How to Make Black Snake or Glow Worm Fireworks

How to Make Black Snake or Glow Worm Fireworks Black snakes, sometimes called glow worms, are small tablets that you light, using a punk or a lighter, that burn to produce long black snakes of ash. They produce some smoke (which had a characteristic, probably toxic odor), but no fire or explosion. The original fireworks used to contain salts of a heavy metal (such as mercury), so while they were marketed for kids to play with, they really werent that much safer than conventional fireworks, just dangerous in a different way. However, there is a safe way to make black snakes. You can heat baking soda (sodium bicarbonate) with sugar (sucrose) to produce carbon dioxide gas that puffs up black carbon ash (see a video). Black Snake Materials SandAlcohol or fuel oil (High-proof alcohol or lighter fluid works well for this  project)Baking sodaSugar (Powdered sugar or you can grind table sugar in a coffee grinder) Steps to Make Snakes Mix 4 parts powdered sugar with 1 part baking soda. (Try  4 teaspoons sugar and 1 teaspoon baking soda)Make a mound with the sand. Push a depression into the middle of the sand.Pour the alcohol or other fuel into the sand to wet it.Pour the sugar and soda mixture into the depression.Ignite the mound, using a lighter or match. At first, youll get a flame and some small scattered blackened balls. Once the reaction gets going, the carbon dioxide will puff up the carbonate into the continuously extruded snake. You can also make black snakes without sand mix baking soda and sugar in a metal mixing bowl, add the fuel and light the mixture. It should work fine. These will have a distinct, familiar smell... of burnt marshmallows. Finally, rest assured that if you use pure ethanol, sugar, and baking soda, there is nothing toxic about this project. One caution: Dont add fuel to the burning snake, since you risk igniting the alcohol stream. How Black Snakes Work The sugar and baking soda snake proceeds according to the following chemical reactions, where sodium bicarbonate breaks down into sodium carbonate, water vapor, and carbon dioxide gas while burning the sugar in oxygen produces water vapor and carbon dioxide gas. The snake is carbonate with black carbon particles: 2 NaHCO3 → Na2CO3 H2O CO2 C2H5OH 3 O2 → 2 CO2 3 H2O These instructions were adapted from a tutorial given on Boing Boing which in turn came from a defunct Russian site. The Russian site suggested two additional ways to make chemical snakes: Ammonium Nitrate Black Snake This works the same way as the sugar and baking soda snake, except using ammonium nitrate (niter) instead of sugar. Mix one part ammonium nitrate and one part baking soda. This recipe is more like what you would see in commercial black snake fireworks, which are supposedly composed of soda with nitrated naphthalenes and linseed oil. Its another very safe demonstration, though not safe enough to eat, like sugar and baking soda. Ammonium Dichromate Green Snake The green snake is a variation on the ammonium dichromate volcano. The volcano is a cool chemistry demonstration (orange sparks, green ash, smoke), but its a chemistry-lab-only demonstration (not safe for kids at all) because the chromium compound is toxic. The green soda snakes are made from: Two parts of ammonium nitrateOne part of powdered sugarOne part of ammonium dichromate Mix the ingredients, add a small amount of water, and roll the result into a snake shape (using gloves is strongly recommended). Allow the snake to dry (the tutorial suggests using a hairdryer to speed the process). Light one end of the snake.  Its worth knowing how to do this demonstration if you have ammonium dichromate and ammonium nitrate on hand, otherwise, let the Russian photos suffice and play with the sugar and baking soda snakes instead.  In this case, an orange snake burns to green ash.  Another (spectacular) form of black carbon snake results from reacting sugar and sulfuric acid.

