World's Lightest Solid!

  • Worlds Lightest Solid!


    Aerogels are the world's lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission. The focus of this video is silica aerogels, though graphene aerogels are now technically the lightest.

    At one point Dr. Steven Jones literally held the Guinness World Record for making the lightest aerogel and therefore lightest solid. If you're interested in learning more about aerogels, let me know in the comments as there is a potential trilogy in the works...

    Huge thanks to Dr. Stephen Steiner and the crew at Aerogel Technologies. To find out more or buy your own aerogel sample, check out:

    And thanks to FLIR for loaning us the awesome high definition thermal camera. The footage is amazing!

    Aerogel’s extraordinary properties are due in large part to its structure. Aerogel is a solid but on the nanoscale it has a mesh or sponge-like structure. The struts of this structure are nanoscale, as are the pores at around 20nm across. This makes silica aerogel incredibly light (it was once the lightest solid but has now been superseded by graphene aerogel), transparent and adsorbent.

    An ice-cube sized piece of aerogel has an internal surface area roughly equal to half a football field. Aerogel is used in high end museum cases to regulate humidity. Plus it helps maintain the vacuum on the Mars Insight seismometers - it adsorbs moisture and other outgassed volatiles that come from the spacecraft itself. Proposed uses include as a physical insecticide by ‘drying out insects’ reducing the need for chemical and toxic pesticides.

  • Worlds Roundest Object!


    The world's roundest object helps solve the longest running problem in measurement -- how to define the kilogram.
    Support Veritasium on Patreon:

    A kilogram isn't what it used to be. Literally. The original name for it was the 'grave', proposed in 1793 but it fell victim to the French Revolution like its creator, Lavoisier. So begins the tale of the most unusual SI unit. The kilogram is the only base unit with a prefix in its name, and the only one still defined by a physical artifact, the international prototype kilogram or IPK.

    But the problem with this definition has long been apparent. The IPK doesn't seem to maintain its mass compared to 40 similar cylinders minted at the same time. The goal is therefore to eliminate the kilogram's dependence on a physical object. Two main approaches are being considered to achieve this end: the Avogadro Project and the Watt Balance.

    The Avogadro project aims to redefine Avogadro's constant (currently defined by the kilogram -- the number of atoms in 12 g of carbon-12) and reverse the relationship so that the kilogram is precisely specified by Avogadro's constant. This method required creating the most perfect sphere on Earth. It is made out of a single crystal of silicon 28 atoms. By carefully measuring the diameter, the volume can be precisely specified. Since the atom spacing of silicon is well known, the number of atoms in a sphere can be accurately calculated. This allows for a very precise determination of Avogadro's constant.

    Special thanks to Katie Green, Dr. David Farrant, the CSIRO, and the National Measurment Institute for their help. Thanks also to Nessy Hill for filming and reviewing earlier drafts of this video.

    There is debate as to whether this is truly the roundest object ever created. The Gravity Probe-B rotors are also spherical with very low tolerances such that they may in fact be rounder.

    We Will Solve Your Copyright Issues within 24 Hours

    # Ultra Hydrobhobic Material ( Gentoo )
    Gentoo is the next generation of corrosion-resistant and easy-cleaning coatings. With its combination of high performing abrasion resistance and very low sliding angle, Gentoo excels where other coatings have fallen short

    # Triiodide
    n chemistry, triiodide is usually referred to the triiodide ion, I−
    3. This anion, one of the polyhalogen ions, is composed of three iodine atoms. It is formed by combining aqueous solutions of iodide salts and iodine.

    # Hydrogel
    Hydrogel products constitute a group of polymeric materials, the hydrophilic structure of which renders them capable of holding large amounts of water in their three-dimensional networks. Extensive employment of these products in a number of industrial and environmental areas of application is considered to be of prime importance

    # Nitinol
    Nitinol alloys exhibit two closely related and unique properties: shape memory effect (SME) and superelasticity (SE; also called pseudoelasticity, PE). Shape memory is the ability of nitinol to undergo deformation at one temperature, then recover its original, undeformed shape upon heating above its transformation temperature.

    # Gallium metal
    Gallium is predominantly used in electronics. Gallium arsenide, the primary chemical compound of gallium in electronics, is used in microwave circuits, high-speed switching circuits, and infrared circuits

    # Aerogel
    It looks like frozen smoke. And it's the lightest solid material on the planet. Aerogel insulates space suits, makes tennis rackets stronger and could be used one day to clean up oil spills.

    # Magnetic Thinking Putty !
    Magnetic Thinking Putty takes regular silly putty and turns its awesomeness up to 11. Like any other putty, it can be stretched, bounced, molded, popped, and torn. However, when this putty is in the presence of a magnetic field, it exhibits fascinating properties

    In this video I showcase a really neat high-molecular weight polymer that can self-siphon and pour itself our of a beaker. The reason it can do this is because it can be made to have a very high molecular weight. The solution I used had a MW of 1,000,000. The solution is basically like a molecular sized bowl of string or beads that pull each other out of the beaker once the initial pour has started. Polythylene Glycol is also used as a laxative.

