That's what new technologies are capable of in collaboration with the 5G network A surgeon from London remotely performed an operation on a banana that was in California at the time 🍌

The reaction of pure metallic sodium and water! Stunning effect

Double pendulum This kind of pendulum is a simple physical system that exhibits a variety of dynamic behavior with significant dependence on initial conditions.

Nemo Observatory: A typhoon simulation that can be experienced individually on a chair in the center of the storm.

Human Slingshot Amusement park ride engineers are creative, innovative and well versed in mathematics and civil engineering. They design new rides on a computer with their knowledge of physics, collaborate with other engineers to create an attraction using appropriate materials, and decide how to effectively maintain it.

If you were wondering what is the maximum weight a tooth can withstand?! Then this video is for you

This tiny car, powered by a battery, overcomes gravity due to centripetal acceleration and light friction on the glass surface. At sufficient speed, the normal force to the surface provides centripetal acceleration.

Unusual development ZipStitch, capable of stitching wounds seamlessly. According to the manufacturers, it is 8 times stronger than the stitches that are applied in the hospital

A demonstration of how density and gravity work!

The illusion of a silver egg. When smoking, the shell is covered with a thin layer of coal, and air remains in the pores. When immersed in water, the egg is "clothed" in an air shell, it is she who refracts light and creates the appearance of a mirror surface.

Plastic water bottle under pressure

Bernoulli's Principle. Fast air moving around the objects, reduces the pressure, allowing them to swim. Here it is simple with the help of a Hairdryer, so you can try at home.

Domino effect

Interesting sound of the floor In Japanese castles and temples, you can often find the so-called Nightingale floor. It is impossible to walk through it quietly — there is a sound similar to a nightingale whistle or just a bird chirping. This effect was achieved by fixing the boards to the floor in the form of an inverted letter V. The pressure on the floor causes the "Nightingale" effect. Moreover, it increases when walking on tiptoe, because the pressure at the same time is greater than from a full foot.

In 1984, Bruce McCandless went into outer space from the Challenger spacecraft and turned on a liquid nitrogen jetpack, with which he managed to fly into outer space at a distance of 97 m from the ship. Bruce had no insurance, and if the satchel broke, the astronaut would not come back in any way. This is how maximum trust in engineers looks like!

People in zero gravity are about five centimeters taller. On Earth, gravity presses on the spine, but in space, nothing presses on the spine, and it spreads out to its full length.

Fascinating property of ferromagnetic liquid In magnetic fields, it is affected by a force caused by inhomogeneity or discontinuities of the magnetic characteristics of the medium, under the influence of which the ferromagnetic liquid can move as a whole and change the shape of the surface.
