In order to blow out plastic containers, you need a compressor. It is the compressor that generates the pressure by which the air jet is delivered.

The piston pump

When the piston moves upward, the liquid under atmospheric pressure enters the tube, lifts the bottom valve and moves behind the piston.

When the piston moves downward, the liquid under the piston presses on the bottom valve and it closes.
At the same time, the pressure of the fluid opens the valve inside the piston, and this fluid moves into the space above the piston.

Rehbinder Effect visual demonstration

It represents an adsorption reduction of strength — a change in the mechanical properties of solids due to physical and chemical processes causing a decrease in the surface energy of the body.

In the case of a crystalline solid, what is also significant is that the crystal exhibits the defects in structure necessary for the nucleation of cracks, which then propagate under the influence of the medium.

In fact, it is an optical illusion.

In this video, the frame rate of the camera unit coincides with the rotation frequency of the helicopter blades. That is why it appears that the blades are not rotating.

Effect of temperature on the material

The vast majority of substances expand when heated.

This can easily be explained in terms of the mechanical theory of heat, since the molecules or atoms of a substance begin to move faster when heated.

The law of conservation of energy

A classic illustration of the principle is a spring or mathematical pendulum with negligibly small damping.

In the case of a spring pendulum, the potential energy of the deformed spring is converted into kinetic energy of the weight and back as it oscillates.

Likewise in the case of a mathematical pendulum, the potential energy of a weight in a field of gravity behaves in a similar way.
