A couple of teen geniuses from Hong Kong have invented a product that could revolutionize the world of hygiene and infection control. They’ve created a door handle that instantly destroys germs every time it is touched by human hands.

The two kids – 17-year-old Sun Ming (‘Simon’) Wong and 18-year-old King Pong (‘Michael’) Li – are students at Tam Lee Lai Fun Memorial Secondary School, in Tuen Mun, China. They realised that everyday objects such as doorknobs, handrails, shopping cart handles, and counter-tops are breeding grounds for millions of germs, so they set out to explore the possibility of creating self-disinfecting surfaces that remain germ-free all the time.

After considerable research, Simon and Michael found out that titanium dioxide is an amazing bacteria-killer. So they ground the mineral into a very fine powder to use as a coating for the handle. They also discovered that titanium dioxide is more effective when exposed to ultraviolet (UV) rays. This posed a challenge: sunlight is a natural source of UV rays, but door handles are generally used indoors. So they had to come up with an energy-efficient artificial source of UV rays.

Up until a few weeks ago, the proverbial thinking cap only had a figurative meaning, but apparently science has finally managed to catch up. A couple of American scientists have created a real thinking cap that could help people learn and make decisions quicker.

This unique device is the brainchild of psychology professor Geoff Woodman and Ph.D. student Robert Reinhart of Vanderbilt University in Tennessee and works by sending very low electrical shocks to the brain when worn. The duo claim that the electrical stimulation of certain parts of the brain could make the wearer learn new skills and make better decisions.

Indeed, studies performed on the human brain have revealed that negative voltage spikes occur in the medial-frontal cortex of the brain, milliseconds before we make a mistake. Woodman and Reinhart figured that a part of the brain can influence learning and decision making, helping us avoid the same mistakes later.

A couple of Belgian designers have come up with a new range of edible food containers that are eco-friendly, taste good, and most importantly, save people from the misery of doing dishes.

The young entrepreneurs – Helene Hoyois and Thibaut Gilquin – got the idea after hosting a party one night, after which they found themselves facing a mountain of dirty dishes to that needed cleaning. Instinctively, Thibaut turned to Helene and asked: “And if we eat the dishes?”

He was only joking at first, but the duo soon started to take the idea seriously. After a few trials, they finally managed to come up with a viable concept – containers made from a combination of potato starch, water and oil. The material is tough enough to retain all sorts of foods and sauces, but is also easily digestible.

‘Bionic Boots’ are high-tech footwear that can help you reach running speeds comparable to professional athletes like Usain Bolt. The ultra light boots feature innovative springs inspired by the Achilles tendon of ostriches or kangaroos, lending the wearer more force while running and literally putting a spring in their stride.

The boots are the brainchild of inventor Keahi Seymour, who has always been fascinated by the effortless speed and agility of ostriches, the fastest running birds on the planet, with a top speed of 45 mph. He has been working on the gadget for several years, producing dozens of prototypes in the process.

A team of engineers in China is currently involved in developing something called the ‘Air Umbrella’ – a revolutionary new device that uses blasts of air to shield people from the rain. The high-tech umbrella, shaped like a plastic microphone, is capable of producing horizontal gusts of air that repel raindrops, creating a dry, one meter wide circle around the user’s head.

There is a small catch, of course – the device works only for a short while. In true Cinderella style, the ‘magic’ wears off at the stroke of the 30th minute – the umbrella stops producing air and you’ll be drenched in no time at all. So you’d probably want to use it only if you’re confident you can get out of the rain in 30 minutes or less.

Nothing compares to the warm hug of a real person, but when there’s no one else around, this nifty little Japanese invention can do the job quite well. It’s called the ‘tranquility chair’ – its back is shaped like a giant human doll with a friendly face and long arms that can wrap around you in an affectionate embrace.

The chair is the brainchild of Japanese company UniCare – they’re selling the product for 46,000 yen ($ 419) at the International Home Care and Rehabilitation Exhibition in Tokyo. “It makes you feel safe,” said a UniCare spokesperson. “Anyone can use it, but it is designed for older people.”

