Or, you know, just do what everyone else does and fetch the tequila…
What’s better than watching two massive tesla coils discharging big sexy bolts of energy into the air? Having the resultant zapping sound form the basis to the tune from Star Wars’ Imperial March! Darth Vader, eat your heart out!

If you’ve been on the fence with regards to your opinion of rap, be prepared to forever hate the genre. Rapper B.o.B. of “Airplanes” fame actually believes the world is flat and that we’ve all been lied to and deceived, in his very words. It started on January 24th, when B.o.B. posted the following tweet…
He followed up this grievously stupid Tweet with the following drivel:
“I’m going up against the greatest liars in history.”
“You’ve been tremendously deceived.”
Okay. WHAT?? I didn’t know people still believed the world was flat and the fact that more than 2,000 people LIKED his Tweet is seriously concerning! Unfortunately, today’s society is more influenced by people like rappers than they are by scientists, so our children (and the simple-minded) are at a real risk of buying into this prehistoric notion.
Enter the coolest guy alive: astrophysicist and curator of the Hayden Planetarium, Neil deGrasse Tyson. In this video, Neil presents the facts in pure poetry, calling B.o.B. out for the simple fool he is – but, you know, in a totally intellectual and non-offensive way. So if you were feeling a little slow today and struggling to get your brain into gear, take solace in the fact that there are people out there who are far more ignorant than you are. It just sucks that many of them are millionaires *coughdonaldtrumpcough*
If you’ve ever made popcorn on the stove in a pot with a glass lid, you’ve probably tried your darndest to see what actually happens when the corn kernels explode. How does something so hard and inedible become something so fluffy and delicious? And even if you can get a good enough look without having your eyeballs seared by hot oil, nothing can beat witnessing corn popping in super slow motion.
So here you go! (You’re welcome)

Colonel Chris Hadfield is pretty much the modern face of space exploration. In this video and others that have been uploaded to YouTube, he demonstrates the awesomeness of zero gravity and the various peculiars of space living, answering age-old questions asked by children everywhere: How do you sleep in space? How do you wash your hands? What food do you eat?

It can be said without a doubt that bringing a bird with you on your safari makes it way more awesome. Especially if said bird looks tight in a bikini. You can share in the joy of spotting that elusive leopard, watching cheetah chase ill-fated gazelle across the savannah and being stranded in a herd of elephant; desperately hoping that amorous-looking bull doesn’t take a fancy to your Jeep. But I’m not talking about THAT kind of bird. Birds, the feathered variety, are awesome. And the next time you drive home from Magaliesberg feeling short-changed because you didn’t see any lions AGAIN, perhaps you’d better start thinking about becoming a twitcher.
Bird-watching: A Definition
I’ve harboured a deep interest in birds since I can remember. Some people are addicted to nicotine, amphetamines or Robert Pattinson. I love bird watching. I really do. And I’m pretty sure that, psychologically, it has something to do with a love of collecting meaningful things. Every time my family would go for a weekend, week’s or month’s vacation somewhere in southern Africa, I would make and keep a list of the different species of birds we identified during the course of that holiday.
You experienced a shudder of awe and excitement when you saw a lion on your African adventure. I experienced a shudder of awe and excitement when I saw a Violet-eared Waxbill at the Karoo National Park. Partly because, against the drab semi-arid landscape, it is one of the most beautifully coloured creatures you could ever imagine; something straight out of Lewis Carroll’s Alice in Wonderland. And partly because this particular species of waxbill didn’t appear on the Karoo National Park’s bird list, meaning that we were the first to report seeing it there. Essentially, we made history.
I See Your Lion and Raise You a Bataleur Eagle
I experienced another shudder of awe and excitement when I saw a Drakensberg Prinia in Pilgrim’s Rest; a Pallid Harrier at the Blyde River Canyon; a Collared Sunbird at the Nelspruit Botanical Gardens; a Striped Cuckoo at the Pilansberg Nature Reserve outside Rustenberg and again when I saw a flock of Southern Bald Ibises in the Drakensberg. None of these are particularly striking birds – except perhaps the Bald Ibis, whose head resembles an unmentionable male body part. But they were all new! I had never seen them before! It’s like discovering the Mufasa marble in your Engen Garage lucky packet back in the day when the Lion King and marbles were all the rage.
For the record, the Lion King was, is and always will be awesome.
