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.

If you’ve always struggled to express your emotions, then you should seriously consider getting the Mood Sweater to do it for you. Sensoree, a San Francisco-based company, has created a new line of high-tech sweaters that display the wearer’s moods.

Along with the sweater, you need to wear a sensor on your hand. Information about your emotions are transmitted to the collar, embedded with LED lights that glow in a variety of colors. The wide turtleneck is white when unused, but glows in various colors, according to the wearer’s mood, when worn.

The emotive display is color coded: green for tranquil, Zen; blue for calm, relaxed; purple for ruffled, aroused or excited; red for nervous, in love; yellow for nirvana, ecstatic, blissful. The technology in the sweater is similar to that used in some lie detectors – it gathers information from the wearer’s sweat glands.

20-year-old Raul Oaida, a self-taught technology genius, has built the world’s first life-size LEGO car using 500,000 pieces. It’s not just a model, you can actually drive it. And the fuel costs nothing, because the car runs on air!

Oaida’s partner in this project was Australian entrepreneur, Steve Sammartino. The car was built in Romania, Oaida’s home country, and delivered to Melbourne, Australia for a test drive. Together, they named it the ‘Super Awesome Micro Project’ (I think the name is perfect!).

The engine of the car is also entirely made of LEGO. It has “four orbital engines and a total of 256 pistons.” According to the project website, the top speed isn’t very impressive, around 20 to 30 km. “We were scared of a Lego explosion so we drove it slowly,” the founders wrote. Steve and Oaida say that the project was possible only because of the internet. The two even met online, when Steve accepted Oaida’s Skype request. “I’m teaching him about business and he’s teaching me a bit about physics,” Steve told the press.

The Silic shirt is an amazing garment that just doesn’t catch a stain. No matter what you spill on it – water, soda, or even ketchup – it just rolls right off the T-shirt. Invented by San Francisco based student, Aamir Patel, the shirts are made from a material with billions of silica particles bonded to the fibers on a microscopic level.

Despite the unique material used, Silic shirts are said to feel no different from regular clothing. Patel has created a Kickstarter page for his unique invention and has already exceeded his target of raising $20,000. The campaign closes on 26^th January. The shirts are expected to go on sale online in May, at $50 apiece.

Patel has been working on the shirt project for a year-and-a-half now. For his first prototype, he simply sprayed a stain-resistant chemical on a shirt, but he realized it would last for only one wash. Then he started to think of a way to incorporate the technology right into the fabric. After several trials and errors, he finally managed to create a fabric that is stain-proof on a molecular level. Not only does the technology last longer,but  it doesn’t even irritate the skin, either. Patel says that most liquid molecules will not be able to touch the fabric because of a microscopic layer of air that forms between the liquid and fabric.

Sprayable Energy is a patent-pending invention that allows people to get all the energy benefits of caffeine without the dreaded coffee aftertaste. The spray is absorbed through the skin and distributed through the body over a period of several hours, giving the user a long-lasting caffeine buzz.

21-year-old Ben Yu and his partner Deven Soni have recently launched a campaign on crowdfunding platform Indiegogo for an innovative product called Sprayable Energy. The small plastic can contains an unscented, colorless formula that gives users that much needed boost of energy without the jitters and sudden caffeine crash. “Coffee didn’t work for me,” Yu told Inc.com. “When I ingest it, it’s like roller coaster ride of energy.” He decided to work on an alternative to the popular beverage in October 2012, while trying to get a degree in biochemistry. He started researching how nicotine patches worked, and like any young inventor, used himself as a test-subject for his experiments. His father, who holds a PhD in chemistry, also helped out, and after a lot of hard work, Ben came up with a special formula containing water, a derivative of the amino acid tyrosine, and caffeine that could be sprayed on the skin and offer the same energy buzz of coffee without the nasty taste and side-effects. Now all they needed was an extra $15,000 to develop the product line.

“It is as MAD as it looks,” British garage inventor Colin Furze says about his crazy jet-powered bicycle, Norah. Strapping a home-made jet engine to an old bike, the nutty Brit has created what may very well be the most dangerous bicycle ever.

Looking at all the outrageous things he has created over the years, one might be tempted to think he’s an engineer with a passion for insane inventions. But he’s only a plumber who likes to create wacky-yet-fascinating things in his home workshop. He is known for building the world’s longest motorbike, the fastest mobility scooter, and a gas-powered stroller, using only “tools that proper engineers would laugh at”. But he is proof that “you don’t need an expensive lathe and huge welder to create something amazing.” His latest achievement is Norah, a jet-powered bicycle able to reach speeds of up to 50 miles per hour. As you can probably imagine it’s terribly unsafe, yet incredibly fun to ride. Norah is literally one hot vehicle, as the DIY engine’s exhausts get so hot they actually turn bright red at full throttle. Instead of using a heat shield and ruining the bike’s look, he oped to make it longer and put some distance between the rider’s bum and the engine. But extreme heat isn’t the only thing you should be worried about when riding Norah.

Two Indonesian high school student have impressed judges at the national Science Project Olympiad with their ingenious air freshener made from from cow dung. Believe it or not, the organic product actually has a pleasant plant-like fragrance.

Dwi Nailul Izzah and Rintya Aprianti Miki managed to surpass 1,000 other participants at the Indonesian Science Project Olympiad (ISPO), held at the end of February, in Jakarta, and won gold medals for their original invention – an environmentally-friendly air-freshener made from cow manure. I know, that’s probably one of the last ingredients you’d expect to find in such a product, but according to the judges and everyone else who had the chance to sniff the girls’ air freshener, it has a surprisingly nice herbal fragrance. But it wasn’t just the smell that won Dwi and Rintya points. Their natural air freshener contains none of the chemicals found in similar commercially-available products, and it’s also more affordable. While a conventional 275-gram air freshener costs 39,000 Indonesian rupiah ($4), a 225-gram can of cow dung air freshener costs just $21,000 rupiah ($2). The two young inventors are getting ready to showcase their unique invention at the International Environment Project Olympiad (INEPO), in Istanbul, and are getting ready to file for a patent.
