The Science of How Slime Works

You know about slime. Youve either made it as a science project or blown the natural version out of your nose. Do you know what makes slime different from a regular liquid? Heres a look at the science of what slime is, how it forms, and its special properties. What Is Slime? Slime flows like a liquid, but unlike familiar liquids (e.g., oil, water), its ability to flow, or viscosity, is not constant. So its a fluid, but not a regular liquid. Scientists call a material that changes viscosity a non-Newtonian fluid. The technical explanation is that slime is a fluid that changes its ability to resist deformation according to shear or tensile stress. What this means is, when you pour slime or let it ooze through your fingers, it has a low viscosity and flows like a thick liquid. When you squeeze a non-Newtonian slime, like oobleck, or pound it with your fist, it feels hard, like a wet solid. This is because applying stress squeezes the particles in the slime together, making it hard for them to slide against each other. Most types of slime are also examples of polymers. Polymers are molecules made by linking together chains of subunits. Examples A natural form of slime is mucous, which consists mainly of water, the glycoprotein mucin, and salts. Water is the main ingredient in some types of human-made slime, too. The classic science project slime recipe mixes glue, borax, and water. Oobleck is a mixture of starch and water. Other types of slime are mainly oils rather than water. Examples include Silly Putty and electroactive slime. How It Works The specifics of how a type of slime works depends on its chemical composition, but the basic explanation is that chemicals are mixed to form polymers. The polymers act as a net, with molecules sliding against each other. For a specific example, consider the chemical reactions that produce classic glue-and-borax slime: Two solutions are combined to make classic slime. One is diluted school glue, or polyvinyl alcohol in water. The other solution is borax (Na2B4O7.10H2O) in water.Borax dissolves in water into sodium ions, Na, and tetraborate ions.The tetraborate ions react with water to produce the OH- ion and boric acid:B4O72-(aq) 7 H2O — 4 H3BO3(aq) 2 OH-(aq)Boric acid reacts with water to form borate ions:H3BO3(aq) 2 H2O — B(OH)4-(aq) H3O(aq)Hydrogen bonds form between the borate ion and the OH groups of the polyvinyl alcohol molecules from the glue, linking them together to form a new polymer: slime. The cross-linked polyvinyl alcohol traps a lot of water, so slime is wet. You can adjust the consistency of slime by controlling the ratio of glue to borax. If you have an excess of diluted glue compared with a borax solution, youll limit the number of cross-links that can form and get a more fluid slime. You can also adjust the recipe by limiting the amount of water that you use. For example, you could mix the borax solution directly with glue, producing a very stiff slime.

The History of African Americans in Film Essay - 2066 Words

Minstrel shows were developed in the 1840s and reached its peak after the Civil War. They managed to remain popular into the early 1900s. The Minstrel shows were shows in which white performers would paint their faces black and act the role of an African American. This was called black facing. The minstrel show evolved from two types of entertainment popular in America before 1830: the impersonation of blacks given by white actors between acts of plays or during circuses, and the performances of black musicians who sang, with banjo accompaniment, in city streets. The father of American minstrelsy was Thomas Dartmouth Daddy Rice, who between 1828 and 1831 developed a song-and-dance routine in which he impersonated an old, crippled†¦show more content†¦Tambo) at one end and a performer on the bone castanets (Mr. Bones) at the other, the singing of songs with harmonized choruses, the exchange of jokes between the endmen and the performer in the center seat (Mr. Interlocutor), a nd the introduction of special variety acts at the conclusion of the bill. Though many of these shows claimed that these were true African American songs that had been brought back by people who had observed plantation slaves, this wasn?t necessarily true. For example one of the more common songs such as ?Jim Crow?by Thomas Rice was simply inspired by a crippled African American that Rice had seen dancing and singing a song with the chorus of ?Wheel about, an turn about, an do jis so, Ebry time I wheel about, I jump Jim Crow.? Many people were lead to believe that this was how every African American sang and danced and failed to realize that this was simply the way one man did it. Actual African American actors were rare at the time. There were only a few African Americans that actually appeared on stage and those who did only had minor roles such as servants or shoe shiners. This was mainly because the world was used to African Americans being slaves doing jobs such as these and pe ople weren?t ready to accept African Americans as equals yet. There had however been several attempts of African American stage performance such as New York?s African Grove theater.

