Can an empty wine bottle refill by itself? Is it possible to break the bottom of a bottle without making it turn into smithereens? This may sound as ‘magic’, but in reality it is nothing more than… application of the laws of physics. Here you can see some “tricks” with which you can impress your friends, but in reality they simply “obey” the laws of Nature, writes Douglas Main in Popular Science, such as presented by Tim Shaw in the show «None of the Above» on the National Geographic Channel.
1. The trick with an empty wine bottle
Empty the contents of a bottle of wine in a bowl and allow minimal amount in the bottle. Then place the bottle in the microwave for about three minutes.

Normally I don’t post the articles like this, but these pictures really astonished me so I decided to share them with the readers of my blog who love optical illusions and are fond of the paranormal.
A private collector from Spain has a unique collection of old paintings with stereo effect, which makes the image change at an angle.

Everyone has limits, for example, how fast he can run or how long he can stay without water. But what about the limitations of our five senses, which in essence are the tools we use to perceive our environment?
Approximately one quarter of the brain is involved in visual functions, so the sight is unquestionably the most important sense for our perception of the world.
1. The visible spectrum
It is certainly the most well-known limit of our senses. The human eye recognizes light with a wavelength between 390 and 750 nanometers. At the same time, some animals are able to perceive light at other wavelengths.

In the following article you will find some of the best optical illusions and visual paradoxes.
1. Magic stairs
Focus on the stairs and you will see that in a while it will turn upside down.
The first thing that impresses is definitely its name!

Psychologists from the University of Edinburgh and the Medical Research Council (MRC) in Britain concluded that those who “die” and come back to life describe experiences that are merely “dysfunctional manifestations of physiological brain functions“. Continue reading
