Coming to Grips with the Impalement Arts

No one can say when people first started throwing knives, but I’m willing to bet that it was the result of boredom, desperation or an ill-thought-out dare.  How we got from there to the Wheel of Death involves a journey from Africa, through the Wild West shows and circuses of the 1800s, and finally to our own  backyards.

Knives hardly sail through the air like arrows, but throwing them is not a difficult as it might seem. So grab your weapon of choice and join me as I explain …

The Science Behind Weather Superstitions

Weather. It can destroy homes and harvests, shut down entire regions and re-sculpt coastlines in a matter of hours. It’s small wonder we tend to be a bit superstitious about the subject, or that we’re loath to let go of the received wisdom of family, friends and the Old Farmer’s Almanac.

Then again, maybe those old wives tales contain a kernel of truth. Sometimes there’s a reason to the rhyme, as I reveal in this list of …

Biohackers Take DIY Approach to Biological Future

Not terribly long ago, do-it-yourself projects were the province of shade-tree mechanics and people who kept wood lathes in their garages. They dealt with grease and iron, wood and wiring, and left anything biological to the experts.

But today, body-modifying grinders implant jury-rigged biotech via the kitchen cutting board. Elsewhere, basement biohackers collaborate to build a better biological mousetrap, while volunteers teach basic genomics in community biotech spaces. Little by little, small pockets of enterprising people are working to make the long-promised post-human, cyborg, genomic future a reality.

Throwable Fire Extinguishers: You Had Me at “Fire Grenade”

Fire is frightening and dangerous – that’s why they call it fire. So it’s a little strange that we have laws requiring us to stock canister extinguishers but not regulations requiring that we learn how, if or when to operate them. If you’re like most people, you probably don’t even know what kind of fire your extinguisher is rated for, and you likely have no idea when you last serviced or inspected the device, if ever.

Recently, a few companies have begun marketing new kinds of extinguishers, updated versions of fire grenades intended to make fighting fires as worry-free as possible. Lightweight and easy to use, they rely on the most basic of human skills: throwing. Which raises the question:

How do throwable fire extinguishers work?

Not-so-Final Destination: Landing at the Wrong Airport

Airplane landing at sunset.“Uh, ladies and gentlemen, this is the flight deck. Thank you for choosing Airborne Airways, where your destination is always up in the air. If you’ll look out your window, you’ll see…well, we’re hoping you can tell us. Anything look familiar?”

Yes, it’s preposterous, embarrassing and more than a little dangerous, but flight crews touch down at the wrong airfield or runway more often than you might think. Which raises the question: If GPS navigation can direct any idiot with a car to his or her destination, how can a trained flight crew with state-of-the-art navigation screw up so badly? In other words…

How Can a Plane Land at the Wrong Airport?
