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.

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

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

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

Fascinating experiment you can easily repeat at home.

Relationship of gravitational potential energy and angular velocity conservation.

Copper is not magnetic

A falling magnet generates a current in the pipe.

Physicists know no pity for mosquitoes!
