In 2010, Colgate Palmolive sued its competitor GlaxoSmithKline over the use of the nurdle image on toothpaste packaging, leading to a legal dispute that was settled out of court. The term “nurdle” highlights the quirky side of everyday objects and the importance of branding in the commercial world.
Houseplants Are Good for You
Having houseplants in your home is not only aesthetically pleasing but also beneficial for your health. Studies have shown that indoor plants can reduce airborne molds and bacteria by up to 60 percent, improving air quality. Plants like English Ivy, peace lilies, and Boston ferns are particularly effective at cleaning the air and regulating humidity. Additionally, houseplants have been found to promote mental well-being by reducing stress and enhancing mood. They can also make people more contemplative and self-reflective, connecting them to nature and loved ones who may have given the plants as gifts.
Salt Was Used as Currency
Salt, a staple in every kitchen today, was once so valuable that it was used as currency. The ancient Romans paid their soldiers in rations of salt, a practice that gave rise to the word “salary,” derived from the Latin word “salarium.” Salt’s value stemmed from its ability to preserve food, making it an essential commodity for long journeys and everyday life. This historical use of salt as money underscores its critical role in human civilization and its profound impact on trade and economy.
A Gallon of Gasoline Contains 31,000 Calories
While it’s certainly not recommended to consume gasoline, a gallon of it contains approximately 31,000 calories. This immense energy content highlights the efficiency of gasoline as a fuel source. Scientists discovered this fact while comparing the energy output of gasoline to that of a human-powered bicycle. They found that a person could theoretically bike about 912 miles on the energy equivalent of a single gallon of gasoline. This comparison emphasizes the incredible energy density of gasoline and its importance in powering modern transportation.
Your Smartphone Could Send Astronauts to the Moon
The smartphone you carry in your pocket is millions of times more powerful than the computers used by NASA during the Apollo missions to the moon.

In contrast, the processing power of a modern smartphone can handle calculations and tasks that would have been unimaginable in the 1960s. This astonishing fact underscores the rapid advancements in technology and the remarkable capabilities of modern devices.
Rice is the Oldest Food that We Still Eat Today
Rice, a dietary staple for billions of people worldwide, has been cultivated for between 12,000 and 15,000 years. All modern domesticated rice varieties can be traced back to a single crop in the Pearl River Valley of ancient China. This ancient grain has sustained civilizations and remains a fundamental part of diets across Asia, Africa, and the Americas. Its ability to grow in diverse climates and its nutritional value have made rice a cornerstone of agricultural development and human survival. The enduring presence of rice in our diets highlights its nutritional value and the agricultural ingenuity of early human societies.
Dogs Aren’t Actually Colorblind
Contrary to popular belief, dogs are not colorblind. They can see colors, but their vision is limited compared to humans. Dogs perceive yellows, blues, and violets clearly but have difficulty distinguishing reds, oranges, and greens. This limited color vision is offset by their superior night vision and ability to detect motion. Understanding the true nature of canine vision can help dog owners create more stimulating and enriching environments for their pets. This insight into canine vision challenges the widespread misconception and reveals the unique adaptations that allow dogs to thrive in various lighting conditions.
Pen Caps Have Holes to Prevent Choking
The small hole at the top of a pen cap is a lifesaving design feature. It ensures that if a child or an adult accidentally swallows the cap, airflow is maintained, reducing the risk of choking. This thoughtful design is especially common in mass-produced pens like the Bic Cristal. The simple yet effective addition of a hole in the cap exemplifies how everyday items are engineered with safety in mind. This seemingly minor detail highlights the importance of considering safety in product design, especially for items that are commonly used by children.
Berries Aren’t What You Think They Are
Botanically speaking, many fruits commonly thought of as berries, like strawberries and raspberries, are not true berries. True berries, according to botanical definitions, must have three layers: a protective outer layer, a fleshy middle, and an inner part that holds the seeds. Blueberries and cranberries fit this definition, while bananas, kiwis, and even tomatoes are technically berries. This surprising classification reveals the complexity of botanical terminology and challenges our everyday assumptions about fruit. Understanding the true botanical definitions of fruits can enhance our appreciation of their diversity and the intricacies of plant biology.
It Takes a Lot of Bees to Make Honey
Producing honey is a monumental task for a colony of bees. An individual bee will produce only about one-twelfth of a teaspoon of honey in its lifetime. A single colony, consisting of 20,000 to 60,000 bees, can produce a significant amount of honey collectively. Honey is not only a high-energy food but also has natural preservatives, allowing it to last indefinitely if stored properly. This fact highlights the industrious nature of bees and the incredible effort involved in creating honey. The process of honey production exemplifies the remarkable cooperation and efficiency within a bee colony, showcasing the natural world’s intricate systems.
Albert Einstein Co-Invented the Refrigerator
