6 Common Mysteries with Answers: Top Surprising Facts You Need to Know

The world around us is filled with countless everyday mysteries. Some are so common that we’ve come to accept them without question. But have you ever wondered about the reasons behind these peculiar occurrences? In this article, we’re going to look into six such common mysteries and provide you with answers that will satisfy your curiosity.

1. Why Doesn’t Glue Stick Inside the Bottle?

You may have noticed that the glue you use at home or in the office doesn’t harden inside the bottle, even after prolonged storage. The answer to this intriguing phenomenon lies in the presence of air. Glue, especially liquid glue, needs moisture to cure and harden. When you close the glue bottle, it traps a small amount of air inside. This prevents the glue from drying out. As a result, you can use it for multiple applications without worrying about it hardening within the container.

2. Why Is “Ambulance” Written Backward?

One common sight on the road is an ambulance with its name written backward. This might appear unusual at first, but there’s a crucial reason behind it. When you see an ambulance in your rearview mirror, the mirrored writing makes it appear correctly. In emergency situations, every second counts, and this design ensures that drivers in front of the ambulance can quickly identify it as an emergency vehicle, even when viewed in their rearview mirrors.

3. Can You Sneeze with Your Eyes Open?

Have you ever heard the advice that it’s impossible to sneeze with your eyes open? While it’s not entirely impossible, it’s challenging for most people to sneeze with their eyes open. The body’s natural reflex during a sneeze is to close your eyes as a protective measure. Sudden and forceful sneezes can expel germs and debris, and by shutting your eyes, your body minimizes the risk of damage or irritation.

4. The Puzzling Hole in the Cap of a Ballpoint Pen

Ballpoint pens typically have a small hole in the cap. This feature serves a vital purpose. In case a child or someone accidentally swallows the cap, the hole allows for airflow. Without this hole, the cap could create a vacuum in the throat, potentially leading to choking hazards.

5. Why Are Car Turn Signals Orange?

You’ve probably noticed that car turn signals are almost universally orange. The reason behind this choice of color is straightforward: it’s highly visible. Amber light is easy to spot even in bright sunlight, and it’s less likely to be confused with other colors. This clarity and visibility are essential for road safety, as it ensures that other drivers can quickly recognize a turn signal’s intent.

6. The Mysterious Line on Solo Red Party Cups

Solo red party cups are a staple at gatherings, but have you ever wondered about the small, horizontal lines near the bottom? These lines aren’t just for decoration; they serve as measurement indicators. They help you pour precise amounts of liquid for various drink recipes. For example, the first line often represents one ounce, while the second may be the two-ounce mark, simplifying the process of mixing your favorite beverages.

The Bottom Line
