"Chemical clock"😱 Three different solutions get mixed in a chemical beaker placed on a magnetic stirrer. After that, you can observe the cyclic color change of the mixture of solutions (colorless - gold - blue).

Ammonium + titanium Titanium powder is widely used in pyrotechnics💥 The video shows an example of such a reaction between ammonium perchlorate and titanium powder

How is this possible😱 Demonstration of subtractive color mixing with a cube.

Recreating a Tesla coil from 1891 It allows wireless transmission of electricity. 📌 And it is also used to produce high voltage, low current and high frequency AC current.

A blogger assembled a "Chronos ring" shooting at 330,000 frames per second😱 With this monster he filmed oxy-acetylene explosions.

Wildfire is a dangerous liquid created by the mages of the Alchemists Guild. Wildfire is extremely easy to ignite, and then it explodes with great force, starting a fire that can't be put out by anything except a lot of sand. The flame that creates a wildfire is green in color. Yet in our case it is boric acid with methanol.

A Wilson Chamber to observe the radioactive decay of uranium A Wilson Chamber is a track detector of elementary charged particles. Invented by C. Wilson in 1912. (Nobel Prize in 1927). With Wilson Chamber, tracks of charged particles become visible due to condensation of oversaturated steam on gas ions formed by a charged particle.

The human eye in macro photography 👁 The iris has this uneven structure due to the muscle fibers. It is a muscle that regulates the incoming light with its contraction and relaxation.

Desktop version of the Tensegrity magnetic table Tensegrity is the principle of constructing structures of rods and cables in which the rods work in compression and the cables work in tension.

Thermal imager + piece of sodium + water = a fantastic sight 😍

The leukocyte catches up with the dead erythrocyte Yeah, it's also the responsibility of the most famous immune cell☝🏻 After all, it's not just foreign cells that do harm to the body, but also dead cells of our own.

Car prototype by Leonardo da Vinci An exact copy of this device is kept in the Institute and Museum of the History of Science in Florence, Italy.

Magnetic Sandglass Ferromagnetic sand is collected over a neodymium magnet in a wooden base.

How does the pulse oximeter work? The principle of its operation is based on the infrared radiation of LEDs. Blood elements and oxygen absorb light waves of different wavelengths. And the device analyzes the amount of light transmitted and shows it in the form of numbers.

Curious collabration of engineering and gaming technology 😅 Wanna play in a capsule like this?

Kinetic sculpture of a stepper motor The base provides a pulse of rotational energy for the transformation.

A Japanese created a self-assembling Rubik's cube😲 The levitating Rubik's cube self-assembles all segments of the same color on the same side thanks to built-in motors and axis rotation sensors.

No montage, it's our brain's perception of color 😉 From a physical point of view, color does not exist. Color vision is only the ability to distinguish the wave spectra of light. Everything else is a fantasy of our brain and peculiarities of psychological perception.

Visualizing Gravity with Marbles Balls accelerate as they approach the center. This is skillfully illustrated by the work of black holes: they suck in matter faster and faster as they approach the event horizon.

Myosin "steps" on actin This happens in our muscles - iosin heads step on actin filaments☝🏻. It is this mechanism that ensures muscle contraction.
