As a boy, I spent most of my formative years playing with action figures and reading comic books. Nonetheless, I also got to play house with my female cousins when they wanted to. Who says you have to be a girl to play house, anyway? We would use plastic toys, paper, and sometimes real cutlery…

igloo design

You have probably seen an igloo before (even just on videos) and wondered just how in the world some frozen water can keep a person warm. I mean, it’s made out of ice! But according to Joe Hanson of It’s Okay To Be Smart, there are specific reasons that can explain the igloo’s ability to…

climbing wind turbine

Have you ever seen a wind turbine and wondered how in the world people keep them in good condition? Well, simple: they climb the dang things. https://www.youtube.com/watch?v=UWSckm8zTc8&ab_channel=TomScott A few months ago, Tom Scott climbed one of Octopus Energy’s wind turbines in the UK. This wasn’t a luxury trip, however. After climbing the 50-meter tall ladder…

Forget science t-shirts and obscure math formula tattoos; there is now a more fashionable way to get your geek on. Upcycling old circuit boards, the folks at Circuit Breaker Labs handcraft unique pieces of jewelry that show the miniature beauty of a PCB. If you ever take the time to look closely at a circuit board,…

Owning a pet means a boatload of responsibilities. This is why getting a short break from all those tasks (or at least making them easier to manage) feels like a huge relief. We already saw it with the auto-filling litterbox on Kickstarter. Nonetheless, our pet’s doo-doo isn’t the only thing we need to mind when…

bank notes invisible ink

You might not notice it because of how fast it leaves your hands, but paper bills have some neat tricks up their sleeves. Everyone knows about serial numbers and security ribbons, but did you know certain national banknotes (US Dollars included) have a layer of invisible ink that makes them even harder to counterfeit? That’s…

It’s amazing that even with so many multi-tools on the market, very few of them have the one thing most people need: a writing apparatus. I mean, what good is a mini-ruler/blade/tape measure when you don’t have any marking tool to use with them? With this, the folks at World’s Tiniest have decided to make…

printer scam

I’m happy we live in a prevalent digital age. Things are pretty instant now to the point that you don’t need to move a muscle just to have a specific task done. Need to sweep the floor? There’s the Roomba. Need breakfast ready when you wake up? There are self-timer kitchen appliances. So, how come…

magnapot

Most desk jobs nowadays involve staying indoors in front of a computer screen. While this is fine for introverts and shut-ins, it doesn’t bode well for those who long for the great outdoors. So why not bring a small and manageable piece to your workspace? https://www.youtube.com/watch?v=BB1t82WmC-s&ab_channel=Amazing Magnapot is a series of modular ceramic pots which…

flagship light

There’s just something about the smokey, outdoorsy smell and flavor of well-grilled foods that get me. But as summer ends and the weird weather approaches, chances to cook on an outdoor grill become few and far between. So instead of hoping for good weather, why not bring the grill inside your home? https://www.youtube.com/watch?v=NLpjpgpzwWw&ab_channel=THE3BEST Flagship Light…

car window experiments

When I was four, I had that stupid idea of stopping the blades of an electric fan… using my tiny fingers. Really just a child curious about things. Long story short, I wasn’t able to point at things for a while. But, the good news is I still have that finger (in case you were…

mark rober dominator

Mark Rober, a former NASA and Apple engineer, always has something up his sleeve. This time, his newest project is a domino-stacking robot he nicknamed “Dom” (short for “Dominator”). https://www.youtube.com/watch?v=8HEfIJlcFbs&t=130s&ab_channel=MarkRober As said, Dom has one specific function: to stack as many dominoes as fast and as accurately as possible without a single misplaced piece. Why,…

human centrifuge

Even with the human body’s natural ability to adapt, we aren’t exactly made to withstand too much g-force. You can chalk this up to humans’ inability to fly or run at supersonic speeds. So, why do some folks even bother going to high-G training? Well, it’s to up their g-tolerance before getting in an aircraft.…

minecraft wooden pickaxe irl

Ask anyone who has played Minecraft for 5 minutes and they’ll tell you how things start off. You are dropped into a random world, then punch some trees to get wood, and you make yourself some wooden tools on a workbench. Well, the question is: can a wooden pickaxe break anything in reality? https://www.youtube.com/watch?v=cEz_2spRbek&ab_channel=LouisWeisz To…

underground bunker with spoons

You can deny it all you want but at some point in your life, you probably thought of digging a hole to (or through) the center of the Earth. There are those western folks who even believe that with enough hard work and dedication at digging a hole, they could pave the way for the…

