Simple silver verification for authenticity

Due to its conductive properties, genuine silver moves much slower down the magnetic slide than silver diluted with various impurities.

Induction heating

A method of non-contact heating with high frequency and high magnitude currents of electrically conductive materials.

⚙️ Engineering

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.

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.
