salt in it. I love guacamole, but that brown is enough to turn off even the most enthusiastic connoisseur. Few things are mor...

PhD in Paper Craft: Make This Insanely Detailed & Anatomically Correct Human Torso—Complete with Removable Organs

If you're studying human anatomy (or have ever visited a doctor's office), you're no doubt familiar with those plastic anatomical models with removable pieces meant to teach the different parts of the body. Before those, there were illustrated pop-up books. If you need to know the difference between the latissimus dorsi and the multifidus, you're probably better off sticking with your textbook diagrams. But if you prefer a more artful approach (and have a lot of time one your hands), this pap...

How To: Convert Your HTC One into a Google Edition HTC One for an Enhanced Nexus Experience

Ditching Sense (HTC's stock Android Launcher) is a great way to breathe new stock-like life into your HTC One smartphone without rooting, but even that has its limitations. If you really want the full Google experience, albeit with some extras, CyanogenMod has always been the go-to ROM. In effect, this will give you an experience similar to the Google Nexus or the new HTC One Google Edition.

How To: Create Velvet Hearts Nails

This is a very adorable looking nail design that I tried a few days back on my valentines day list of 'nails to do' ! It worked out exactly as I had planned , though during the execution it looked as if it may not, and I was happy enough to post this design online and share it with my viewers!

How To: Make Trader Joe's Must-Have Speculoos Cookie Butter at Home

If you've never heard of cookie butter, it must be because you live in a town where there's no Trader Joe's. It was their most popular item in 2012, and when it started to become popular, the Internet promptly went nuts, posting recipe after recipe using it as an ingredient. For those of you who don't live near a Trader Joe's but still want to see what all the fuss is about, there's good news—you can make it at home—and you don't need spiced Speculoos shortcrust biscuits either!

How To: Make a Powerful PVC Air Cannon with Coaxial Piston Valve

The video featured in this article demonstrates the function and design of a powerful form of air cannon that operates using a purpose made valve that opens very rapidly. This allows for a massive amount of pressurized air to be released at once to throw a projectile many hundreds of yards. The design of the cannon also allows the barrel and the air chamber to occupy the same space, and so it is very compact and manageable which makes for an enjoyable shooting experience.

How To: Turn a Game Boy Advance into an Old-School Miniature Arcade Cabinet

No matter how advanced technology gets, there will always be room for classic video games in the hearts of nerds everywhere. Mini arcades became very popular, as they allowed users to take arcade games on the go. As Game Boys and other mobile gaming devices appeared, the mini arcade slowly disappeared. Well, believe it or not you can combine the best of both worlds! Metku user Japala wanted to make his old Game Boy Advance SP "look cool again," so he turned it into a mini arcade cabinet.

How To: Create a Light Painting Vortex Using a DIY Reusable Steel Wool Cage

There's no shortage of uses for steel wool, but the majority of them tend to be on the pyromaniacal side, like DIY fireworks. This trick by Mike Mikkelson is no different—it uses a homemade reusable "wool cage" to create a spinning vortex of light, like in the photo below. You can do this with just a piece of steel wool on a cable, but Michael wanted something he could easily reuse no matter how many shots he took, so he built a small cage to house the steel wool out of chicken wire, a small ...

How To: Make a Totally Geeky LED Pocket Watch That Tells Time in Colors

The cell phone may have replaced the pocket watch, but thanks to some clever mods and hacks, "old-fashioned" time telling is making a comeback. Smart watches that connect to your mobile device cannot only tell you what time it is, but also change the song you're listening to and let you know how many Facebook notifications are waiting for you. Frank Zhao, an electrical engineering student at the University of Waterloo, decided to do something a little different with his LED pocket watch. It h...