Classical vs. Modern music Essay Example For Students

Classical vs. Modern music Essay Classical Music vs.. Modern Music Classical and Modern music have many differences as well as similarities. In this paper, I compare classical and modern-day music through a means of artists, performances, and specific pieces. Although modern and classical music have different meanings, for example classical music back in the early 19th century was only played for the rich and royal and took some composers multiple months to compose, while modern music can be created in Just hours with electronic sounds instead of musical instruments and listened to by anyone, compositions of each can hare similar beats, rhythms, and melodies that connect them to each other. Wolfgang Amadeus Mozart was born on January 27, 1756, in Syllabus, Austria. He was born to an overbearing and ambitious father, Leopold, who was more than anxious to exploit his sons amazing musical gifts. Mozart began composing at an early age, and he began touring around the same time. Throughout his life, Mozart made many enemies, many his own fault, through his naive arrogance and harsh critique of his musical colleagues. He worked anxiously, composing symphonies and operas, as well as touring constantly. Mozart died of overwork and kidney failure on the 5th of December 1791 while still ironically at work on the Requiem Mass for an unknown client. Though he lived for a relatively short time, Mozart prolific musical career, in which he composed hundreds of musical works, gained him a place among the all time greatest composers. Henry Festivities was born in 1820 in Verviers, Belgium, a fertile ground for violinists. He had his first lessons from his father, a weaver and amateur violin-maker and player. Festivities made his first public appearance as a violinist at the age of six, playing a concerto by Rode. In 1836, Festivities wrote his first violin concerto, the Concerto No. 2 in F sharp minor, published as Opus 19. In 1843 and 1844 he toured America and during that time, he wrote his Concerto No. 3, Opus 25, a work now as a great poem rather than a concerto, influenced by Beethovens Violin Concerto. In his later years, Festivities devoted much of his time to teaching, but suffered a stroke in 1871, making virtuoso playing impossible. Afterwards, in 1877 he resumed teaching and conducting in Paris. Illness led finally to his resignation in 1879, but he continued to compose, completing his Concerto No. In G Major, Opus 47, and soon thereafter Concerto No. 7 in A minor, Opus 49. He died in 1881 and was buried in his hometown of Verviers. I was able to get old of a recorded version of Mostly Mozart Festival, Avery Fisher Hall, Lincoln Center. This musical performance included three works from Wolfgang Amadeus Mozart Symphony No. 32 in G, K. 318, Piano Concerto in D minor, K. 466 and Symphony No. 35 in D, K. 385 (Huffier) and one from Henry Festivities Violin Concerto No. 5. Emmanuel Ukraine conducted the performance, with featured soloists Joshua Bell (Festivities violin concerto) and Stewart Goodyear (Mozart piano ancestor). A full orchestra performed the symphonies. Overall, the Mostly Mozart Festival was a tremendously enjoyable experience to watch. The qualities that define the works of Mozart are often the same as those that are used to describe those of the classical period of music, from his smooth melodies and flowing rhythm, to his Classical vs.. Modern music By Halley-Guerrilla the most defining principles of the style of Mozart is the connection to nature and God, and the seeming oneness and harmony that can be achieved simply by listening while the melodies take you too higher plane of thought. The most enjoyable piece from the performance was Allegro, from Mozart Concerto in Dim. .u7cf57eb82f4501bf81fe0564718206af , .u7cf57eb82f4501bf81fe0564718206af .postImageUrl , .u7cf57eb82f4501bf81fe0564718206af .centered-text-area { min-height: 80px; position: relative; } .u7cf57eb82f4501bf81fe0564718206af , .u7cf57eb82f4501bf81fe0564718206af:hover , .u7cf57eb82f4501bf81fe0564718206af:visited , .u7cf57eb82f4501bf81fe0564718206af:active { border:0!important; } .u7cf57eb82f4501bf81fe0564718206af .clearfix:after { content: ""; display: table; clear: both; } .u7cf57eb82f4501bf81fe0564718206af { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u7cf57eb82f4501bf81fe0564718206af:active , .u7cf57eb82f4501bf81fe0564718206af:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u7cf57eb82f4501bf81fe0564718206af .centered-text-area { width: 100%; position: relative ; } .u7cf57eb82f4501bf81fe0564718206af .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u7cf57eb82f4501bf81fe0564718206af .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u7cf57eb82f4501bf81fe0564718206af .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u7cf57eb82f4501bf81fe0564718206af:hover .ctaButton { background-color: #34495E!important; } .u7cf57eb82f4501bf81fe0564718206af .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u7cf57eb82f4501bf81fe0564718206af .u7cf57eb82f4501bf81fe0564718206af-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u7cf57eb82f4501bf81fe0564718206af:after { content: ""; display: block; clear: both; } READ: The Hudson Project Musical Festival EssayIt is unbelievable the way he crafted and rhythmically shaped this piece. One of the most outstanding elements of this piece is the harmony created between the piano and the strings as they accompany each other with seeming perfection. The resulting experience is exciting to say the least. Accentuating the piece even more was the performance by the virtuoso pianist, Stewart Goodyear. Although still in his early twenties, this musical genius has already far surpassed many of his interpolates and his solos are breathtaking, as he routinely improvises and takes even the most perfect piece to new heights. In addition to Mozart, the performance also included a Violin concerto by Henry Festivities, a romantic era violin virtuoso, with Joshua