When the shell is covered with a thin layer of charcoal, air remains in the pores.

Immersed in water, the egg is "clothed" in an air shell, which refracts light and creates a mirror-like surface.

Interesting visualization of keyboard play.

A funny manifestation of static electricity.

The Weissenberg effect

An effect characteristic of some non-Newtonian fluids. Instead of being thrown outward, a chain of polymers is coiled onto a rod.

Technically, this phenomenon is as follows: if a rotating rod is placed in a container with a polymer solution, the liquid level around the rod will begin to rise, the solution will be "wrapped" around the rod.

A Christmas balloon that generates snow

It required a power supply, a cooling fan, radiators and a PC CPU cooler.

The creator cut a tiny snowman out of aluminum so that the snow could grow somewhere. A couple of 2 watt resistors were also added to evaporate water.

And you can have fun with physics, too.

Bursera graveolens.

The fire creates a mesmerizing "mini sunset" effect on it

In Switzerland, scientists used a high-speed camera to recreate how light reflects off mirrors.

Explosive Boiling

Take a glass of water and heat it in the microwave until the water almost boils. Then take out the glass and put any small object into it, the water will boil when it comes into contact with outside objects.

It's all about the microwave where the water doesn't boil, it's structured. If you heat water on a gas or conventional stove this effect will not happen.

An example of how a phenakistiscope works — a disc with a bunch of figures (drawings), which, as it rotates, creates the illusion of real movement. The effect is based on a feature of the human eye — persistence or inertia of vision.

The magpie uses Archimedes law to reach the coveted water.

The law states that any body completely or partially submerged in a fluid at rest is acted upon by an upward force the magnitude of which is equal to the weight of the fluid displaced by the body.

Triboelectric effect

This experiment demonstrates the appearance of electric charges in the material due to friction.

Thunderball⚡️

It is called a ball of energy floating in the air in the form of a luminous ball.

There is a theory that this phenomenon is a large drop of liquid atomic hydrogen, which is in an excited unstable state.

It arises as a result of electrolysis of water under the influence of fields and lightning currents. The specific weight of this substance is almost equal to the weight of air, which allows the lightning to "float".

A prime example of the importance of correct weighting.

Bernoulli's principle or how planes take off

It states: an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.

As it moves, the wing cuts the air and splits it into two streams. The jets of air flowing around the top of the wing move faster than the lower layer, causing the pressure to drop. Below, under the wing, the pressure will be much higher.

When the speed of the airplane increases, so does the difference between the pressures at the top and the bottom of the wing - the airplane acquires lift. It is the high flow pressure on the earth side that allows a multi-ton aircraft to begin its airborne journey.

Quantum Stealth

This new material refracts light so that a person can only see what is behind it from very close range.

The material reflects light from the ultraviolet to the infrared range, resulting in a distorted background. Thus, objects hidden behind the material become literally invisible from a distance.

Diamagnetic Treadmill

A set of five concentric neodymium magnets, alternating NSNSN, form the treadmill and form the grip field.

Pickles emit a yellow light when electricity passes through them, thanks to their high sodium content.

Underwater glass cutting

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

An intriguing experiment with a samurai sword and a Tesla coil.

The Tesla coil or transformer generates a powerful electrical discharge based on the swinging principle. The device features two coils of wire with current flowing at the same frequency and amplifying the electromagnetic field.

Electrons around the transformer seek out a conductor and escape into it, like lightning discharges into a lightning rod.

Is fire an electrical conductor?

A flame arises from a gaseous substance with hydrogen content, and therefore conducts electricity.

As the temperature rises further, the gas changes to another aggregate state - plasma. Plasma consists of charged particles and conducts electricity magnificently. So the flame conducts current, and the higher the temperature of the flame, the better.
