The purpose behind those mysterious black cables on the road

If you ever see black cables stretching across the road, you had better know what it means. I had no clue… Check comments.

While on the road, chances are you have spotted the black cables on the road.

However, although they are common and perfectly safe to run over, most people don’t have a clue about their purpose.

These rubber cables, that are stretched across the road, serve the purpose of gathering data about the traffic. So how do they work? When a vehicle crosses over them, it causes pressure which is recorded and transmitted to a counting device.

This information assists transportation agencies in keeping track of traffic flow, vehicle speeds, and volume, which is essential for urban planning, road maintenance, and safety upgrades, ultimately affecting the decisions on traffic management, road expansions, and the positioning of traffic signals or speed limits.

Rubber cables are often positioned in low-visibility areas to avoid drawing attention and to minimize any interference with traffic. This approach guarantees that the collected data is as precise as possible, representing typical traffic conditions without the effects of altered driving behavior.

You’ve Been Using Nail Clippers Wrong—Here’s What That Mysterious Hole Is Really For

Most people are familiar with nail clippers—a small tool found in almost every grooming kit. These compact clippers help keep nails clean and neat, making them a simple but important part of our routine.

However, many people don’t realize that nail clippers can have other helpful uses. Today’s nail clippers often come with extras like tiny nail files or attachments to clean under the nails. This makes the clipper a useful tool for more than just trimming nails!

**Other Uses of Nail Clippers**

Nail clippers can also handle small tasks around the house, like opening hard-to-tear packaging. Their sharp edges and small size make them handy for jobs that need more precision than scissors, as noted by *Outside Magazine*.

Even though clippers are versatile, using them correctly is important for nail health. It’s best to trim nails after a shower or bath when they’re softer and less likely to crack.

Trimming nails when they’re dry can lead to breakage since dry nails are often more brittle. For those who want strong, healthy nails, keeping them hydrated helps a lot too. Applying coconut or almond oil to the nails and cuticles can strengthen them and make trimming easier.

**The Small Hole in Nail Clippers**

You might have noticed a small hole at the end of many nail clippers. It often goes unnoticed, leaving people to wonder if it’s just decorative. But this tiny hole has a useful purpose: it helps keep nail clippers from getting lost.

If you thread a keychain through this hole, you can attach the clippers to your keys, bags, or travel kits, making them easy to take anywhere. This clever little design means that nail clippers are always handy for quick fixes on the go.

Having nail clippers with you can be really helpful. Imagine dealing with a painful hangnail or a rough nail edge and having nothing to trim it—very frustrating. Keeping nail clippers attached to your keychain makes it easy to handle these situations anytime.

Overall, while the main job of a nail clipper may seem basic, its smart design and extra uses show just how helpful it can be.

From taking care of nails to helping with small tasks around the house, this everyday tool proves useful again and again.
