Exploding Mentos Drink Experiment

A friend sent me a link to a Wired how-to project called The Manhattan Project in which you freeze a Mentos candy into an ice cube and place it in a carbonated drink. When the ice cube melts, the wax surrounding the candy will be exposed and the drink should erupt. Does it work? Lets find out. Exploding Mentos Drink Ingredients The drink in the original recipe called for whiskey, sweet vermouth, and bitters (basically a Manhattan plus diet cola), but you can make a rum and coke or whatever you like or just try the non-alcoholic version using two ingredients: Diet colaMentosâ„ ¢ candy Make the Exploding Drink Ill tell you right up front: a drink with soda and Mentos wont explode unless it is in an enclosed container. Exploding drinks make messes, plus they tend to spray out shards of glass, so its a good thing this drink isnt so violent. Erupting is more what youre looking for here. If you want to cause an unexpected eruption, freeze a single Mentos candy into the well of an ice cube tray. Youll get the best results if you wait until the ice is almost frozen and then add a Mentos candy to each cube so that its near the surface of the ice. You dont want to soak the candy in cold water or its coating will dissolve. If that happens, all youll get when you mix it with diet cola is candy-flavored cola. The premise is that the Mentos will become exposed as the ice cube melts. When the wax coating of the candy reacts with the diet soda, the drink will fizz and bubble like the classic Mentos and diet soda fountain. If youre doing the project on-purpose or else dont mind getting caught dropping a Mentos into someones carbonated drink, you can simply plop the candy in the soda -- no ice cube needed. How the Mentos in Ice Cubes Trick Works Among other things, the gum arabic that coats a Mentos candy lowers the surface tension of the soda, allowing carbon dioxide bubbles to rise and expand more easily. The candy coating traps the gas, forming bubbles and foam. When I tried this project, I didnt get a spectacular eruption, but you can expect somewhat better results if you use a narrow glass for your drink. Except that the Mentos flavors the drink, I dont think someone with a Mentos-laced ice cube would notice much happening or suffer from an out-of-control foaming drink. The project is still pretty fun.

Mexican Immigrants And The Mexican Community - 915 Words

When we think of the word â€Å"criminals,† we automatically think thieves, murderers, or rapists. Not Donald Trump. He launched his presidential campaign with words of loathe towards undocumented immigrants, especially towards the Mexican community. â€Å"When Mexico sends its people, they’re not sending their best.† Trump declared, â€Å"They’re sending people that have lots of problems and they’re bringing those problems with them. They’re bringing drugs, they’re bringing crime. They’re rapists, and some I assume, are good people.† Trumps words were fast to circulate around social media. Many people were quick to make fun of him. According to ABC news, many important companies such such as Univison, Televisa, NBC, and Macy’s were quick to terminate their contracts with him. â€Å"Mr. Trump hasn’t demonstrated understanding or respect toward Mexican migrants and has offended the entire Mexican population. † Televisa said after firing Trump.

