The history of paperclips
Paperclips are often seen as simple and mundane office supplies, but their history is actually quite fascinating. The first patent for a bent wire paperclip was filed in 1867 by Samuel B. Fay, but it wasn’t until the early 20th century that they became widely used.
In the United States, the Gem Paper Clip Company began producing and distributing paperclips in 1892. They quickly gained popularity due to their low cost and convenience. During World War II, paperclip production skyrocketed as they were used to bind important documents together.
There have been many variations of the paperclip over the years, including different shapes and materials such as plastic and even gold. However, despite these changes, the basic design has remained largely unchanged for over a century.
The science of sneezing
Sneezing is a natural reflex that helps our bodies expel irritants from our nasal passages. When we inhale something irritating like dust or pollen, nerve signals are sent to our brain which triggers a series of actions resulting in a forceful expulsion of air through our nose and mouth.
Interestingly enough, scientists have found that sneezes can travel up to 100 miles per hour! This means that when you sneeze without covering your mouth or nose with your elbow or tissue you could be expelling droplets containing germs into the air around you.
Sneezing can also be caused by other factors such as allergies or infections like colds or flu viruses. While it may seem harmless on its own, frequent sneezing can be indicative of an underlying health issue that should be addressed by a medical professional.
The art of whistling
Whistling is one form of human communication that has been used for centuries across cultures all around the world. It’s often associated with happiness and being carefree; however there are also more practical uses for whistling such as signaling or calling attention.
When we whistle, we create sound by directing air through a small opening in our lips or between our teeth. The pitch of the whistle is determined by the shape and size of this opening as well as the force and speed of the air being expelled.
While many people can whistle naturally, others may need to practice and develop their skills over time. There are even competitions held around the world where individuals showcase their unique whistling abilities!