Given that a quarter of Japan’s population is currently over the age of 65, and the number is expected to rise to 40 percent in coming decades, the tranquility chair is really quite apt for the Japanese market. The company has come up with a host of similar products, like ‘Life Rhythm Dolls’ that are programmed to remind owners to take their medicine or go to the toilet.

Devastated by his pet rat’s death, 13-year-old Pepeijn Bruins decided to do something really special for his furry friend. So he turned to Dutch inventors Arjen Beltman and Bart Jansen for help. Soon, Ratjetoe the rat was stuffed and converted into the world’s first radio-controlled ‘ratcopter’.

Bart and Arjen have a special talent for making dead animals fly; previously, we’d written about how they converted a dead ostrich and a cat into weird helicopters. Their last project was a flying jet powered shark. And they’ve done it again, this time helping a young boy overcome his grief over losing his best friend.

“I loved him very much,” said Pepeijn, who had to have the cancer-stricken rat put down. “He always liked to be cuddled and he would run up my clothes and hide. When I learned he had cancer and the vet had to put him to sleep I was very upset. I had seen Bart and Arjen and their flying cat, and I asked my dad if it would be possible to have the rat fly.”

16-year-old Ann Makosinski, from Victoria, Canada, has come up with a marvelous invention – a flashlight powered solely by body-heat. Her project won second prize at a local science fair, and made it all the way to the 2013 Google Science Fair, where she was declared the winner for her age group. She also updated it to a handsfree version this year – a body-heat powered headlamp, for which she won the 2014 Weston Youth Innovation Award.

Ann’s project is truly remarkable for its sheer simplicity and brilliance. I mean, it isn’t every day that you come across a light source that doesn’t use batteries, solar power, or wind energy. The device just powers on as soon as you hold it in your palm. If that isn’t genius, I don’t know what is!

The secret behind Ann’s invention is thermoelectric technology, and devices called Peltier tiles. And it’s really surprising that no one’s ever thought to use that kind of technology to power a flashlight before. Think of all the AA batteries we could avoid using!

When we wrote about the creepy Facewaver Exercise Mask last year, we thought we’d seen the worst of bizarre Japanese inventions. But now they’ve come up with an even weirder gadget – a silly-looking new product called the ‘Facial Fitness PAO’.

The PAO was designed by Japanese beauty company SHLAB – it consists of a round plastic mouthpiece with plastic paddle wings on either side. In order to use it, you simply hold the device firmly in your mouth and bob your head up and down to swing the paddles.

The company claims that performing this exercise for 30 seconds, twice a day, can significantly tone up facial muscles, making a person look much younger. They demonstrate its correct use in their two-minute advertisement, which is so absurd, I dare you to watch it with a straight face.

Threadsmiths, a Melbourne-based clothing and technology company, has created a special t-shirt that could very well revolutionize the garment industry. Their new line of 100 percent cotton t-shirts , called ‘The Cavalier’, are made of a material that repels both water and dirt. The highly resilient garments have been put through a range of tests, and miraculously, they’ve passed every single one.

Pour a cup of water on these babies and they’ll remain dry as a bone. Splash Cola or Gatorade directly on to them and all that colored liquid simply beads up and rolls off the fabric. Hose them down with a high pressure stream and they still won’t hold a drop of water. It sounds like magic, but it’s all pure science.

The technology used to create these shirts is an extreme form of water-proofing that involves modifying the fundamental nature of surfaces, making them super-hydrophobic. The company website states: “Our shirts emulate the natural hydrophobic properties of the lotus leaf.” Instead of getting absorbed by the fabric, liquids just form into droplets that slide off of it.

Let’s face it – gas masks might be incredibly useful in case of a catastrophe, but they’re not the most fashionable accessories and often make it difficult for users to interact with other people. But Israeli industrial designer, Zlil Lazarovich, is trying to change the way people perceive gas masks. She has created the world’s first ‘Social Gas Mask’ which not only looks sleek and stylish, but also allows for seamless social interactions.

