There is such a statement that any new technology is no different from magic. At first, children are delighted with a fountain pen, but with age it no longer seems to be something unusual. Adults are rarely surprised at something, but still there are inventions that delight children. Let's talk about them.
3D sensible holograms
Until 2015, the only advancement in holograms was the digital resurrection of the Coachella concert by Tupac Shakur. Unfortunately, this could not be called a full-fledged hologram, it was just a special CGI reflection that was incorrectly named. The Japanese scientists saw how disappointed the world was, so they immediately began to work on a real hologram.
Scientists at the Tokyo and Nagoya institutes began to work together to finally create a tangible hologram. If you do not go into complex physics, then everything is simple: the image experts took a very fast light beam, which is called a femtosecond laser. It was fed with supernatural light. From this appeared hundreds of bright dots, which are called voxels. The latter can be used in all types of three-dimensional holograms. Thus, real holograms appeared, which cannot be compared with the invention of Tupac Shakur.
Interestingly, after being touched, the voxels emit an impulse that is perfectly felt by humans. A top Japanese researcher has compared this impulse to sandpaper. Unfortunately, it will not be possible to produce such holograms on an industrial scale yet, which is a pity. Imagine how much the gaming industry, television, movies, not to mention the sex industry would change.

Bulletproof Gel
Even a child knows that a bullet kills a person, an animal, and penetrates many materials. For this reason, military organizations and law enforcement agencies are concerned about the safety of employees. Since weapons are constantly being improved, the past methods of protection often do not work, and therefore new ones have to be invented. Now the organs have even got a ceramic vest on their balance sheet, which is capable of breaking bullets on impact. But the problem is that its rigidity limits its scope. The combination of carbon and Kevlar can protect the human body, but it breaks down when combined with ordinary glue.
A shatterproof flexible material is best to prevent the employee from turning into Swiss cheese. This product is D3O gel. Although it sounds like something from the "Star Wars", but nevertheless, the UK Department of Defense in 2009 found the invention extremely useful. Interestingly, in a calm state, the substance remains pliable, but hardens during impact.
Transparent forest
It has long been known that metal is much stronger than wood. Students at the University of Maryland created translucent wood that was many times stronger than steel.
The trees became translucent as a result of the students stripping the wood from the lignin, which gave the wood its yellowish color. After that, epoxy resin was introduced into the wood fibers, which gave strength. Now the wood has become unlike the material from which paper or matches are made, it turned out to be chromatically naked. Thus, it is equivalent in strength to metal, and in transparency to glass. It's all about epoxy.
Burn spray
Burning in the fire oh how sad. When a person burns alive, he experiences the worst pain that can be. Pennsylvania soldier Matt Uram knows this firsthand. He was lucky because a newfangled therapy for burns appeared - a spray.
The technology is that stem cells are extracted from a piece of healthy skin and weighed in liquid. The latter is applied to damaged tissue. By the way, the drug can even be in the form of cologne. Doctors conducted an experiment with third-degree burns on Uram's arm. As a result, a few days after the experiment, he had healthy and clear skin. It turns out that only a small piece of leather with a postage stamp was needed for the rescue.
3D printer
People have long been trying to apply three-dimensional printing to completely different objects: dentures, chocolate bars or eggs, and so on. But there were also large-scale things. So, in 2017, scientists at the University of Massachusetts talked about using a rotating robotic arm in order to print a large foam dome. Interestingly, it took less than fourteen hours. By the way, the volume printer can adapt to different thicknesses of building materials and is also suitable for absolutely any building.
Breathalyzer for detecting diseases
We are all accustomed to the fact that drunk drivers are checked with the help of a breathalyzer, but now everything will change. Back in 2016, studies were carried out that allowed a breathalyzer to check for diseases such as kidney disease or ovarian cancer.
The device contains particles of gold and carbon, which are separated into separate layers. The layers begin to interact in order to detect volatile organic compounds that are contained in human respiration.
Surgeon robots
It is possible that the time is not far off when robots will oust people from many jobs. Now artificial intelligence can only cope with simple actions, but, for example, they cannot perform an operation, since this requires human qualities. In 2016, an apparatus was invented that is able to identify a damaged area of an organ and remove it. The device is still being tested on pigs, but, perhaps, the turn of people will soon come.
Breath Monitor T-Shirts
In 2017, an inventor proposed creating T-shirts that show lung health in real time. Such a respiration monitor can be worn quite often, the only problem will be where to buy this miracle of technology.
Bacteria paint pictures
Believe it or not, scientists have been able to program bacteria to leave images behind when exposed to light. Thus, scientists were able to create images of fruits, lizards and even SuperMario, which flew over the drainpipe.
