In a world inundated with groundbreaking inventions and technological marvels, it’s easy to overlook the intricate histories and mysteries surrounding the mundane objects we interact with daily. Each object harbors tales that straddle the line between peculiar and profound. Let's embark on a journey to uncover fascinating secrets behind some everyday items you might never have thought twice about.
Take, for instance, the common sticky note. Originally a failed experiment, the sticky note was born out of a botched attempt to create a super-strong adhesive in the 1960s. Dr. Spencer Silver, the scientist behind the blunder, created a mildly adhesive substance instead. His colleague, Art Fry, later found a practical use for it by adding this glue to the back of bookmarks to prevent them from slipping out of his hymnbook. Thus, the sticky note came into existence, revolutionizing how we jot down reminders.
Meanwhile, let’s turn our gaze to something even more unassuming—the humble paper clip. This everyday office supply owes its patented design to Johan Vaaler, a Norwegian inventor, in 1899. While various forms existed before, Vaaler's design became iconic due to its efficiency in holding papers together without causing damage. Despite its simplicity, it’s estimated that people around the world use around 11 billion paper clips annually. Astonishing for such a little tool!
Ever wondered why manhole covers are round? The practical reasoning is fairly straightforward: a round cover cannot fall through its circular opening, no matter how it’s placed. Furthermore, their shape allows them to be easily moved by rolling. This seemingly simple design choice contributes to safety and utility in urban environments worldwide.
Speaking of urban landscapes, let’s not forget the ubiquitous traffic lights guiding us on the roads. The earliest system was actually implemented for horse-drawn carriages back in 1868 in London and it used gas-lit signals. The transition to electric traffic signals occurred in the early 20th century, thanks to Garrett Morgan, who greatly improved upon the initial designs, paving the way for the three-position traffic lights we rely on today.
Now, shifting focus to our homes, let's discuss the lesser-known history of the microwave oven. Percy Spencer, an engineer exploring radar technology during World War II, serendipitously discovered its cooking potential. While working with a magnetron, he noticed a chocolate bar in his pocket had melted. Intrigued, he experimented with other foods, leading to the creation of the microwave oven, which significantly altered culinary habits worldwide.
Switching gears, consider the phenomenon of chewing gum. This confectionary delight dates back to ancient civilizations, where the Greeks chewed mastic tree resin, and the Mayans favored chicle from the sapodilla tree. However, modern chewing gum gained popularity thanks to Thomas Adams in the 19th century. Initially attempting to create a rubber substitute with chicle, Adams produced the first commercial chewing gum by accident, triggering a global craze that continues to this day.
Finally, it's worth noting the fascinating origin of the zipper. Invented by Whitcomb L. Judson in 1893 as a “clasp locker,” the initial design was not successful. It wasn’t until Gideon Sundback improved the invention, creating the
