Motionless water
(16) | 12/10/2018 | Translate: In this video we see an example of laminar flow (Laminar Flow) of the water, which in combination with the camera gives the impression that it is stationary. The laminar flow of a fluid is the situation where the fluid flows in parallel lines and all the particles passing through a point having the same speed. The flow rate exceeds the frames / second that can record the camera, and so the water in the video seems completely static.
Perfect laminar water flow from a spring In Val Camonica valley in Lombardy, Italy, a source puts water in laminar flow, shown completely static when recorded in video. The laminar flow of a fluid is the situation where the fluid flows in parallel lines and all the particles passing through a point having the same speed. The flow rate exceeds the frames / second that can record the camera, and so the water in the video seems completely static.- laminar flow Emptying a pool, a man observed a rare phenomenon in the water flow. At first glance, one might think that the flow of water is frozen, but when the man puts his hand, it appears that water normally flowing. This phenomenon is called laminar or parallel flow, and occurs when the fluid flows parallel to the axis of the conductor lines, while all particles passing through a point having the same speed.
- The shutter of a camera 10.000 fps The Horrible Gawain shows us how it moves the shutter of a DSLR camera (digital SLR) and recorded at 10.000 frames per second. The shutter of the camera controls the light that enters for the creation of photography. In an environment with little light, the shutter must remain open for a longer time in order to capture the maximum light and vice versa. This is called shutter speed or "exposure time".
- A lightning to 7000 fps A lightning recorded by a high speed camera 7.000 frames/sec
- Experiment: how to avoid water from cars in the rain The TreeMan channel from China, discovered that if you hold a brick in your hands when you are near the road, drivers will slow down and not run you over.
- Lightning fast checkout At the checkout of a Wal Mart supermarket in the United States, an employee works at an irritatingly slow pace.
- A factory worker tries to murder a colleague (China) In a factory in China, an employee tries to strangle a colleague in cold blood among other employees. The scene was captured by a security camera on a production line. A man approaches and tries to strangle his colleague by tightening a rope around his neck without anyone reacting, thinking it was a joke. After several seconds, an employee in a pink uniform (who appears to be a superior), asks another to intervene. And it is from that moment that several workers will react by preventing the worst.
- Timing problems in a Zumba class A woman participates in a Zumba class but finds it difficult to coordinate her movements with those of the other participants. He doesn't move in rhythm and takes a completely random number of steps throughout the choreography, constantly leaving the shot of the camera filming the session.
- Cavitation in a glass water bottle Cavitation in a glass water bottle being hit by a hammer. Cavitation is a phenomenon in which the static pressure of a liquid drops below the boiling pressure of the liquid, leading to the formation of small vapor-filled cavities within the liquid. At higher pressure, these cavities collapse and can create shock waves that can damage the container. Video in slow motion at 82.000 frames per second from them "The Slow Mo Guys".
- Hydrofoil bike After 5 years of development, the hydrofoil bike of the Manta5 company from New Zealand is on sale. It is a bicycle that works like hydrofoil sea boats, having fins called hydrofoils. Above a certain speed, the bike leaves the surface of the water resulting in zero friction.
- Autonomous machine gun for chickens User da.hell.is.this used an old smartphone and a raspberry pi 3b+ to program and build an automatic water sprinkler that chases chickens away from his yard. AI recognizes chickens from the camera, marks and pulls the trigger when a chicken is spotted.
- The hydrophobic properties of cocoa Cocoa powder is a hydrophobic substance, which means that water cannot enter it when it is in a large amount. When mixed, it can apparently be mixed in liquids, but when stationary the liquids flow over the powder as with any other hydrophobic substance.
- The perfect angle for the camera During the warm-up before a football match the camera will capture a funny scene that will be made even better by the shooting angle. A water sprinkler will suddenly start, drenching a football player. Because of the shooting angle, water appears to be coming out of a teammate's rear.
- Art in slow motion The interaction of liquids with various objects, as captured by a high-speed camera in slow motion.
- Kit that turns a bicycle into an electric one Gursaurabh Singh from India, made a kit that adapts to bicycles and converts them into electric ones. The battery is charged to 50% with 20 minutes pedal, reaches speeds of 25 to 40 km / h, withstands mud, water and fire, and also has USB charging ports.
