Purple Fire - Easy Instructions for Colored Flames

Purple Fire - Easy Instructions for Colored Flames You can make purple fire yourself using common ingredients. Keep in mind purple is a tricky fire color to produce because there is no wavelength of light that is responsible for a color between red and violet, yet fire colors mostly are produced by the emission spectra of chemicals. In order to get purple, you need to produce violet flame and red flame. Purple Fire Ingredients You can burn the salts that produce the colors in any fire, but youll get the best results if you use a blue flame, like the type produced by lighter fluid or alcohol. Lighter fluid, alcohol or alcohol-based hand sanitizerLite salt (potassium chloride)Red emergency flare (contains strontium nitrate) Get Strontium From the Flare The emergency flare is a long cardboard tube with a striker at one end. Leave the striker end alone and use your fingers to peel away the bottom of the cardboard to reveal the powdery substance inside the flare. Collect this material in a bowl or plastic baggie. You only need a little, so store the rest for later. You can throw away the cardboard and striker (or save them for another project). Making the Purple Fire All you need to do is sprinkle some of the contents of the flare and some lite salt onto a fireproof surface, add the fuel and ignite the mixture. The proportions of the chemicals are a matter of personal preference. Add more lite salt if you want a more violet flame. If you want a reddish or pink flame, use a larger amount of flare content. Tips and Cautions Its fire, so treat it with respect. Further, be advised the flare contents will burn very brightly if you light them on their own. The best fuel for this project is diluted alcohol where water can moderate the rate of combustion. The flame in the picture uses an ethanol-based hand sanitizer. The project also works well with Ronsonol lighter fluid or with rubbing alcohol. However, lighting the mixture without the liquid fuel will give you just a bright red flame from the flare.

Advantages And Disadvantages Of In Depth Interviews Psychology Essay

Advantages And Disadvantages Of In Depth Interviews Psychology Essay Health, social work, education and other social activities are considered as social sciences and fields of practice because they influence peoples lives every day (Merriam 2009).

Subcontracting strategy for future SBM offshore projects and its Dissertation

Subcontracting strategy for future SBM offshore projects and its implemetntation - Dissertation Example Subcontractors have increasingly become important players in enhancing the productivity and economic strategies of a company. However, not much empirical studies have been done on these issues. The main purpose of this study is to investigate the process of subcontracting and find options for optimizing the value chain in the oil & gas industry by reviewing and analyzing previously written literature on the chosen topic for the research. In the literature review section, the concepts of subcontracting, risk management, contracts, project management, supply chain management, value chain and transaction cost theory are discussed. A single case study was applied in this thesis. The company chosen for the case study is SBM Offshore and is located in Netherlands. To carry out the research, a qualitative research approach was implemented. Primary data was collected through semi structured interviews. In addition to this, secondary data from different sources such as articles, journals, boo ks and company resources were used to construct or build the theoretical frame of reference for the thesis. The subcontracting philosophy should stipulate that the scope of the work to be subcontracted will be determined by risk assessment and performance of subcontracting companies. Also, contract requirements will meet regulatory compliance of safety and performance along with meeting the company’s standards.

Plato's advise to President-Elect Obama Essay Example | Topics and Well Written Essays - 500 words

Plato's advise to President-Elect Obama - Essay Example A difficult, if not impossible, task awaits you to start clean when you take office. So much has gone wrong, and the consequences of previous rulers’ actions will follow you throughout your time in office. But take my advice, the genuine ruler â€Å"will take society and human character as his canvas, and begin by scraping it clean. . . . [H]e will not consent to take in hand either an individual or a state or to draft laws, until he is given a clean surface to work on or has cleansed it himself† (p. 209). You can’t hope to fix anything if failed policies and actions can’t be scraped away to make room for better governing. Weigh carefully in your mind, when you’re asked to make decisions, the worth of a specific action, over and above what it means to those who petition you. Don’t be afraid to end policies that weren’t set up with the people’s best interest in mind in the first place. Keep the greater good of the whole populatio n in mind, rather than the complaining voices of lobbyists and congressmen. Philosophically weigh the consequences of the war and the nation’s economic policies, and make decisions from a clean slate if those previous policies aren’t working. The man who held office before you seemed to me drunk with power. I believe â€Å"access to power must be confined to men who are not in love with it† (p. 235). If you fall in love with being leader of what’s been called the greatest nation on earth, you’ll forget why you were elected to this office in the first place: to serve the people. Make your life good and wise first, and then you’ll be happy and be able to rule the nation philosophically and not through power. â€Å"All goes wrong when, starved for lack of anything good in their own lives, men turn to public affairs hoping to snatch from thence the happiness they hunger for† (p. 235). Men and women who rule the nation must be philosophers

The Clash of Civilizations Essay -- Analysis, Samuel P. Huntington

Ernest Hemingway stated that, â€Å"In modern war †¦ you will die like a dog for no good reason†! Even though that is true, experts have gone further by trying to find the â€Å"roots† and explain why conflicts emerge in the first place. Two experts, Samuel P. Huntington and John R. Bowen, present two different approaches towards the cause of conflicts in 21st century. Although there is a difference between their approaches, both of them share the common believe that a conflict may occur when one puts pressure on the other; but the reason why this pressure takes place, varies among the two theories. In his article, â€Å"The Clash of Civilizations†, Huntington points out that in the 21st century, conflicts will not occur based on ideology of a state or civilization, neither on economic power; but they will take place because the differences in cultural and religious identity between civilizations. As the first key point that lies under this theory, is the Western civilization approach towards the Eastern civilization. According to him, the Western Civilization promotes their â€Å"political and economic values, maintain their predominance and protect their interest† through economic and political pressure via Western Institution such as UN and IMF. This Western approach increases the cultural division between Western and Eastern civilization, but also within Western Civilization; between Western Christianity and Orthodox Christianity. This approach can be easily understandable if we take a look at the historical events where Western and Eastern civilization confron ted each other such as in the Gulf War and Bosnian war, where Western used their power to protect countries from a same culture, same civilization. This leads to a reaction from Eastern cou... ...up and swap a part of the region, thus creating Western vs. Eastern conflicts which apparently will lead to war between two complete different ideologies. To conclude, wars have been and will be part of our lives. In some regions, people yet have lack of knowledge, therefore tend to separate people based on language, culture, religion, region and historical background. Yet we didn’t manage to overpass these obstacles that we create towards the minorities, and live in the same land together. Although some countries try to get rid of those issues and live beyond ethnicity borders, there are countries that point the figure at you and remind you that you are â€Å"you†, and because you are who you are â€Å"We hate you†! When we overpass the hate, the ethnic borders, there won’t be any conflicts, wars and articles that are trying to find the way how the conflict occurred!