Bell performing on the violin. Festivities uses many of the attributes of the romantic era, such as an incredible freedom of movement and rubout time, which leaves much up to interpretation by the performer. Perhaps the most exhilarating part of this piece was the solo performance of the violin, as the incredible speed along with dramatic dynamic mess to flow in such a way that would not seem possible. It would be logical to assume that the other people who watched this performance shared this opinion, as response was very powerful, and lasted for some time. In the more modern era, Claude-Michel Schoenberg was born in Paris in 1944 of Hungarian parents; he began his career as a singer, writer and producer of popular songs. He wrote the musical score of La Revolution Praises in 1973, Less Mis ©rabbles in 1980 and Miss Saigon minion. Since then he has also supervised overseas productions of Less Mis ©rabbles ND Miss Saigon and co-produced several international cast albums of his shows. He is currently working on a new production of his last musical Martin Gruyere. He lives in Paris with his wife and two children. Herbert Krimmer was born in South Africa, where he began his Journalistic career writing the commentary for a weekly movie newsreel. In 1960 he Joined the staff of the Daily Express and later became its chief drama critic, a post he held for 18 years, covering about 3000 first nights. From 1979 to 1987 he wrote television criticism for the Daily Mail, winning two national press awards. Krimmer wrote the book and lyrics of the West End musical Our Man Creighton, which starred Kenneth More and Emollient Martin, and the lyrics for The four Musketeers. For his Less Mis ©rabbles lyrics he received Tony and Grammar awards. In 1996 he was elected an Honorary Doctor of Letters at Richmond College. I was lucky enough to see the Broadway performance of Less Mis ©rabbles in New York a couple years back. Mis ©rabbles, Imperial Theater, Broadway, perhaps the most popular and best loved musical on Broadway, Less Mis ©rabbles contains some of the most defining elements of the modern musical. The composer is able to convey many moods, from Joyous to sad, as well as provide a perfect platform for the lyrics, which comprise almost all of the spoken language of the musical. The moods are perhaps the most noticeable element of the musical, for example, the feeling end of the scale, there is the hostile emptiness felt in On My Own, a song about unknown and one-sided love. There is also a very noticeable flow to the entire performance, one that seems to be moving along and carrying the story. It is very instinctual and subconscious at the same time, providing for a very pleasant experience altogether. Working hand in hand with the instrumental aspect, the lyrics of Less Mis ©rabbles lend themselves wholly to the mood of the pieces. From Can You Hear the People Sing, a march drumming up support for the upcoming revolution, to A Little Fall of Rain, in which a dying Opinion professes her hidden love, the lyrics portray perfectly the mood and complement the music wholly. The success of these portrayals is reflected by the response of the audience, which was energetic and highly appreciative. When comparing the two performances, it is important to notice the influence that one may have had on another. .ua42a63a79275d63b3430d68358f68dc5 , .ua42a63a79275d63b3430d68358f68dc5 .postImageUrl , .ua42a63a79275d63b3430d68358f68dc5 .centered-text-area { min-height: 80px; position: relative; } .ua42a63a79275d63b3430d68358f68dc5 , .ua42a63a79275d63b3430d68358f68dc5:hover , .ua42a63a79275d63b3430d68358f68dc5:visited , .ua42a63a79275d63b3430d68358f68dc5:active { border:0!important; } .ua42a63a79275d63b3430d68358f68dc5 .clearfix:after { content: ""; display: table; clear: both; } .ua42a63a79275d63b3430d68358f68dc5 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ua42a63a79275d63b3430d68358f68dc5:active , .ua42a63a79275d63b3430d68358f68dc5:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ua42a63a79275d63b3430d68358f68dc5 .centered-text-area { width: 100%; position: relative ; } .ua42a63a79275d63b3430d68358f68dc5 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ua42a63a79275d63b3430d68358f68dc5 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ua42a63a79275d63b3430d68358f68dc5 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ua42a63a79275d63b3430d68358f68dc5:hover .ctaButton { background-color: #34495E!important; } .ua42a63a79275d63b3430d68358f68dc5 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ua42a63a79275d63b3430d68358f68dc5 .ua42a63a79275d63b3430d68358f68dc5-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ua42a63a79275d63b3430d68358f68dc5:after { content: ""; display: block; clear: both; } READ: Racial Issues and Music EssayFor example, the music of Wolfgang Amadeus Mozart had a terrific impact on the musical world, and later, practically every musician is influenced in some way by his input. Therefore, it would be logical to assume that Schoenberg was influenced by the works of Mozart. Though they vary in elements such as instruments as well as words, many have much in common, such as structure, which follows a basic formula of repeating melodies and reprisals. They also share much in the sense of flow, tones, and dynamics. The effect of both performances on me as a listener was a good one. Not only have both exposed me to arioso sides of the musical world, they have also increased my knowledge and understanding of music, as well as its roots and the relationships between different genres. The final facts are not only relevant because I thoroughly enjoyed both performances, but also because I was experiencing a diversity of styles and compositions. Through exposure to different forms of musical interpretation, it is possible to understand better how music evolves and how it becomes part of our culture and shapes the way we live, as well as how it is used as a form of communication, and helps us better understand ourselves.

