Colored Fire Spray Bottles

In the pilot episode of Breaking Bad, chemistry teacher Walt White performs a demonstration in which he changes the color of a bunsen burner flame by spraying the flame with chemicals. You can perform the colored fire demonstration yourself. All you need are some common chemicals, alcohol, and spray bottles. Here is a list of metal salts you can use to (safely) color fire. The chemicals have low toxicity and any smoke produced wont be any better/worse for you than normal wood smoke: Colored Fire Chemicals Heres a list of common chemicals and the colors of flames they produce: Dark red lithium chlorideRed strontium chloride (found in emergency flares)Orange calcium chloride (a bleaching powder)Yellow sodium chloride (table salt) or sodium carbonateYellowish green borax (sodium borate, a common insecticide and cleaning agent)Green copper sulfate (found in some pool and aquarium chemicals)Blue copper chloride (lab chemical, but other copper compounds found in algicides and fungicides may work)Violet 3 parts potassium sulfate, 1 part potassium nitrate (saltpeter)Purple potassium chloride (sometimes sold as a salt substitute)White magnesium sulfate (Epsom salts) Prepare the Flame Colorants If you were just coloring a campfire or other wood fire, you could simply sprinkle the dry metal salts onto the fire. Copper chloride is especially nice for this since the sodium that is naturally present in wood causes this chemical to produce a mix of blue, green, and yellow flames. However, for the gas flame in a burner, you need the salts dissolved in a flammable liquid. The obvious choice here is alcohol. Common alcohols found around the home could include rubbing alcohol (isopropyl alcohol) or ethanol (e.g., in vodka). In some cases, the metal salts will first need to be dissolved in a small volume of water and then mixed with alcohol so that they can be spray onto a flame. Some salts may not dissolve, so what you can do is grind them into a fine powder and suspend them in liquid. Do not spray alcohol or any flammable chemical across a flame toward people! Safety Information While the colorants used in this demonstration are generally safe, this project involves flammable materials and flames. There is an innate risk of burns and uncontrolled fire. Be sure to have a working fire extinguisher handy, wear appropriate safety gear, and maintain a safe distance between the demonstration and the demonstrator/audience. Flames involving alcohol may be extinguished with water, by suffocation, or with any fire extinguisher. The demonstrator is advised to wear low-flammability clothing (typically natural fibers) rather than flammable synthetic clothing. A little preparation makes for a safe and memorable demonstration that will raise interest in chemistry!

