The Reason Sneakers Have an Extra Set of Holes

If you examine your favorite items of clothing closely enough, you may start to ask questions like: Why are shirt buttons on different sides for men and women? (Because, historically, women didn't dress themselves.) Or why do my jeans have a tiny pocket? (To hold your pocket watch, of course.) Both of the clothing quirks mentioned above are relics of a different time, but if you look at your sneakers, you'll find a commonly-ignored detail that can be useful to your daily life.

Most sneakers have an extra set of holes above the laces that are often left empty. The holes may not line up exactly with the rest of the laces, indicating that they're there to serve a special purpose. For many situations, ignoring this pair of holes is totally fine, but if you're tying up your shoes before a rigorous run or hike, you should take advantage of them.

The video below from the company Illumiseen illustrates how to create a heel lock with these extra holes. Start by taking one lace and poking it through the hole directly above it to create a loop, and then do the same with the lace on the other side. Next, take the ends of both laces and pull them through the opposite loops. Tighten the laces by pulling them downwards rather than up. After creating the heel lock, secure it with a regular bow tie.

What this method does is tighten the opening of your shoe around your ankle, thus preventing your heel from sliding against the back of it as you run. It also stops your toe from banging against the front of your shoe. The heel lock is especially handy for long runs, walks, and other activities that often end with heel blisters and bruised toes. Even if you aren't slipping on your shoes for exercise, lacing up those extra holes can make a loose-fitting sneaker feel more comfortable.

Of course, the trick only works as long as your laces stayed tied—which even the most expertly-tied knot can't guarantee. Here's some of the science behind why your shoes often untie themselves.

The New iPhone 11 Is Triggering People With Trypophobia

People with trypophobia, or a fear of clusters of small holes, know which triggers to avoid. Soap bubbles, lotus seed pods, and the insides of cantaloupes can all induce panic and revulsion in people who are sensitive to the pattern. Now, they have a new item to add to their list. As Gizmodo points out, the new iPhone has a design feature that's turning off trypophobes.

Apple debuted the iPhone 11 at an event on September 10 ahead of its release on September 20. This latest model comes with many upgrades, including a super-powered processor and longer battery life, but the biggest change has been met with a mixed reception.

The iPhone 11 Pro has three camera lenses where there would normally be one. People who prefer Apple's sleek, minimalist style have criticized the design, while those with trypophobia have had even stronger reactions. Some scientists think the fear of clusters of holes originally developed as a survival mechanism to steer people away from infectious diseases. When someone gets nauseous at the sight of three cameras grouped on the back of a smart phone, it's because it reminds them of decaying flesh.

The iPhone likely looks the way it does today thanks to another highly specific fear that afflicted Steve Jobs. The Apple founder suffered from koumpounophobia, or a fear of buttons—an incredibly rare phobia that's only been documented once in all of psychiatric literature. His fear may have lead to the popularization of the smooth, buttonless touch screen. It also explains why the tech giant preferred black turtlenecks to button-down shirts.

Though similar to trypophobia, a fear of buttons and fear of clusters of circles aren't quite the same thing. So while triggering to many, the updated iPhone doesn't necessarily conflict with Jobs's original design aesthetic.

The Reason Why Ships Are Often Painted Red on the Bottom

If you’ve ever salvaged a sea vessel, you might have noticed that ship hulls are often red. If you haven’t dealt with a shipwreck—and chances are you haven’t—you may have still seen a red hull in pictures or in partial view at a shipyard. Since that portion of the ship is below the waterline, it seems strange to opt for a specific color.

The reason is tradition. And worms.

In a piece for Jalopnik, Andrew P. Collins explains that early sailing ships protected themselves against barnacles and wood-eating worms by covering their hulls in a copper or copper oxide paint that acted as a biocide. The copper gave the paint a red tint. By reducing the muck that naturally collects on the hull, ships can maintain their structural integrity and avoid being weighed down by gunk like seaweed that would reduce drag.

These days, biocides can be mixed with virtually any color of paint. But the hulls are often painted red to maintain a nautical tradition. Collins also points out that the red may help observers gauge the load of a ship’s cargo. The more weight on board, the lower in the water it will be. That's why you often see numbers positioned vertically on the side of the hull.

No matter what’s covering the hull, it’s never going to completely eliminate growth. Often, ports will prohibit ship owners from scraping hulls while docked, since ships traveling in outside waters might have picked up a non-native species of weed that could prove problematic in a new environment.