Running Head: GVT Task 2 GVT Task 2 Maureen O’Connor Western Governors University The mouth, pharynx, esophagus, stomach, small intestine consisting of the duodenum, jejunum, ileum, and large intestine consisting of the transverse colon, descending colon, ascending colon, cecum, sigmoid colon, rectum, vermiform appendix and anus are all part of the alimentary canal. The function of the alimentary canal is to provide nourishment. The teeth, tongue, gallbladder, salivary glands, liver and pancreas are considered to be accessory digestive organs. We will write a custom essay sample on Gvt Task 2 or any similar topic only for you Order Now These organs produce saliva (salivary glands), bile (gallbladder and liver) and digestive enzymes which contribute to the breakdown process of food. Mechanical digestion begins with the process of taking food into the mouth or ingestion and chewing it until it can be moved through the alimentary canal during the propulsion process. This process includes swallowing and in a series of muscle contractions and relaxation it is then moved from one organ to another. Swallowing is performed in the pharynx while peristalsis occurs in the esophagus, stomach, small and large intestine. Breakdown of the food in the stomach, also called churning and in the small intestine are also part of the mechanical digestion process. When food leaves the stomach the process of chemical digestion begins. This is when carbohydrates, proteins, and lipids are broken down into simple sugars, amino acids, fatty acids and glycerol, otherwise known as chemical building blocks. Enzymes are chiefly responsible for carrying out chemical digestion and are secreted in the central cavity of the alimentary canal. Digestive enzymes include salivary and pancreatic amylase, present in the mouth and small intestine, maltase and lactase which are also present in the small intestine and are involved with carbohydrate digestion. Pepsin which is present in the stomach and chymotrypsin present in the small intestine both involved with protein digestion. Aminopeptidase breaks down amino acids during protein digestion. Finally pancreatic lipase is involved with fat digestion. Summary of Two Experiments An experiment performed in the Department of Food Sciences and Nutritional Health at Kyoto Prefectual University involved polylysine which had been used as a food additive in Japan for many years. The researchers were interested in how polylysine inhibited pancreatic lipase. They performed the experiment on rats and then measured the effect of the polylysine after the rats were fed a meal. These measurements were taken after the rats had been administered fat emulsion with the polylysine and fat emulsion without polylysine. The results suggested that polylysine had the ability to inihibit pancreatic lipase in the small intestine and suppressed dietary fat absorption. A second experiment involved alpha-amylase inhibition from the white kidney bean and its effect on weight loss and blood glucose levels. Clinical studies in which subjects were given the white bean product and their after meal glucose levels were studied. A group of subjects with diabetes were also given the white bean product and there was found to be a decrease in their after meal glucose levels. There were more clinical studies in which subjects were given varying doses of the white bean product along with amino acids with varying levels of dietary intake. The conclusion was that alpha-amylase inhibitor does have an effect on the absorption rate of carbohydrates and be a factor in weight management as well as type 2 diabetes mellitus control.

If I add lipase and hydrochloric acid to peanut butter this should cause a change in the consistency of the peanut butter after 1 hour. The lining of the stomach secretes gastric juices including hydrochloric acid which dissolves food, pepsin which is a protein-splitting enzyme and lipase, a fat-dissolving enzyme. By adding the Biuret solution to identify the presence of protein to each cup containing peanut butter, enzymes and hydrochloric acid there should be a change in color to pink or purple.

The absorption of protein then occurs and amino acids enter capillary blood via villi and subsequently transported via the hepatic portal vein to the liver. Although lipase is present in the stomach it is not very effective because the stomach is a strongly acid environment. The majority of fat digestion happens in the small intestine although it needs bile from the liver to break it down into glycerol and fatty acids. Once that occurs the fatty acids enter the lacteals of the villi for transportation via lymphatic transportation to the thoracic duct. Glycerol and fatty acids (small-chain) are transported via the hepatic portal vein to the liver. How to cite Gvt Task 2, Papers

The Spanish Tragedy †A monologue from the play by Thomas Kyd Analysis Essay Example For Students

