Cutting glass under water.

Scissors make a micro-crack, capillary effect completes the process, breaking off pieces of glass. The splitting occurs due to the wedging effect of the capillary water.

Demonstration of the diesel engine operation

The rapid compression of air in a closed volume increases its temperature so much that some substances can ignite

A flame conducts an electric current.

Jacob's ladder

The apparatus consists of a high voltage power supply and two electrodes arranged in a vertical plane at an angle to each other.

During operation it is possible to observe the formation and movement of an electric arc from the bottom to the top of the electrodes. That effect is explained by the fact that the arc consists of plasma heated to 5000-7000°C, it warms the air around itself and rises up, pulling the arc cord behind it.

The Lorentz force is commonly referred to as the force affecting an electron that moves and is in a magnetic field.

It is a combination of two forces – magnetic, electric, concentrated on the charge.

Radiometer is an instrument designed to measure the energy characteristics of radiation using its thermal effect.

Electromechanical pendulum with magnetic feedback.

Thermogravitational convection

Convection is a type of heat exchange (heat transfer) in which internal energy is transferred by jets and flows of the substance itself.

The simplest jet engine. Alcohol + air + booster converter.

Acoustic levitation

It is based on the creation of a standing sound wave in the air capable of keeping particles suspended.
