Throughout the ages, human creativity has led to remarkable inventions that have transformed lives, influenced societies, and advanced civilizations. From the invention of the wheel to the rise of the internet, these milestones have reshaped the course of history. However, not every creation has lived up to its potential.
Among the sea of innovation, some inventions, despite their creators' good intentions, have vanished into obscurity due to their impracticality, inefficiency, or outright absurdity. This list takes a playful look at the 10 most pointless inventions in human history. It showcases those strange concepts that leave us pondering, 'What were they thinking?'
From gadgets that address non-existent problems to devices that make life more complicated instead of easier, these inventions serve as a humorous reminder that failure can often be the first step towards eventual success. So, let’s explore the fun side of innovation and take a look at the creations that history, wisely, chose to forget.
10. The Pet Rock

In the mid-1970s, the Pet Rock became a cultural sensation, arguably one of the most pointless yet surprisingly successful inventions in consumer history. Its inventor, Gary Dahl, marketed these regular stones as if they were live pets, complete with a carrying case and an all-encompassing manual for their care and training. Despite offering no interaction, growth, or any real function other than sitting still, the Pet Rock captured the public’s imagination, becoming a fleeting but intense trend.
This invention perfectly exemplifies how savvy marketing can create a demand for a product that, at its essence, serves no real purpose and is utterly useless. The Pet Rock craze is a humorous reflection of consumer culture’s eccentricities and the power of novelty. It reminds us that the most impractical inventions can become memorable chapters in history—not for their utility, but for their ability to resonate with the spirit of a specific era.
9. The USB Pet Rock

Years after the original Pet Rock took the 1970s by storm, a modern version of this iconic useless invention appeared: the USB Pet Rock. This iteration, a rock with a USB cable attached for plugging into your computer, offered absolutely no digital functionality. It didn’t store data, boost performance, or interact with software in any way. Essentially, it was just a rock with a cord that wasted a precious USB port.
The USB Pet Rock acts as a playful tribute to its predecessor, tapping into nostalgia and the absurdity of connecting a natural object to the cutting edge of modern technology. While it could be seen as a comment on simplicity in an increasingly complex digital age, it remains an entirely useless invention, underscoring how certain ideas are recycled for new generations—often more for amusement than practicality.
8. Diet Water

In 2004, the concept of 'Diet Water' was introduced by Sapporo, a company better known for its beer, with the launch of its 'Diet Water' in Japan. This product claimed to offer all the benefits of regular water, but with added weight loss properties, despite water naturally containing zero calories. Sapporo’s Diet Water was infused with 'peptides' that were purported to aid in weight loss, targeting consumers eager to shed pounds with minimal effort.
The creation of Sapporo Diet Water highlights the lengths to which the diet industry can go to exploit the desire for weight loss solutions. It capitalizes on the widespread yearning for quick health fixes, repackaging a basic necessity as a marketed, health-boosting product.
Despite its bold claims, Diet Water is often pointed to as a quintessential example of a completely unnecessary product, underscoring the absurdity of some health trends. This marketing episode serves as a cautionary tale about the importance of critically examining diet products, reminding us that not all innovations offer real value beyond their novelty.
7. The DVD Rewinder

In a mix of technological confusion and pure novelty, the DVD Rewinder was created as a real product that capitalized on the nostalgia of VHS tapes. Unlike VHS tapes, which need rewinding to preserve their longevity and functionality, DVDs don’t require such a process due to their digital format. Therefore, the DVD Rewinder stands as a symbol of technological excess, providing a solution to a non-existent problem in the world of digital media.
Promoted with a playful, tongue-in-cheek approach, the device was more of a humorous gift than a practical product. It catered to those either fond of the act of rewinding tapes or simply unaware of how DVDs function. Despite its obvious lack of usefulness, the DVD Rewinder highlights the quirky side of consumer electronics, where nostalgia and humor can generate a market for an invention that, by all reasonable standards, serves no practical purpose.
6. The Banana Slicer

The Banana Slicer is a kitchen gadget designed to slice an entire banana into uniform pieces with one quick motion. While it might seem like a convenient tool for making fruit salads or toppings, its necessity is debatable. Bananas, with their soft texture, are easily sliced with a regular knife, and the slicer’s one-size-fits-all design doesn’t accommodate varying banana sizes or shapes. This leads to an invention that, while marginally useful for some, is mostly redundant for most banana-related kitchen tasks.
This product exemplifies the trend of creating hyper-specific kitchen tools aimed at solving very minor inconveniences. The existence of the Banana Slicer in the marketplace reflects a broader trend of kitchen gadgets becoming oversaturated, leading to the creation of products with highly specialized uses. Despite its intention to simplify a basic task, the slicer serves as a humorous example of when the quest for convenience in kitchen tools goes a bit too far, offering a solution to a problem that hardly anyone would even consider an issue.
5. The Goldfish Walker