Vegan shoes (those that are made without involving any animal in the process) are rapidly making themselves known in the footwear industry. Instead of harming animals, these supposedly Earth-friendly pieces of footwear rely on faux leathers which are made from PVC or polyurethane. This gives them that leather-like feel. However, what you might not know…

wooden axe out of tree stump

After carving a wooden spoon using a spoon, you would think craftsman Alex Apollonov wouldn’t have any more inception-like tricks up his apron. Well, you would be sorely mistaken for thinking so. Upon discovering a stray tree stump in his backyard, Apollonov decided that the best way to get rid of the said tree would…

Owning pets is like having 5-year-old children around you 24/7. While their Instagram photos and videos paint a picture of a perfect world, life behind the scenes is anything but. You have to train them, feed them, and worst of all… clean up their mess, specifically their dung! No one likes to clean someone (or…

chainless drive shaft

While most people are familiar with the classic chain gears in bicycles, there are a number of other, less greasy alternatives now which are seeing more widespread use. One of these alternatives – the chainless shaft drive – hasn’t quite found a foothold in the bicycle world. But why is that? https://www.youtube.com/watch?v=eimLIkJaNFM&ab_channel=CYCLINGABOUT In a video…

Though I don’t wear a pair of glasses regularly, I know how annoying it can be to have dirty sunglasses at the beach. It’s hard to enjoy the scenery when someone’s fingerprints (most likely yours) are smudging up the view. You could wipe your glasses yourself, but that might just make things worse. So, why…

chainsaw damascus experiment

Metalworks require a lot of time, patience, and hard work. Moreover, the materials for metalworking aren’t cheap or easy to come by, so it’s always nice to see some old chunks of metal get recycled into something new. https://www.youtube.com/watch?v=-846gmAeNU8&t=648s&ab_channel=BlackBeardProjects Italian metalworker Black Beard Projects thought it would be a good idea to break down a…

potholes

You hate them. We hate them. They’re the bane of every vehicle owner – potholes! These nasty depressions in the roads may seem harmless to pedestrians, but they can cause millions, if not billions, of dollars in vehicular damage if left unchecked. But how do these sneaky buggers even come to be? https://www.youtube.com/watch?v=gRuarpWsKHY&t=478s&ab_channel=PracticalEngineering Civil engineer…

road barrier safety design

Unless you’ve been in a vehicular accident (which I hope you haven’t), you won’t notice how much road barriers have evolved over the years. Despite what you see on television, these accident prevention materials have actually gotten better at saving lives rather than ending them. It just so happens that the small percentage of deaths…

18th century ammunition

Back in the 18th century, travelers on the American frontier had to constantly move to get stuff done. Whether it’s to trade, settle, or explore, chances are you’d need a gun to feed and protect yourself. Be it a musket or a pistol, guns back in the day used circular bullets mixed with gunpowder to…

nerf gun cinematography

This is one of those instances where art begets art. Inspired by the high-octane movie John Wick: Chapter 2, the guys at Corridor decided to put their own spin on the mass-murdering hitman… only with a more kid-friendly arsenal. Meet Nerf John Wick: https://www.youtube.com/watch?v=9MrnAJsxL8c&ab_channel=Corridor The 3-minute video showcases moves lifted directly from the film, such…

paper mache covid-19 virus

As we near the end of this pandemic and things start going back to normal, there are few things I’m definitely going to miss. I’ll miss staying indoors for weeks and weeks. I’ll miss not caring about how I look as no one but my immediate family gets to see me. But most of all,…

miniature hydroelectric dam

Normally when you water your plants, you sprinkle them using a garden hose or some kind of water container. That’s for sure… unless you have the time and the vigor to create a hydroelectric dam to make this task more automatic. That’s exactly what the YouTuber known as Construction General did. https://www.youtube.com/watch?v=jzG804zrDmQ By scaling down…

3d print with glue gun

If you break it down to the basics, 3D printing simply involves heating filament and using a bunch of preprogrammed electronics to place it where you want. So, in theory, you can cut out all the complexities by heating the filament and manually spreading it yourself… right? https://www.youtube.com/watch?v=6aJDnpeFHaY While 3D printing pens definitely exist, the…