Identifying a brand new bird and ticking it off in your book may sound completely nerdy, inane and lame. But it actually makes you feel amazing; like you’ve accomplished something. It’s a tiny intellectual victory and one of those ingredients that makes life rich and exciting.
I saw a brand new species of bird!
You saw a lion.
I saw a Crowned Eagle!
You saw another lion.
I saw a Giant Eagle Owl!
You saw (oh wow!) another lion.
I saw a Carmine Bee-eater.
You saw (surprise) a lion!
For every one species of awesome animal you see on safari. I see 10, maybe 20 different species of birds. This is no war, my friends. No competition. The point I’m trying to make here is that if you can culture and develop an appreciation and then a love of identifying birds, you can get so much more out of any holiday, any getaway and any safari experience. You’ll also totally impress your chick who, through your appreciation of soft feathered creatures, will see your softer and more vulnerable side.
And then you’ll get to show her your softer and more vulnerable body parts.
Kgalagadi Case Study, August to September 2009
Many years ago, I went on a 10-day vacation to the Kgalagadi Transfrontier Park, which straddles the three borders of Namibia, Botswana and the Northern Cape. The bird list I had kept for that holiday totalled 106 different species. The animal list I made totalled 12. Actually, it was more like 11. Animal #12, which we thought was a leopard prowling around the camp at night, turned out to be nothing more than my mother’s snoring. Or so we suspected after three consecutive nights of rhythmic zzzggghhhnnnnngggg, zzzggghhhnnnnngggg, zzzggghhhnnnnngggg-ing, which is actually quite similar to a leopard’s cough-like grunting.
We saw ONE lion that entire holiday. And it was a female so pregnant with zebra meat that she had hitched a leg up onto the bole of the acacia tree she was food coma-ing under in order to make more space for her distended gut. She didn’t so much as bat an eyelid at the rocks we were throwing at her to get her to move.
I am, of course, just kidding.
On that same trip, we spotted a beautiful Giant Eagle Owl in her nest in broad daylight; identified the tiny Pygmy Falcon killing machine; heard the haunting yelps of Pearl-Spotted Owls at night and kept the campsite company of the flamboyantly coloured Burchell’s starling.
Class Dismissed: The Take-Home Message
I have always kept bird lists for the various holidays our family has been on. I also keep a list of animals on the occasions we go to wildlife reserves. Every single time, my list of different bird species, which has often stretched into the hundreds, dwarfs the list of different animal species. Nothing can be more exciting than actually spotting a leopard in a tree, seeing cheetah in action or watching a hippo emerge from the water (or doing that funny tail-thing when they poop.) But to go on safari and never notice the activity constantly going on around you, in the bushes, in the trees, on the ground, in the sky… well you are cheating yourself out of 90% of the fees you paid at the park entrance.
Open your eyes friends.
And whatever you do. Never, ever sit under a hornbill perched in a tree. They have impeccable aim.
The most frustrating thing about the “ghost videos” and “real ghost footage” you find on the Internet is that they could so easily be the work of any amateur film student. How do you know what you’re seeing is real and that you aren’t being duped? Some of these videos are quite obviously terrible, staged or easily explained, while others seem to capture something truly paranormal going on. A few of the clips in the following ghost video compilation had my hair standing on end and I’m a skeptic… whether the footage is real or cleverly manipulated, we’ll never know!

In the Free State of South Africa, 2012 was a year marked by an outbreak of severe thunderstorms. This province lies quite far inland of the subcontinent, to the northeast of Cape Town and to the west of the Drakensberg; the magnificent mountain chain that borders the eastern coastline of South Africa. These severe thunderstorms caused quite a bit of grief for the inhabitants of the Free State, levelling 55 houses and hospitalising 5 people, according to All Africa online publication. But in addition to the heavy rains, lightning and wind damage, these thunderstorms had the ill-grace to drop a couple of tornadoes too!
To put things into perspective, South Africa is not a country known for tornadoes. If you’re thinking of tornadoes, your imaginative context is probably located in the aptly named ‘Tornado Alley’ in the mid-western states of America. Now, as someone who has a degree in atmospheric science, you can imagine how many questions I was fielding from people who had heard about the severe weather events I just mentioned. Not questions as such: statements rather. People rarely ask me questions about the weather. I think they’re afraid of the answers. I can handle that… but what I couldn’t handle was the fact that people were confusing hurricanes with tornadoes!
“Did you hear about the hurricanes in the Free State?”