In a bizarre attempt to combine pet care with whimsy, the Goldfish Walker stands out as one of the more outlandish and unnecessary inventions in recent times. Designed to allow goldfish owners to take their aquatic pets on a 'walk,' this device consists of a transparent, water-filled tank mounted on wheels. The idea behind the Goldfish Walker was to provide pet fish with a change of scenery and the experience of being outside, despite the obvious fact that fish are unlikely to perceive their surroundings in this way.
The invention highlights the human tendency to project needs onto pets that don’t share the same desires or perceptions as land animals like dogs or cats. While the Goldfish Walker might have been created with the best intentions to improve the lives of pet fish, it ultimately serves no real purpose for the animals it was designed for. It’s a prime example of how far pet owners are willing to go to involve their unconventional pets in everyday activities, even when those activities offer no genuine benefit to the animals. This device amusingly underscores the human need for connection with pets, no matter how impractical or unnecessary the means may be.
4. The USB Humping Dog

The USB Humping Dog is a novelty gadget that, when plugged into a USB port, mimics a dog performing a repetitive humping motion. This invention offers no storage or practical function as a USB device. Its sole purpose is to provide amusement through its comical behavior. Appearing in the mid-2000s, the gadget became a popular gag gift, symbolizing the era’s fascination with quirky and humorous tech accessories that served no real utility other than to generate laughs.
This product represents the height of novelty in the tech world, where the boundary between technology and toys becomes indistinct. While entertaining, the USB Humping Dog also underscores an intriguing aspect of consumer culture, where delight in uselessness becomes a form of entertainment. It serves as a commentary on the surge of USB gadgets at the time, many of which were of questionable utility. Despite its lack of practical function, the USB Humping Dog remains a memorable piece of tech memorabilia, reminding us of the humorous side of technological progress.
3. The Shoe Umbrella

The Shoe Umbrella is a gadget designed to shield footwear from rain, splashes, and wet conditions. Attached to shoes with a small frame, these miniature umbrellas aim to keep the wearer’s feet dry and their shoes free from water or mud. While it may appeal to those concerned with maintaining the look of their shoes, the practicality and effectiveness of Shoe Umbrellas often come into question.
Critics argue that Shoe Umbrellas don’t provide adequate protection against rain, especially in windy weather or when the rain is coming from the side. Furthermore, their small size and the inconvenience of attaching them to shoes make them less efficient than simply wearing waterproof shoes or carrying a regular umbrella. They are also often seen as a fashion misstep, drawing unwanted attention to the wearer’s feet in an unflattering way.
The Shoe Umbrella reflects a trend of creating products to solve very specific problems, sometimes at the cost of practicality and style. While it attempts to address the issue of wet and muddy shoes, it often causes more inconvenience than simply preparing for bad weather with more conventional solutions. This invention serves as a quirky reminder that not every problem requires an innovative or high-tech fix, especially when traditional methods work just fine.
2. The Necktie Flask

The Necktie Flask is an inventive yet questionable attempt to combine fashion with hidden functionality, catering to those who wish to discreetly carry their drink of choice. Designed to look like an ordinary necktie, it features a hidden compartment with a small nozzle near the tip, allowing the wearer to sip beverages on the go. While it may seem like a clever accessory for social gatherings where drinks are expensive or unavailable, its practicality and appropriateness remain in doubt.
This invention raises concerns for promoting the covert consumption of alcohol in environments where it may be disapproved of or prohibited. The flask’s small capacity and the risk of spills and stains further diminish its practicality. Additionally, the Necktie Flask often draws attention, which can create uncomfortable situations. Although creative in its concealment approach, this product illustrates how some inventions, despite being innovative, fail to strike a balance between novelty and genuine usefulness or social norms.
1. The Walking Sleeping Bag

The Walking Sleeping Bag, designed to allow wearers to walk around while staying snug in their bedding, represents a clash between convenience and practicality. This invention adds legs to a traditional sleeping bag, theoretically merging the comfort of warmth with the mobility to move. While it may seem appealing for camping trips or chilly winter nights, its practical use is questionable, as the design complicates the purpose of a sleeping bag.
In reality, the mobility promised by the Walking Sleeping Bag is far from practical, and the product often turns out to be more of a hindrance than a help. Walking in it feels awkward, and it doesn’t serve as a suitable replacement for proper outdoor gear. Additionally, the design undermines the very purpose of a sleeping bag—to keep the user insulated and warm—by introducing gaps that can let in drafts, making it less effective at trapping heat. This invention serves as a humorous reminder that not all innovations improve our lives, and sometimes it's best to stick with simpler, tried-and-true solutions.
