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

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

Angular cubic prism

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

RGB Triad

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

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.

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

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.

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.

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.

Ferromagnetic liquid + magnet + high voltage.

Metal ball on platform with PID controller.

The action of Ampere force.

Interference in thin films is a phenomenon resulting from the separation of a light beam by reflection from the upper and lower boundaries of a thin film.

The Coanda effect in action.

Centrifugal force visually.
