The world's largest hand-held flashlight.

Conversion of potential energy into kinetic one.

When already in the 19th century it was possible to transmit energy without wires, but only now realized.

The video features a Tesla coil from the 19th century. It allows wireless transmission of electricity.

The fluorescent dyes in the mineral oil are slowly mixed with room temperature water.

The center of gravity is a geometric point of an absolutely solid body, through which the resultant force of all gravity forces passes.

Under the force of gravity, the raisin descends to the bottom. Then gas bubbles form on the rough surface of the raisin.

When there are enough bubbles, the expulsive force (Archimedes' principle) will cause the raisin to rise to the surface of the carbonated water. At the surface, the gas bubbles burst, and gravity causes the raisin to sink back down again.

Angular cubic prism

A beam of light entering a mirrored reflective prism always exits along a parallel path.

Physicists set out to play soundtracks from popular movies on a Tesla reel.

RGB Triad

That's how the three primary colors can be used to create a multicolor image.

Visual experiment demonstrating that any two objects in a vacuum will fall at the same speed.

Flash paper (nitrocellulose)

It has a characteristic combustion: no hint of smoldering, the jet of flame hits not only upwards, but also in all directions, indicating that in the "hearth of combustion" material burns without the participation of air oxygen. Finally, the fact that not only smoke, but also ash is not produced.

Gas flint lighter with ignition from a flintlock. The construction consists of a hardened steel flint wheel and a piece of mish-metal sharps.

Newton Disc

Allows to obtain white color from several rays of various colors.
The disk is divided into sectors of colors of the visible spectrum. When rotating it at high speed, you can observe how these colors merge to form a white tone.

Homemade mini-acoustic levitator.

Using an acrylic prism and a gas pedal, we "catch" the electrons.

They easily penetrate deep into the acrylic and are quickly slowed down by colliding with the plastic molecules.

High voltage and hydrogen.

The action of Ampere force.

Ferromagnetic liquid + magnet + high voltage.

Metal ball on platform with PID controller.
