Can You Shatter a Glass with Your Voice

Fact or Fiction?: You can shatter a glass using just your voice.Fact. If you generate a sound, with your voice or another instrument that matches the resonant frequency of the glass, you produce constructive interference, increasing the vibration of the glass. If the vibration exceeds the strength of the bonds holding the molecules together, youll shatter the glass. This is simple physics -- easy to understand, but harder to actually do. Is it possible? Yes! Mythbusters actually covered this in one of their episodes and made a YouTube video of a singer shattering a wine glass. While a crystal wine glass is used, its a rock singer who accomplishes the feat, proving you dont have to be an opera singer to do it. You just have to hit the right pitch and you have to be loud. If you dont have a loud voice, you can use an amplifier. Shatter a Glass With Your Voice Ready to give it a try? Heres what you do: Put on safety glasses. Youre going to shatter a glass and youll likely have your face close to it when it breaks. Minimize the risk of getting cut!If youre using a microphone and amplifier, its a good idea to wear ear protection and turn the amplifier away from you.Tap a crystal glass or rub a damp finger along the rim of the glass to hear its pitch. Wine glasses work particularly well because they usually consist of thin glass.Sing an ah sound at the same pitch as the glass. If you arent using a microphone, youll probably need the glass close to your mouth since the intensity of the sound energy diminishes with distance.Increase the volume and duration of the sound until the glass shatters. Be aware, it may take multiple tries, plus some glasses are much easier to shatter than others!Carefully dispose of the broken glass. Tips for Success If you arent sure the glass is vibrating or that you have the right pitch, you can place a straw in the glass. Slide your pitch up and down until you see the straw shake. That is the pitch you want!While they are more fragile and its easier to match the precise pitch of a crystal glass, there is some evidence its easier to break ordinary cheap glass. Crystal glasses require 100 decibels to shatter because they are... well... crystal. Ordinary glass is an amorphous solid that may be easier to disrupt (80-90 decibels). Dont discard a glass for your project just because it isnt crystal.If you cant match the pitch of the glass, be aware you can break the glass by singing an octave lower or higher than its frequency.

The Symbolism Of Ophelia s Hamlet - 1500 Words

Prescribed Question: How could the text be read and interpreted differently by two different readers? Text Analyzed: Shakespeare’s Hamlet Part of the Course to Which the Text Corresponds to: Part 4 Thesis: In Shakespeare’s tragedy, Hamlet, Ophelia’s role would be interpreted as a plot device by a modern English woman and as a victim by an Elizabethan woman. This would occur because of their understanding of the symbolism of Ophelia’s actions in madness, the context surrounding Hamlet’s view of her, and their characterization of Ophelia. Argument 1 Topic Sentence: The two readers would interpret the symbolism of Ophelia’s actions in madness differently according to their understanding of Elizabethan customs. Evidence/Analysis Summary: â€Å"There’s fennel for you, and columbines. There’s rue for you. And here’s some for me [†¦] I would give you some violets, but they all withered when my father died.† (IV:v:178-184) Modern woman: Surface interpretation- no concept of the flowers, which provide context for her purpose. This removes Ophelia’s depth as a character, and merely portrays her as crazy and a plot device to reunite the cast. Elizabethan woman: Would grasp the context, and understand the value of the flowers, and Ophelia’s understanding of the events at Elsinore. They would understand her role as being a victim of the evil in the court.