The Spanish Tragedy – A monologue from the play by Thomas Kyd Analysis Essay A monologue from the play by Thomas Kyd NOTE: This monologue is reprinted from The Spanish Tragedy. Thomas Kyd. London: J. M. Dent Co., 1898. GHOST: When this eternal substance of my soul Did live imprisond in my wanton flesh: Each in their function serving others need, I was a courtier in the Spanish Court. My name was Don Andrea, my descent Though not ignoble, yet inferior far To gracious fortunes of my tender youth: For there in prime and pride of all my years, By Duteous service and deserving love, In secret I possessd a worthy dame, Which hight sweet Bel-imperia by name. But in the harvest of my summer joys, Deaths winter nippd the blossoms of my bliss, Forcing divorce betwixt my love and me. For in the late conflict with Portingale, My valour drew me into dangers mouth, Till life to death made passage through my wounds. When I was slain, my soul descended straight, To pass the flowing stream of Acheron: But churlish Charon, only boatman there, Said that my rites of burial not performd, I might not sit amongst his passengers. Ere Sol had slept three nights in Thetis lap And slakd his smoking chariot in her flood: By Don Horatio our Knight Marshals son, My funerals and obsequies were done. Then was the ferryman of hell content To pass me over to the slimy strond, That leads to fell Avernus ugly waves: There pleasing Cerberus with honeyd speech, I passd the perils of the foremost porch. Not far from hence amidst ten thousand souls, Sat Minos, Aeacus, and Rhadamanth, To whom no sooner gan I make approach, To crave a passport for my wandring ghost: But Minos in graven leaves of lottery, Drew forth the manner of my life and death. This knight (quoth he) both livd and died in love, And for his love tried fortune of the wars, And by wars fortune lost both love and life. Why then, said Aeacus, convey him hence, To walk with lovers in our fields of love: And spend the course of everlasting time, Under green myrtle trees and cypress shades. No, no, said Rhadamanth, It were not well, With loving souls to place a martialist: He died in war, and must to martial fields: Where wounded Hector lives in lasting pain, And Achilles myrmidons do scour the plain. Then Minos mildest censor of the three, Made this device to end the difference. Send him (quoth he) to our infernal King: To doom him as best seems his majesty. To this effect my passport straight was drawn. In keeping on my way to Plutos court, Through dreadful shades of ever-glooming night, I saw more sights than thousand tongues can tell, Or pens can write, or mortal hearts can think. Three ways there were, that on the right hand side Was ready way unto the foresaid fields, Where lovers live, and bloody martialists, But either sort containd within his bounds. The left hand path declining fearfully, Was ready downfall to the deepest hell, Where bloody furies shake their whips of steel, And poor Ixion turns an endless wheel. Where userers are chokd with melting gold, And wantons are embracd with ugly snakes: And murderers groan with never killing wounds, And perjurd wights scalded in boiling lead, And all foul sins with torments overwhelmd. Twixt these two ways, I trod the middle path, Which brought me to the fair Elysian green. In midst whereof there stands a stately tower, The walls of brass, the gates of adamant. Here finding Pluto with his Proserpine, I showd my passport humbled on my knee. Whereat fair Proserpine began to smile, And beggd that only she might give my doom. Pluto was pleasd, and seald it with a kiss. Forthwith (Revenge) she rounded thee in th ear, And bad thee lead me through the Gates of Horn, Where dreams have passage in the silent night. No sooner had she spoke but we were here, I wot not how, in twinkling of an eye. .u4e30026a9d18c766c0b11a0f7ac90ee6 , .u4e30026a9d18c766c0b11a0f7ac90ee6 .postImageUrl , .u4e30026a9d18c766c0b11a0f7ac90ee6 .centered-text-area { min-height: 80px; position: relative; } .u4e30026a9d18c766c0b11a0f7ac90ee6 , .u4e30026a9d18c766c0b11a0f7ac90ee6:hover , .u4e30026a9d18c766c0b11a0f7ac90ee6:visited , .u4e30026a9d18c766c0b11a0f7ac90ee6:active { border:0!important; } .u4e30026a9d18c766c0b11a0f7ac90ee6 .clearfix:after { content: ""; display: table; clear: both; } .u4e30026a9d18c766c0b11a0f7ac90ee6 { 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; } .u4e30026a9d18c766c0b11a0f7ac90ee6:active , .u4e30026a9d18c766c0b11a0f7ac90ee6:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u4e30026a9d18c766c0b11a0f7ac90ee6 .centered-text-area { width: 100%; position: relative ; } .u4e30026a9d18c766c0b11a0f7ac90ee6 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u4e30026a9d18c766c0b11a0f7ac90ee6 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u4e30026a9d18c766c0b11a0f7ac90ee6 .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; } .u4e30026a9d18c766c0b11a0f7ac90ee6:hover .ctaButton { background-color: #34495E!important; } .u4e30026a9d18c766c0b11a0f7ac90ee6 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u4e30026a9d18c766c0b11a0f7ac90ee6 .u4e30026a9d18c766c0b11a0f7ac90ee6-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u4e30026a9d18c766c0b11a0f7ac90ee6:after { content: ""; display: block; clear: both; } READ: The seven against thebes Essay