To anyone in atmospheric, Earth, ocean or any related sciences – regardless of your specialization – confusing tornadoes with hurricanes is like confusing your grandmother with Megan Fox. It’s like confusing an elephant with a pineapple. The concept of a hurricane tearing across the Free State is about as alien to the weather educated as a giraffe cavorting around the North Pole. Wearing snow shoes.
But, before you cringe at the memory of you making this rather Herculean error, one must take into account that the majority of you out there aren’t weather educated. That’s perfectly all right! We’re going to change that right now. Hurricanes and tornadoes: what’s the difference? Moreover, what’s the big deal if you get them confused? Well, when it comes to these two somewhat (ok, VERY) tempestuous weather phenomena, size really, really, REALLY…
… really, REALLY, really, REALLY, REEEEEEEEALLY does count.
Hurricanes: Kicking Ass and Taking Names
Satellites captured this fairly terrifying image of Hurricane Fran hurtling towards North Carolina on the 5th September 1996. “Fran” caused so much trouble that they decided to NEVER call another hurricane “Fran” again.
FYI, hurricanes are named alphabetically according to their order of development during the hurricane season. The first to appear will be named something beginning with an ‘A’, the second ‘B’ and so on and so forth. Hurricane Fran was therefore the 6th fully fledged tropical cyclone to develop that season and one whose limelight was solidly claimed in 2005 by Katrina and again in 2012 by Sandy. Those bitches!
Hurricanes are large tropical storms born over the equator. Fed by prodigious updrafts of hot, moist, sexy air, these giant swirling monsters generate, via condensation alone, 200 times the electrical generating capacity of the entire freaking planet, according to the Atlantic Oceanographic and Meteorological Laboratory. For those of you who like numbers or are easily impressed by them, this equates to 600,000,000,000,000 Watts. This is not even to mention the amount of energy generated by hurricane winds, which is an additional 1,500,000,000,000 Watts of unbridled weather rage!
I don’t even know what that number is… a billion million? A trillion zillion billon million?
Ooh! Aah! Hurricane Statistics
- Damage: Should they make landfall, hurricanes can cause tens of billions of dollars’ worth of damage. Katrina was only a category 3 storm when it had its fender-bender with the Mississippi Gulf Coast. And yet its damage was estimated at $81,000,000,000!
- Storm Diameter: Hurricanes are huge systems with an average diameter of 800 km (500 mi), although Hurricane Carla, which raged into the Texas coast in 1961, was an especially big girl at 1280 km (800 mi) across.
- Wind speeds: Hurricanes are wrathful systems with category 5 storms (you do not get larger) generating winds of over 250 km/hr or 156 mi/hr.
- Associated Severe Weather: Hurricanes are social creatures. They have loads of friends they like to bring to the party they tend to gatecrash. These include torrential rainfall, thunderstorms, lightning, hail and storm surges, which is an increase in average sea level that can be in excess of 5 meters or 19 feet! To add insult to grave injury, hurricanes can even generate tornadoes.
- Weakness: For all their size, energy and capacity for total annihilation, these tropical super storms cannot survive over land. They require a tireless volume of hot, moist air – as is found over the equatorial oceanic regions – in order to preserve storm motion and momentum. That dry continental air just won’t do. Plus, all the friction and turbulence caused by onshore topography (mountains and such) tend to break up the party pretty quickly.
“Actually I think that was the same one”
– ‘Twister’, 1996
I regard tornadoes the same way a sadomasochist regards nipple clamps: they’re deliciously terrifying. Having said this, my opinion is fantastically unfounded because I have never, ever witnessed or had my house relocated by a tornado. If I had, I would probably drop the enthusiasm a notch.
A Kansas tornado tears across a country roooooad, take me hooooome.
A tornado is a raging column of rotating air that extends from the ground to the base of its parent cumulonimbus cloud, “Cumulonimbus” being the longest and fanciest word everyone remembers from High school geography. I know this because every time I tell someone I have a background in weather, they say, “Oh! So you, like, studied cumulonimbus clouds!”
Yeah, something like that buddy.
Tornadoes are generated by severe thunderstorms in atmospheric environments full of wind shear and abundant lower level moisture, amongst other ingredients. Next time you’re in the bath or swimming pool, make your hand flat, put it in the water and paddle. You’ll notice tiny little vortices or whirlpools that spin off in either direction.