    Before visiting NIST in Washington DC I had no idea machines like this existed. Surely there's an accurate way to measure forces without creating such a huge known force?! Nope. This appears to be the best way, with a stack of 20 x 50,000 lb masses creating a maximum force of 4.45 MN or 1,000,000 pounds of force. I also wouldn't have thought about all the corrections that need applying - for example buoyancy subtracts about 125 pounds from the weight of the stack. Plus the local gravitational field strength must be taken into account. And, the gravitational field varies below grade. All of this must be taken into account in order to limit uncertainty to just five parts per million (.0005%)

    Applied science:
    Do not repeat the experiments shown in this video!
    Hi everyone! Today I would like to tell you about the lightest material on planet Earth - aerogel. As a matter of fact, there exist quite a lot of kinds of aerogel. Some of them consist of metal oxides, for instance aluminium oxides. Others can consist of carbon tubes and graphenes. By the way such an aerographene is a few times lighter than air. However, I can not manage to get this rare material that is why today I am going to show you classic silicon dioxide-based silica aerogel. As you can see this material is very fragile and it crumbled when it was transported in the package. When aerogel crumbles are put on paper sheet, it can be seen that it looks translucent and very light and it is almost invisible against a light background. Aerogel’s density is extremely small about one tenth of a gram per milliliter. The density of aerogels of higher quality can even be compared to that of air. It’s not surprising because aerogel mostly consists of air. To illustrate what aerogel’s structure is like, we can compare it to that of any other gel-like substance. For instance water ball or shampoo. Now try to imagine that all water in such a material has been substituted with air. Roughly speaking, this is what aerogel looks like from inside - small porous material filled with air or another gas. It is quite easy to make aerogel. First, regular silica gel has to be made for instance by mixing together tetraethyl orthosilicate and ammonia solutions in methanol medium. Later such a gel is washed with methanol in order to wash away all traces of water. After that it is sent to a supercritical extractor. Let the complex names not scare you because everything works as simple as a bicycle. Carbon dioxide is pumped under pressure into such an extractor after that the case of of the extractor starts to heat up. When the temperature rises, the liquid carbon dioxide passes to the supercritical state that is becomes something something between liquid and gas. In such a state it can easily wash away methanol from gel substituting it with gas. This is how aerogel forms. If silica gel is just left to dry up in air, this gel will just shrink, turning into a piece of silicon dioxide because of methanol surface tension.

    Aerogel is a material that is 99.8% air. Aerogels have a porous solid network that contains air pockets, with the air pockets taking up the majority of space within the material. The dearth of solid material allows aerogel to be almost weightless.

    #Fact 01 (0:10): Aerogels are the world's lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission.

    #Fact 02 ( 0:23 ):This is Cyclocosmia ricketti, the Chinese hourglass trapdoor spider. nature is truly amazing.

    #Fact 03 (0:36): A number of polyhedral dice made in various materials have survived from the Hellenistic and Roman periods, usually from ancient Egypt when known. Several are in the Egyptian or Greek and Roman collections at the Museum. The icosahedron – 20-sided polyhedron – is frequent.

    Other facts about me!

    I live in Texas and I am still in high school. I am hearing impaired, I lost my hearing at age 3 due to a disease. Luckily, I found a doctor who introduced me to cochlear implants. I had cochlear implant surgery when I was 3. Through my youtube videos, I am trying to show my uniqueness to the world and hope to find people that are like me or part of the deaf culture! I am slowly learning American Sign Language, however, I am not exactly the best at it.

  • Aerogel - Worlds Lightest Solid | Vignesh Rao


    Aerogel’ is a broad term used to talk about an extraordinary group of materials that have been used since the 1960s in space travel, but are now finding uses across a whole range of industries. ‘Aerogel’ is not a specific mineral or material with a set chemical formula-rather, the term is used to encompass all materials with a specific geometrical structure. This structure is an extremely porous, solid foam, with high connectivity between branched structures of a few nanometres across.

  • Aerogel: Worlds lightest solid material!!


    Aerogel is world's lightest solid material which was invented in late 1990s and has a very interesting story behind it. They have been used in several NASA's space mission.

    Aerogel is among the lightest solid materials known to man. Aerogel was first created by Samuel Stephens Kistler in 1931, as a result of a bet with Charles Learned over who could replace the liquid in jellies with gas without causing shrinkage. Itcreated by combining a polymer with a solvent to form a gel, and then removing
    the liquid from the gel and replacing it with air. Aerogel is extremely porous and very low in density. Aerogels are made up of 99.8% air and yet they are solid to the touch. This translucent material is considered one of the finest insulation materials available. What would you use aerogel for? ????:
