The coolest way to wash a bottle

Burning gas inside creates negative pressure, causing the liquid to be drawn into the jar. The number of gas molecules changes as the temperature of the gas decreases.

Magnetic Field vs Mercury.

Interesting demonstration of the interaction of fire with hydrogen.

Crushing of metal pipe under hydraulic press.

Mendocino motor

Electric motor with magnetic levitation of the rotor and powered by solar energy.

Magnet and magnetic slime.

The recipe for making this slime is quite simple. Dissolve a teaspoon of borax in a small amount of water and carefully add the solution to the glue, stirring constantly.

Marangoni effect. If you drop the soap solution into milk or water, this beautiful effect will begin.

It is explained by the fact that water and soap have different surface tensions and the liquid rushes to the place where it is greater.

Interesting optical illusion.

Rear of the jet engine exhaust of a military fighter jet.

Artificial Surfing Wave Maker.

Jetson ONE weighs 40kg and 90kg with batteries

The flight time of this toy is 20 minutes if you weigh 85 kilograms. The maximum horizontal flight speed is 102km/h.

A community of recreational pilots perceives takeoffs as a sport. They hold competitions with specially trained planes competing in short takeoff and landing abilities.

Reflection is a physical process of interaction of waves or particles with a surface, a change in the direction of the wave front at the boundary of two media with different properties, whereby the wave front returns to the medium it came from.

Jamming Mechanics - Mebius Gears.

Even water drainage can be greatly simplified with physics.

The speed of a passenger aircraft is in the range of 600-900 km/h. We are talking about the cruising speed at which the maximum range mode is ensured.

A genius idea that eases the job :)

The Burj Khalifa, like a giant Faraday cage, is the lightning rod of all Dubai