With the new Social Gas Mask, you can enjoy movie nights on your couch, go outside without having people stare at you, and pretty much do everything you normally do. “The large window allows to show a greater range of facial expressions by exposing the upper cheeks, eyebrows and full width of the eyes area,” Lazarovich says. “The wide, cheeky shape of the filters gives the impression of a wide, healthy and happy face instead of a long, skeleton-like one. As opposed to current masks that often hide the user’s face, restrict communication and facial expressions, and look like an alien, the Social Gas Mask has a number of features designed to offer an empowering image and a positive experience.”

Notebook manufacturer Magnus Ferreus recently launched a quirky new product – the Onion Note. True to its name, the notebook will make you cry every time you scribble something in it. Thankfully, it doesn’t stink like an onion, it only has the same effect as cutting one.

The pages of the Onion Note have been treated with allyl propyl compounds – the same ones found in onion oil, which are responsible for bringing people to tears. You don’t have to chop up the pages for the oil to work, though. The heat caused by the friction of writing on the page will evaporate the compounds, releasing tear-inducing gas into your face.

According to Thomas, the CEO of Magnus Ferreus, we all spend a lot of time writing in notebooks, but we’ve never been emotionally moved by them. So he wanted to change that by introducing a revolutionary product we could use to ‘make notes in a dramatic way’. And what better way to do that than with an onion?

A small town in Spain has come up with a new way of dealing with dog waste – a canine public toilet. Located along a busy thoroughfare in El Vendrell, northeastern Spain, the stainless steel contraption consists of two sections placed side by side – a doggy potty and a doggy urinal.

The potty is a raised steel platform with a covered hole. Dog owners need to lift the lid for their pets to defecate, and later press a handle to flush. Jets of water are released, which carry the excrement through underground pipes into the sewer system. Right next to the potty is the urinal – also a raised platform with small holes over which dogs can squat. The public toilet is the brainchild of dog-lover Enric Girona, who has spent over ten years observing and photographing dogs. Through his work, he recognized the need for a toilet for dogs, so he set about creating one himself. “Over the years, I’ve seen that if you train and raise dogs well, these animals can be just like humans,” he explained.

Girona invented several variants of the toilet, modifying each one as he learned more and more about dog behavior. The present version of the urinal, for example, doesn’t clean itself perfectly when flushing, because need to pick the odor so they are lured to the toilet. He also had the location in mind while designing these toilets, so they’d naturally blend into surroundings like parks and other public places. “You can’t have something that clashes with the setting,” he pointed out. “The design was done with the concept of being attractive.”

What do you get when you combine Table Tennis and Football, and throw in a dash of technology? The answer is Teqball, an addictive new sport that’s becoming more popular every day. The sport involves the bouncing of a ball between opponents, off a highly sophisticated table designed to keep things fair.

To play a game of Teqball, all you need are a Teqboard and a ball. According to the official website, the Teqboard is a sporting equipment, very similar to a ping-pong table, that’s been designed keeping in mind the rules of mathematics and physics. So a ball will bounce off any point on the board, making it easy to reach and control. Although you can’t touch the board, it can withstand a great amount of pressure, making it durable and safe to use.

The ‘net’ at the center of the board is made of polycarbonate/plexiglass, ensuring that the ball bounces off it in a fair manner. Thanks to the unique design of the Teqboard, the only thing that matters in the game is talent; there’s no room for luck. The ball used for playing is a regular football, preferably a FIFA size 4.

If you thought suitcases with wheels were handy, wait till you check out this new invention. It’s an electric suitcase that not only has wheels, but is also equipped with a small motor – so instead of carrying or dragging it, and you actually get to ride it wherever you need to go. Getting by in an airport will seem a breeze with this bad boy. You just sit on it, start it up, and go!

The 15-pound, battery-operated, drivable suitcase is the brainchild of Chinese amateur inventor He Liangcai. On a full charge, the suitcase can transport two adults at 12 mph for a distance of up to 37 miles. It also has GPS navigation and a burglar alarm.
