Why Does a Laptop Need Its Own Bin at Airport Security?

Taking your laptop out of your bag is the second most annoying thing travelers have to do at airport security (number one, of course, is being forced to remove your shoes and put your bare feet on the undoubtedly filthy floor). Some electronic gadgets, like e-readers and tablets, can go through the scanner with your bag. Why does your laptop have to go through in its very own bin?

Your laptop, along with other large electronics like gaming systems and DVD players, are complicated machines. According to Bob Burns on the TSA blog, “Larger laptops and game consoles appear more dense and need to be removed in order for the X-ray operator to get a good look at [what’s in] your bag.” (Generally, e-readers and tablets can stay in your bag, unless they’re keeping the agents from seeing what else is in your carry-on.)

Putting your laptop or gaming system in its own bin also allows TSA agents to get an unobstructed view of the machine—the better to examine it more closely (and quickly—they take about 3 seconds to check each bin). “The larger the laptop, the more stuff you can hide in it,” Burns says on the blog. “Items have been found concealed in laptops in the past, so we have to be able to get a good look at them.” And not just laptops: TSA agents have caught passengers concealing gun magazines in DVD players, inert grenades, guns in hollowed out books, stun guns disguised as smartphones, sword canes, and marijuana hidden in jars of peanut butter (which, presumably, was to be a snack).

Big Questions
What Are Curlers Yelling About?

Curling is a sport that prides itself on civility—in fact, one of its key tenets is known as the “Spirit of Curling,” a term that illustrates the respect that the athletes have for both their own teammates and their opponents. But if you’re one of the millions of people who get absorbed by the sport once every four years, you probably noticed one quirk that is decidedly uncivilized: the yelling.

Watch any curling match and you’ll hear skips—or captains—on both sides barking and shouting as the 42-pound stone rumbles down the ice. This isn’t trash talk; it’s strategy. And, of course, curlers have their own jargon, so while their screams won’t make a whole lot of sense to the uninitiated, they could decide whether or not a team will have a spot on the podium once these Olympics are over.

For instance, when you hear a skip shouting “Whoa!” it means he or she needs their teammates to stop sweeping. Shouting “Hard!” means the others need to start sweeping faster. If that’s still not getting the job done, yelling “Hurry hard!” will likely drive the point home: pick up the intensity and sweep with downward pressure. A "Clean!" yell means put a brush on the ice but apply no pressure. This will clear the ice so the stone can glide more easily.

There's no regulation for the shouts, though—curler Erika Brown says she shouts “Right off!” and “Whoa!” to get her teammates to stop sweeping. And when it's time for the team to start sweeping, you might hear "Yes!" or "Sweep!" or "Get on it!" The actual terminology isn't as important as how the phrase is shouted. Curling is a sport predicated on feel, and it’s often the volume and urgency in the skip’s voice (and what shade of red they’re turning) that’s the most important aspect of the shouting.

If you need any more reason to make curling your favorite winter sport, once all that yelling is over and a winner is declared, it's not uncommon for both teams to go out for a round of drinks afterwards (with the winners picking up the tab, obviously). Find out how you can pick up a brush and learn the ins and outs of curling with our beginner's guide.

Why You Should Never Take Your Shoes Off On an Airplane

What should be worn during takeoff?

Tony Luna:

If you are a frequent flyer, you may often notice that some passengers like to kick off their shoes the moment they've settled down into their seats.

As an ex-flight attendant, I'm here to tell you that it is a dangerous thing to do. Why?

Besides stinking up the whole cabin, footwear is essential during an airplane emergency, even though it is not part of the flight safety information.

During an emergency, all sorts of debris and unpleasant ground surfaces will block your way toward the exit, as well as outside the aircraft. If your feet aren't properly covered, you'll have a hard time making your way to safety.

Imagine destroying your bare feet as you run down the aisle covered with broken glass, fires, and metal shards. Kind of like John McClane in Die Hard, but worse. Ouch!

A mere couple of seconds delay during an emergency evacuation can be a matter of life and death, especially in an enclosed environment. Not to mention the entire aircraft will likely be engulfed in panic and chaos.

So, the next time you go on a plane trip, please keep your shoes on during takeoff, even if it is uncomfortable.

You can slip on a pair of bathroom slippers if you really need to let your toes breathe. They're pretty useless in a real emergency evacuation, but at least they're better than going barefoot.
