Many naively believe that with the graduation of a school or university, the learning process ends. It seems that further knowledge simply does not make sense: after all, who in ordinary life will need all these cosines, sines, and chemical formulas? However, there are those who do not lose interest in the world even after graduating from the eleventh grade.

Even looking at ordinary objects, such people are curious: because each of the most ordinary things can store an infinite number of puzzles and secrets. Today we have compiled a collection of such cognitive facts, thanks to which one can still and still be surprised at how interesting our world is.

Chemical reaction "Toothpaste for an elephant"

This experiment, which chemists are very fond of surprising children and adult amateurs, occurs with the allocation very large amount of foam. In its process, which is catalyzed by iodide ions, hydrogen peroxide decomposes. As a result, a large amount of hot foam appears. Sometimes it is painted in different colors, or it can even be striped - just like toothpaste. But because of the huge amount of substance, an impressive experience was called the manufacture of "elephant toothpaste."

Wolf territory

Scientists tracked with GPS how wolves mark their territory, trying not to hurt each other's possessions.

In a limited territory, only a certain number of wolves have the opportunity to feed themselves, and a flock does not let outsiders enter its territory. As the map shows, they themselves do not go there.

From textbook to reality

With an electron microscope, organic particles can be seen. It turns out that the pictures from the textbooks did not deceive us - in reality they look like that.

All of these images from chemistry textbooks have a reason

Interactive sand topographic map

This thing can be called the sandbox of the future. Its main elements are a projector, a sand-filled container and a game console. Also above the box is a detector that allows you to quickly measure changes in the level of sand. The received data is sent to a computer, and then processed using a special program. That, in turn, transfers information to the projector, where the color is determined by all the canons of topography.
