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.

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.

In the current experiment, the initial beam hits perpendicularly to the air-glass boundary, thus refraction at the entrance is absent.

Physicists know no pity for mosquitoes!

Visualization of how a lens refracts the sun's rays.

Relationship of gravitational potential energy and angular velocity conservation.

Way to gently pour liquids from one container to another without spilling a drop.

Fascinating experiment you can easily repeat at home.

Copper is not magnetic

A falling magnet generates a current in the pipe.

Our daily life through the prism of a thermal camera.
