Restoration of a stadium seat
(6) | 16/06/2021 | Translate: The thermoplastic from which the seats of a stadium are made, is a type of polymer that can be liquefied and formed very easily with temperature. Polymers are not very hospitable in sunlight, from which they are destroyed and weakened, which is why the seats blur and lose their color under sunlight. Thus a thermoplastic polymer can be restored to its original appearance by heating, as color is present in the structure of the material.
The quantum effect in superfluid helium When helium is cooled to a temperature below 2,2 ° K is converted to superfluid, having very strange properties. Superfluid helium can pass easily through tiny pores and cracks, that completely prevents the flow of all other fluids. - Quantum buoyancy The superconductivity is a condition of certain materials that have the ability to conduct electricity with no resistance. This property disappears over a temperature or under a magnetic field and is a quantum state. Here a superconducting material that has very low temperature since it contains liquid nitrogen on the surface, presents this quantum state and has the ability to hover over magnets, without friction.
- The first solar eclipse recorded on video (1900) The magic of a solar eclipse recorded for the first time in video on May 28, 1900 by a famous astronomer, British Nevil Maskelyne, while on a mission of the British Astronomical Society in North Carolina. The eclipse was not easy to be filmed. The Maskelyne had to make a special telescopic adapter for the camera to record the event. This is the only film of Maskelyne we know that has survived until today. The film was restored by the British Film Institute.
- A fireproof super-material that you can make in the kitchen by Ben, He shows us how he managed to create a highly refractory material that can withstand high temperatures. His inspiration was the Starlite, a material invented in the 1980s by Maurice Ward, but no one ever learned the recipe posthumously.
- Stray dog does ride the bus On July 29, 2018 in Santiago, Chile, A stray dog came in on a bus behind a passenger. He sat quietly in one of the seats and enjoyed the calm ride. The bus driver is not turned away because he says he loves animals and was out cold. Currently in Santiago cold weather, around 7-10 ° C.
- The places for sports fans punished In a stadium, a man has been sitting a few seats that have become superfluous, well located just behind a wall.
- induction iron A knife is immediately heated to incandescent temperature, using induction. The induction Fusion is an application of Faraday's law, where heat is transferred to a conductive material through a magnetic field without the presence of physical contact. The changing magnetic flux passing through the conductive material causes the current flow in this, which is responsible for the heating of.
- Quantum buoyancy in a Möbius strip The strip or tape of blamable (Möbius Strip) is a particularly simple construction showing that two surfaces can be converted into a single. On such a strip, Students constructed a quantum buoyancy system, wherein a superconducting material having a very low temperature (dipped in liquid nitrogen), It has the ability to hover over magnets frictionless.
- The new carpet in court Russia A man in Russia shows us the high quality material from which is made the new carpet on the pitch.
- The new windscreen wiper system of Mercedes The new windscreen wiper system of Magic called Vision Control Mercedes, It works according to the outside temperature and automatically adjusts the wash liquid quantity with the surrounding circumstances. The company has released this video to introduce the new system. It would also be useful to give us some information on the prices of spare parts.
- Car wipers at-20 °C Watch what happens when the bitter cold in the city Novosibirsk Russia immediately freezes the wet cleaning of windscreens in this car. Temperatures in the area reached the 20-°C last week.
- The digital simulation of materials of Disney, to create animation The Studio Disney cartoon creation, shows us that can simulate digital natural motion of various liquids and solids, which melt or solidify.
- Spent with her car from an open drawbridge Monday, September 29 in the city Tisno Croatia, a woman in a yellow Peugeot crossing a drawbridge, When this is open. The bridge rose by 2,5 meters, 47chroni but the driver managed to get moving at 80 km / h, without having seen the Red Lantern. The bridge keeper did signal the woman to stop, but she ignored him and stepped on the accelerator. In the passenger seat was the teenage daughter of, While the clash activated airbags and protected from injuries. The woman told police that he was blinded by the Sun. Eventually fined 30 euros for dangerous driving.
- An unusual connector The British research analyst Andy Elliott us demonstrates the unique qualities of a fastener that is manufactured from alloy nitinolis (nickel-titanium). The "magic trick" by nitinoli is based on temperature change, which makes it a very useful material in the field of medicine.
- Gallium Gallium is a fusible metal that liquefies slightly above room temperature and melts easily in hand. Also an interesting capacity is that can decompose the molecular structure of aluminum very quickly and to destroy. Therefore the international air transport association ranked the gallium in corrosive materials, and prohibits all passengers to carry with them when they travel by plane Gallium.
