Ordinary keys, and what a good effect when they move at the same time.

⚙️ Engineering

Display of a perfect combination of magnetic levitation and electromagnetic induction.

⚙️ Engineering

Experiment with quartz beaker, microwave oven and magnesium. As a result, we can observe a clot of plasma.

⚙️ Engineering

That's the incredibly strong Isotruss material.

⚙️ Engineering

Homemade mini-acoustic levitator.

⚙️ Engineering

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.

⚙️ Engineering

Ferromagnetic effect🧲

A neodymium magnet turns nails into magnets: the cap is the north pole, the tip the south pole.

⚙️ Engineering

A homemade vortex gun in action.

⚙️ Engineering

Jet Engine

Experiment with a mannequin demonstrating what would happen to a face if it were accidentally hit by a jet engine.

⚙️ Engineering

The Coandă Effect

The effect is actually quite widely used; from airplanes to windshield washers in cars and even in air conditioner designs.

Burning cup filled with water

⚙️ Engineering

That solar panel "blooms" like a sunflower and produces 40% more electricity.

⚙️ Engineering

The Painful Magic of High Voltage Levitation

And keep in mind, you have to be extremely careful with electricity.

⚙️ Engineering

Creating a magnet 🧲

If you urgently need a magnet, but don't have one at home, you can make one from the available materials that everyone has...

⚙️ Engineering

Shape memory effect

⚙️ Engineering

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.

⚙️ Engineering

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.

⚙️ Engineering

When the volume level gets above 155-160 dB, the car starts shaking and almost bursting with vibration. At low frequencies, the windows burst.

⚙️ Engineering

A clear process on the fuel consumption in a rocket.

⚙️ Engineering

Levitating pots with houseplants

The levitation effect is realized with the help of magnets in the planter and the stand.