“Wind shear” really just refers to two masses of air moving at different speeds and/or different directions to each other. And, just like your hand in the pool, shear in the atmosphere generates the same kind of ‘whirlpools’ in the air, although you can’t see them because air is invisible. What happens next in tornado genesis is a powerful updraft of air, which pushes these horizontal columns of rotating air vertical. And this is when shit starts getting real.
A gorgeous supercell thunderstorm at sunset. This cloud formation, known as a “mesocyclone” to academics and a “mothership” to nerds, is the atmospheric platforms from which tornadoes are commonly spawned.
Ooh! Aah! Tornado Statistics
- Damage: It just takes one tornado straying into a heavily built up area to rack up damage totals that would bankrupt an entire country. In May of 2011, a single tornado tore through Joplin in Missouri – a city of 50,000 inhabitants. The reports that emerged at the time estimated the damage of insured property alone to be in the region of $3,000,000,000 (billion), and all from a single tornado. This doesn’t even take into account the uninsured losses suffered.
On the brighter side – Tornado, 1: Insurance companies, 0.
- Wind Speeds: Tornadoes are violent creatures. The wind speeds that tear around the funnel, more specifically, of F5 tornadoes, have been clocked in at over 500 km/hr or 315 mi/hr. This is more than half the cruising speed of a commercial airliner.
- Associated Severe Weather: Like hurricanes, tornadoes are social. You will generally find them hanging out with lightning, torrential rain, giant hailstones, wind (duh) and the occasional cow or 18-wheeler semi-trailer.
- Lifespan: For all their fury, tornadoes are relatively short-lived with the longest ‘twister’ on record having raged on for 3.5 hours. This suspected F5 tornado, dubbed the Tri-State Tornado, tore through 350 km (220 mi) of Illinois, Missouri and Indiana on the 18th March in 1925, leaving almost 700 people dead in its wake.
While hurricanes may boast more impressive size statistics than a single tornado, one should note that the kinds of thunderstorms that generate tornadoes are rarely isolated and often travel in waves with one thunderstorm cell feeding the formation of several others. In 2011, in fact, the National Severe Storm Laboratory recorded the most prolific outbreak of tornadoes in American history! Between April 25th and April 28th 2011, a staggering 358 tornadoes were recorded, with the majority of them having touched down within a single 24-hour period. Thanks to a much more sophisticated weather forecasting and tornado warning system, this outbreak caused half the death toll as the single Tri-state Tornado of 1925.
Class Dismissed: Your Take-Home Message
There are many big and important differences between hurricanes and tornadoes, most of which are related to scale: scale in size, in wind speeds, in damage done and in lifespan. Hurricanes are huge weather systems that last days and can cause widespread destruction. Tornadoes are much, much smaller weather phenomena generated by severe thunderstorms. Yet, in spite of their exponentially smaller size and shorter life spans, they can do incredible localized damage and frequently boast wind speeds greater than even a Category 5 hurricane.
So, to sum it all up and pack it in a nutshell:
Tornadoes can rearrange your back garden and perhaps relocate your house.
Hurricanes can rearrange your province and perhaps the entire eastern coastline of your country.
It’s too bad that seawater is salty, because with a bit of sweet flavouring, everyone would have had access to unlimited slushy “Slurpee” a year ago, courtesy of Mother Nature!
Video Source: “Giant Frozen Waves Nantucket Beach” Uploaded by Galaxy 11
The United States spent much of February of last year in the frigid grips of a record-breaking icy winter. Yet, in addition to the usual suspects, which include deep snow and biting winds, the cold would seem to have even won over the briny seawater of the north Atlantic Ocean. This video shows a series of images of ocean waves breaking on the shores of Nantucket in New England (northeast USA), only, there seems to be something distinctly different about these waves!
The photographer, Jonathan Nimerfroh, is an avid surfing enthusiast and on a trip to the beach, he noticed something odd about the horizon. As it turns out, the temperatures are so low in the area the water has begun to freeze and so, what we are looking at are giant slushy waves! These icy waves have also been aptly called “Slurpee waves”
The maximum temperature on the day these pictures were taken was at a teeth-chattering -7 degrees celsius (17 degrees Fahrenheit).
What’s truly amazing about this is that salt is known to lower the freezing point of water to well below zero degrees celsius. This is precisely why we throw salt over our driveways to prevent them from icing up. The fact that even the salty seawater in northeast United States began to freeze is testament to the uncharacteristically cold winter they had last year.