Master Harold Differing Influences On Fugard Essay Example For Students

Master Harold: Differing Influences On Fugard Essay Athol Fugards drama, Master Harold . . . And The Boys, waswritten during a time of great conflict in South Africa, where hewas raised. Fugard was torn between his mother, who wasAfrikaaner, (1291) and his father, who was of English decent(1291). These differing influences caused Fugard to use thediscussions between Sam and Hally to demonstrate the religious,racial, and political tensions of his lifetime in South Africa. The discussion between Sam and Hally about who was a man ofmagnitude (1300) represents the religious tensions of Fugardslifetime in South Africa between the growing belief in evolutionand Jesus Christs teaching of Creation. Hally says that CharlesDarwin was a man of magnitude, (1300) because he was somebodywho benefited all mankind (1301). He admires Darwin for hisTheory of Evolution (1301), which according to Hally, proveswhere we come from and what it all means (1301). Sam totallydisagrees with Darwins Theory of Evolution (1301) becauseevolution is in contrast to the Bibles teaching on Creationism,and he says that just because it is in a book it does not mean got to believe it (1301). Sam believes that JesusChrist (1302) was a man of magnitude (1300). Hally isobviously against Sams suggestion of Jesus Christ, because Hallymakes it clear that he is an atheist (1303). This disagreementbetween Sam and Hally is really just an example of the religioustensions in South Africa during Fuga rds lifetime between theTheory of Evolution, (1301) which was becoming more accepted,and Christianity, which was taught by Jesus Christ. A second discussion between Sam and Hally that occurs after Hallylearns that his father has gone home demonstrates the racialtensions of Fugards lifetime in South Africa. When Sam startslecturing Hally about how he treats his father, Hally becomesangry and tells Sam that he is treading on dangerous ground(1321). Hally also tells Sam that his mother is right(1322)about warning about allowing you to get to familiar(1322). The climax of the argument is when Hally tells Sam thathe is only a servant (1322). This is the first noticeablestatement that Hally makes that demonstrates the racial tensionsexperienced in South Africa. The next racial statement Hallymakes is when he tells Sam that his father is his boss becausehes a white man and thats good enough for (1322). Hally then takes things even further by commanding Sam to startcalling Master Harold (1323). Hally tells Sam that if hedoesnt follow this command that he might just lose job(1323). Hally really makes matters worse when he tells Sam hisfathers favorite joke. His father would ask Hally, Its notfair, is it, Hally (1323)? Then Hally would ask, What, chum(1323)? Then his father would say, A niggers arse (1323). Another example of the racial tensions during the argument ismade when Sam points out that when Hallys father got drunk at abar, that Hally had to go in first . . . to ask permission(1325) for Sam to be able to go in to get his father. A finaland the most noticeable example of the racial tensions in SouthAfrica is made by Sam when he informs Hally about the reason whyhe didnt stay with him the day they flew the kite. Sam tellsHally that the bench he had sat on was a Whites Only (1325)bench and Sam wasnt allowed to sit on it.All of theseexamples are used to represent the racial tensions that werepresent in Fugards lifetime in South Africa. .uebb95ef1a784721e03cd07ea72909441 , .uebb95ef1a784721e03cd07ea72909441 .postImageUrl , .uebb95ef1a784721e03cd07ea72909441 .centered-text-area { min-height: 80px; position: relative; } .uebb95ef1a784721e03cd07ea72909441 , .uebb95ef1a784721e03cd07ea72909441:hover , .uebb95ef1a784721e03cd07ea72909441:visited , .uebb95ef1a784721e03cd07ea72909441:active { border:0!important; } .uebb95ef1a784721e03cd07ea72909441 .clearfix:after { content: ""; display: table; clear: both; } .uebb95ef1a784721e03cd07ea72909441 { 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; } .uebb95ef1a784721e03cd07ea72909441:active , .uebb95ef1a784721e03cd07ea72909441:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uebb95ef1a784721e03cd07ea72909441 .centered-text-area { width: 100%; position: relative ; } .uebb95ef1a784721e03cd07ea72909441 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uebb95ef1a784721e03cd07ea72909441 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uebb95ef1a784721e03cd07ea72909441 .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; } .uebb95ef1a784721e03cd07ea72909441:hover .ctaButton { background-color: #34495E!important; } .uebb95ef1a784721e03cd07ea72909441 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uebb95ef1a784721e03cd07ea72909441 .uebb95ef1a784721e03cd07ea72909441-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uebb95ef1a784721e03cd07ea72909441:after { content: ""; display: block; clear: both; } READ: Virtual Banking EssayThe final discussion between Sam and Hally about theirexperiences during the day and the dance championship that Samand Willie are going to participate in demonstrates the politicaltensions in the world during Fugards lifetime. Sam points outto Hally that people are bumping into each other all the time(1317) and nobody knows the steps and theres no music playing(1317). Sam said, Ive bumped into Willie, the two of us havebumped into you, youve bumped into your mother, she bumping intoyour Dad_(1317). Sam is using their experiences that day torepresent how countries are in constant conflict. He points outto Hally that America has bumped into Russia, Engl and is bumpinginto India, rich man bumps into poor man (1317). Sam says thatat the dance, theyre going to see six couples get it right, theway we want life to be (1317-1318). Sam uses the dance torepresent the hope that was held by people in Fugards lifetimeabout the political future of the world by looking at these sixcouples success. He convinces Hally that the world does havehope for political stability because Hally states that maybethere is some hope for mankind after all (1318). Sam uses allof these examples about their experiences during the day and thedance championship to demonstrate the political tensions thatwere present in Fugards lifetime. Although the discussions between Sam and Hally seem to beconfined to the characters lives, the discussions are much morecomplex than they appear. These three discussions between Samand Hally demonstrate the religious, racial, and politicaltensions that Athol Fugard grew up facing in South Africa. Thediscussion about who is a man of magnitude (1300) demonstratesthe religious tensions. The second discussion that occurs afterHally learns that his father is coming home demonstrates theracial tensions. Finally, the third discussion about Sam andHallys experiences during the day and the dance championshipdemonstrates the political tensions of Fugards lifetime in SouthAfrica.
