Paint with hydrographic printing
(7) | 02/08/2022 | Translate: 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.
Hydrographic printing Hydrographic printing is a method of applying printed designs in 3D objects. Can be used on metal, plastic, glass, wood, and various other materials. 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 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.
- Why are placed 96.000.000 balls into a drinking water tank; The Veritasium channel visited the drinking water tank in Los Angeles to see why it has been covered by 96 million black plastic balls. The balls are made of high density polyethylene (HDPE), which is less dense than water, so as to float on the surface of the tank even if dissolved. They have a diameter of 10 cm and containing about 210ml water. The primary reasons the tank is to prevent sunlight from entering the water and cause a chemical reaction that converts the bromine in carcinogenic bromate.
- petrol tank emerging from the ground A reservoir 90.000 liter emerges from the ground, as a submarine returns to the water surface, a petrol station. This phenomenon is due to the large amount of water in the subsoil and the low fuel level in the tank.
- A tarantula walks on water The hairs on the tarantula's legs trap air, and allow her to stand on the surface of the water. Tarantulas have difficulty moving in water so they don't do it often, but they are known to cross bodies of water when they need to escape a predator.
- Spectacular collapse of a part of the Perito Moreno glacier In Argentina's Los Glaciares National Park, Spectacular footage has been captured of a huge chunk of the Perito Moreno glacier breaking off and emerging from the surface of the water, gradually revealing its submerged part. The height of the Perito Moreno glacier is 170 meters, of which 74 are above the surface, while the rest are under the waters of Lake Argentino. With a length of 5 kilometers, the glacier is slowly advancing into the lake facing the Magellan Peninsula. When he reaches the opposite bank, divides the lake in two, then acting as a natural barrier. The water level of Lake Argentino then rises to 30 meters and begins to cut into the glacier. As it becomes less durable, it buckles under the pressure.
- Beautifying wood with fire Yakisugi is a traditional Japanese wood surface treatment technique, using fire.
- Playing hopscotch on a slippery surface A group of friends play hopscotch by different rules, on a slippery plastic mat. The player should carry a basin of water and empty it at the goal.
- Water tank collapses and rolls down a slope (Brazil) In the Sao Paulo area, a cylindrical water tank collapses, it rolls down a hillside and completely flattens a few cars in its path.
- 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.
- They poured color into a waterfall for their party In a video shot on September 25, 2022, a couple from Tangará da Serra, Brazil decided to dye the water of a waterfall blue during a gender reveal party for the upcoming birth of their baby. The video was posted on Instagram, but it caused a lot of outrage from users before it was finally deleted. The Minister of Environment of Mato Grosso (SEMA) announced the opening of an investigation into the pair to determine whether products used to dye the waterfall's water had contaminated the source, as the Queima Pé River is an important source of water for the region.
- 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.
- Bowling On a farm, a cow throws its roommate into the water tank. A breeder will come a little later to help her.
- Rail welding Although in the past the rails had to have a gap between them to cope with temperature expansion/contraction, this technique is no longer applied to high-speed trains. The rails are welded together for several kilometers, and then heated to a high temperature to fully expand. Rail fasteners use very high clamping force, and so the contraction is much less. A second technique is the expansion joint, which may be different: it is no longer a mere gap, but a smooth joint where the two rails are side by side and when they grow or shrink in length they can slide next to each other.
- 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.
