Propane "rocket"🚀

The following main elements are attached to the wooden base of the gun: propane burner, flexible pvc tube bent in a spiral and rigid pvc tube - "muzzle".

Geeks watch out! You might be stuck 😄

Demonstration of the capacitor installation process on the board automatically.

Descent jet

An air current made up of perturbed air masses descending from the wing, stabilizer, other supporting and controlling surfaces, and the fuselage of the aircraft.

The Prandtl-Glauert effect

It occurs as a high-speed flying object creates a region of high air pressure in front of itself, and a region of low pressure is formed behind it.

When you're a Harry Potter fan and also an engineer, you have no trouble building such a marvel 💁🏻‍♀️

Watch with sound 🔈

A curious spectacle: how Wi-FI spreads around the apartment.

Perfect illustration of inertia

And inertia is a physical phenomenon whereby a body keeps its velocity constant or at rest when no other bodies are acting on it.

Causes of collapses and potholes.

Great magnetic field work 🧲

It's the field generated by a magnet or a conductor through which an electric current runs.

Operation of a wedge-air rocket engine.💥

A type of liquid rocket engine with a wedge-shaped nozzle that maintains aerodynamic efficiency over a wide range of altitudes above the Earth's surface with varying atmospheric pressures.

Ice roller couldn't crush a golf ball

After compression of polymers, the density of an ordinary golf ball is equal to 40 kilograms of steel compressed to four centimeters in diameter.

Tensegrity is the principle of constructing structures of rods and cables, with the rods running in compression and the cables operating in tension.

Uncanny welding💥

Fast air moving around objects reduces pressure, allowing them to float.

The shock wave created by an airplane as it gains speed generates vapor cones.

The physical effects of an airplane flying so fast through the air are shock waves. Shock waves form around the airplane as it gains speed and approaches the speed of sound.

What's intriguing is the property of the vibration causing this thing to rotate in the opposite direction.

"Drunk glasses"

Curious concept, wine lovers will appreciate it.

Electrical short circuit.

Color laser + smoke generator, stunning and mesmerizing effect.