PG case study free essay sample

Brand equity can be defined as the added value awarded on products and services. It may be reflected in the way consumers think, feel, and act with respect to the brand, as well as in the prices, market share, and profitability the brand commands (Kotler Keller, 2009). Additionally, Brand equity is an intangible asset built up by a company overtime by building awareness, having a well-known name or a clear identity, consistent communications, marketing to the consumer, acting socially responsible, and spending on advertising and promoting the brand. Procter Gamble (PG) has been known to be one of the most skillful marketers of consumer packaged goods and also the company holds one of the most powerful groups of trusted brands. Developing brand equity is vital as it allows companies to more effectively engage with their customer base in such a way that drives brand loyalty, allowing the business to grow further. We will write a custom essay sample on PG case study or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page PG energies brand loyalty due to its numerous capabilities and philosophies. Some of the capabilities are huge market research and intelligence gathering, active product innovation, brand management system and also quality strategy in which the company designs and improve products of high quality in ways that matter to consumers. Therefore, developing brand equity is important because the products associated with the brand command a premium price in the market and is perceived to be higher quality when compared to the similar generic unbranded products. Brand equity also offers competitive advantages by reducing the marketing costs to companies that enjoy high â€Å"Brand Equity† such as PG as a result of high brand awareness and loyalty and thus enhances their earnings. 2. What are the key factors when considering a brand strategy? A branding strategy categorizes which brand elements a company chooses to apply across the various products it sells (Kotler Keller, 2009). Firstly, market size can be considered as a factor when considering a brand strategy. When the market size for the product is large or small, the company can choose to use product branding strategy or existing brand respectively. Another factor can be innovativeness and technology; entirely new product category or a major technology breakthrough presents special problems in branding. The company has to make sure that the success of the product brings recognition to the company. PG is an active product innovator, devotes about $2 billion every year to RD and part of its innovation process is to develop brands that offer new consumer benefits. Competitive situations could be another factor. When the competition is fierce, there is a huge need to highly differentiate the product offering. This requires communicating specific consumer benefit and the brands personality dimensions. Furthermore, marketing costs is another factor to consider. PG’s purpose for internationalizing the brands is economies of scale and scope. What is successful in one country is simply brought to another. Each single brand does not necessarily exist in all markets. For instance, the cost advantage with PG’s type of branding strategy, which is product branding, is as mentioned previously economies of scale and scope.
