Static flow
(6) | 13/04/2012 | An incredible illusion is created when the frequency of sound waves and water flow is synchronized with the framerate (images per second) a camcorder. The water looks like it's static and drops to levitate.
The Leidenfrost effect When a surface is heated to above 200 ° C and a drop of water in contact with it, the evaporation of the layer at the base of the drop makes hovering, While the steam layer between the style and the material acts as a thermal insulator, not allowing the drop to evaporate immediately. Two students at the University of Bath in m. Britain, built a labyrinth that works with this phenomenon and initiates the drops in specific directions.- Water and sound An experiment where the frequency of sound waves and water flow are synchronized with the framerate of a camcorder, creating this incredible optical illusion.
- Acoustic buoyancy At Argonne National Laboratory in Chicago, scientists found a way to keep on swinging small drops of liquid substances, with the help of sound waves. This way you will be able to study the effect and efficacy of many drugs in the human body.

- Refreshment on a hot spoon TikToker from the channel @flames_vs performs an experiment by pouring a few drops of Sprite on a hot spoon. The spoon is placed over the flame of a burner. The water in the Sprite evaporates leaving only the sugar, which then turns into candy.
- Swallowfishes and their predators The swallow fishes, are fish of the Exocoetidae family that have developed fins on their gills, which give them the possibility to be ejected and suspended over the water several meters. This ability of theirs can make them more agile, but at the same time makes them vulnerable above and below the surface of the water - since above they are chased by the frigate birds (Frigate), and from below fish hunters (Coryphaena hippurus). Excerpt from the documentary "The Hunt" by BBC.
- Snail vs. Drop A snail collides with a drop of water.
- Waterproof drone that flies and submerges in water The Mirs-X is a quadcopter that flies like a standard drone, but can also submerge and move through water, using the same four propellers. Researchers at the Chinese University of Hong Kong designed the prototype to hover for six minutes in the air or stay underwater for about 40 minutes.
- This water is not real In a film studio, a floor and a vertical screen create the illusion of a real beach.
- Rainbow on a cloud On August 21, 2022, residents of the city of Haikou in Hainan Province in China were able to observe an iridescent cloud. Iridescent clouds are a diffraction phenomenon caused by small water droplets or small ice crystals scattering individual light. The light refracts giving the cloud a colored appearance.
- Projection over a fountain At LaGuardia Airport in New York, there is a spectacular fountain. Water falls from two rings to create one "Curtain", in which images are projected with a projector. Extra, 450 nozzles open and close individually to create shapes in the water.
- Paint with hydrographic printing The technique of painting objects with hydrographic printing: PVOH film printed with the image of the artwork to be transferred, and then placed on the surface of a water tank. A chemical is sprayed onto the membrane to help weld, and then the object sinks into the tank until the film to bind on it.
- A drop of water falls in slow motion The drop of a drop on a surface of water in slow motion (5000 fps). The drop bounces off the surface and becomes smaller and smaller.
- A technology for real holograms In 2019 at the InteractLab research center at the University of Sussex, Researchers have developed a hologram that uses a polystyrene bead, which is suspended by means of an array of speakers emitting ultrasound. The bead is illuminated with an LED light projection, and moves so fast that it creates images.
- A Bryde's whale eats fish Wildlife photographer Bertie Gregory, captures stunning images of a Bryde's whale feeding in the Gulf of Thailand. The whale opens its mouth on the surface of the water while remaining motionless and trapping thousands of fish.