Global Status Report on Alcohol †Free Samples to Students

Question: Discuss about the Global Status Report on Alcohol. Answer: Introduction Alcoholic beverages are one of the most widely consumed drinks in Zurich. The alcoholic beverages include a wide variety of drinks, each with its own innovation, taste and grace. This assignment highlights the business plan of a bar at Zurich. A detailed business plan is given along with the details of the staffing strategies. The beverages that will be presented in the bar and its preparations are also highlighted. The business plan includes the location at which the bar would be set up. The location is chosen in such a way that the regular office goers might enjoy a drink after their hectic day. Thus, the location of the bar needs to be strategically placed at the business hub of Zurich (Cain 2014). The bar needs to incorporate various strategies such as giving high discounts to the regular customers, such that they are able to attract more customers and retain the customers. Details of the bar and staffing strategies The bar has to be decorated such that the visitors get a good ambiance and enjoy themselves. Moreover, it is essential to give the visitors a good and relaxing experience (Sabia et al. 2014). The staffs need to be selected in such a way that they are able to cater to the needs of the visitors. The staff selection has be done after taking rigorous rounds of interview of the people, such that the most suitable employee with the most desirable skill could be selected. Martini Margarita Sour Mojito Pina colada Highball Sangria Manhattan Gin and Tonic Bloody Mary Daiquiri White Russian Wine Cocktail Cosmopolitan Long Island Iced tea Hurricane Tequila Sunrise Rum Champagne Whiskey Beer Vodka Preparation of the beverages In order to prepare the above mentioned beverages, various kinds of alcohol are needed, along with fruit juices in order to prepare cocktails (Howland and Rohsenow 2013). Skilled chefs are needed to prepare the beverage delicacies, as they need to know, which liquor mixed in what proportion, with which alcohol, would give a soothing and pleasant sensation to the customers (World Health Organization, 2014). Boston Shaker: This refers to a shaker that is needed to ix two or more drinks and mixes them well. Hawthorne Strainer: This is used to strain a drink. Bar spoon: This is a special kind of a spoon for stirring drinks and scooping out fruits or ice creams. This is essential equipment for the bar. Muddler: This is used to extract the flavours of the fruits and herbs in the drinks. Citrus Zester: This is used to extract the zest of the citrus fruits such as lemons and melons and serve with the drinks (Kponee, Siegel and Jernigan 2014). Fruit press: This is the most hygienic way of extracting fruit juices to be served with the drinks. Bottle opener: This is inevitable equipment, without which the bar cannot operate. Since the bar will be opened at a business hub of Zurich, hence the possible expected customers are the people returning from office. The customers also include the clients who have been visiting the place. The business executives are the loyal clients of the bar, who visit the bar every day. The costs of the items are reasonable and according to the contemporary bars in the vicinity. The drinks range from 3 Francs to 30 Francs. Food and snacks menu The food and snack items that are served with the bar are as follows: Nuts Spiced nuts Chicken starters Pork Starters Bread Fish and Chips The hours of operation are 6pm to 4am. This is because, most of the people visits the bar at these hours. Hence the hours of operations are chosen such that the maximum number of people visits the bar (Orlowski, Murphy and Severt 2016). The hours of operation is assigned in order to get the maximum number of customers in the minimum operational hour. Conclusion The bar and its detailed menu have been presented in this assignment. The business plans, along with the staffing requirements have been presented. The list of beverages to be served and the food to be served with the beverages is also mentioned in this assignment.

Today It Has Become A Truism To Say That The Mediu Essay Example For Students

Today It Has Become A Truism To Say That The Mediu Essay m Of Photography Is Light. ButToday it has become a truism to say that the medium of photography is light. But the skill required to capture that light in ways that celebrates its beauty and mystery has been mastered as fully by Ansel Adams as by almost any other twentieth-century photographer. And it seems highly appropriate that the name of the exhibition contains the words FIAT LUX: let there be light,As a case in point we may contemplate the beautiful fragment of Bristlecone Pine Wood at the White Mountain High Altitude Station. Here the stark light-dark-light contrasts reveal Adams at his best. While the sunsets light accentuates the shapes of the wood at its edges, so that it glows with luminescence, the darker tonalities remind us that this fragment is as much dead as it is alive, and thus reminds us of our own mortality. We will write a custom essay on Today It Has Become A Truism To Say That The Mediu specifically for you for only $16.38 $13.9/page Order now For me this image also suggests that we pay greater attention to the cultivation and preservation of nature, its delicate balances, which, when neglected, lead to devastation, as is occurring in the rain forests of Brazil. Even in juxtaposition with death, however, this lovely Adams image speaks of the glory of life. I dont know of a more spectacular view than the one from the top of the Berkeley hills across the San Francisco Bay toward the city, and the Golden Gate Bridge in the distance. The silent serenity of this photograph contrasts markedly with the devastation of recent events. As beautiful as this image is we also know that many areas of the greater area of the San Francisco Bay are polluted. In a photograph taken from the Lick Observatory the scientific facility is not visible, but we still, with the knowledge of the vantage point from which it was taken, sense the precarious balances of nature and technology, which so universally threaten the existence of both, including threats to outer space, reminding us to heed the ever-increasing warnings of pollution. The misty delicacy which characterizes this photograph of rolling hills, outlined with light, and trees, which are threatened by drought, makes us wonder how long these species will remain. Whether young or old, located in a city, or in more remote environs, whether researching the fruits of the earth or the mysteries of outer space, these never-before-exhibited images provide a wealth of visual information about the varieties and richnesses of our world.