Language and Culture in New Zealand Organization Research Paper

Language and Culture in New Zealand Organization - Research Paper Example According to the research findings, it can, therefore, be said that various languages are spoken in the country where some are officially recognized, and others are not. These diverse languages bring about different cultures and influence the organization structure of the country. New Zealand is located in the Southwest of the Pacific Ocean. The country is mainly made up of two landmasses namely the South and North Islands. Several ethnic groups can be found in New Zealand, which includes the Maori, Europeans, Asians, and Pacific Islander among others. The country's official languages are Maori, English and the New Zealand sign language. English can be termed as the main business language, as it is spoken by 98 % of the citizens this can be attributed to the British Commonwealth ties. Maori is considered a Polynesian language which can be compared to languages spoken in other Pacific Cultures such as Tongan, Samoan and Hawaiian. As per the census done in 2006, more than 157,000 peopl e in the country speak Maori. This language has existed in New Zealand culture from as early as the country’s discovery. Maori people were the first to get to New Zealand and were later followed by the European settlers. However, it was only after passing of the 1986 Maori Language Act that the language was formally recognized as an official language. The use and the development of Maori language is consistently encouraged by the New Zealand language Commission. English and Maori are used all over the country in varied media outlets especially in radio and television programs. As apparent in most regions of the world where cultures have intermixed, Both English and Maori cultures have influenced each other. Various words have been absorbed into the vocabulary of the two languages. There are quite a number of differences in the above cultures especially when tribal circles are involved.

IT104 Essay Example | Topics and Well Written Essays - 4500 words

IT104 - Essay Example Without successful prioritization of tasks and responsibilities, online courses might turn-out to be a bad experience. Technology makes online classes possible, but they can also be a barrier to success in the online learning environment. One possible technological problem is having a computer that is not capable of delivering the content that the professors have developed for the course. Your computer may be incapable of streaming video, for example, because it is outdated or damaged. If the professor has lots of videos as a part of the coursework, then you will be out of luck due to a slow computer or internet connection. A final barrier to on-line learning is the problem of having a single computer to service multiple learners in the household. This is not an insurmountable obstacle, but it does require a fair amount of foresight and scheduling. Running out to buy additional computers is not in most people’s budgets. By creating a schedule of computer use, just as in a libr ary, everyone can use the computer to get what they need. Exercise 2 I expect this course to give me the skills and information needed for me to improve my teaching. I am currently teaching Aesthetics and have a strong desire to be the best educator possible. I know my subject matter very well, but am concerned that I might not always be using the best teaching techniques. I hope that through the course of this study, I will be able to learn better presentation skills and gain a better understanding of how adults learn best. I realize that teaching children and teaching adults is a very different process. What works for one does not always work for the other. As a result, I am often wondering if the lessons and assignments I am developing are more appropriate for younger learners than the age of student I have. I often have a nagging feeling that there is just more information and knowledge out there that would help me be such a better teacher. The problem is, I only am able to crea te lessons based on my existing teaching experience. I expect this course to broaden my educational understanding so that I will have more confidence in the lessons and assignments I develop. It is my hope that this course will inspire me to alter some of the less effective lessons I currently have developed and to develop new lessons based on my new understanding of how adult learners learn best. In essence, I expect this course to give me the additional skills and information necessary for me to be a more effective and interesting teacher of Aesthetics. My ultimate goal is to have my adult learners transfer their knowledge into their everyday lives. This is true for me in regards to this course as well. Exercise 3 This planner can be a very helpful tool because it helps the adult student returning to the classroom to organize their dreams into concrete plans. It also is very good at helping the student to imagine the far reaching effects of returning to school, gaining an educatio n and possibly changing jobs. Some of the affects might not be as positive as they imagine and I think it is important for adult learners to re-enter school with their eyes wide open. Most adult learners focus on the additional time schooling will take and the economic rewards they will realize with improved education. Rarely do they consider the profound changes

Vagueness, Ambiguity, and Clarity in Writing Essay Example for Free

Vagueness, Ambiguity, and Clarity in Writing Essay Example 2: I was thrown from my truck as it left the road. I was later found in a ditch by a flock of wild turkeys. The vagueness about this sentence is it is not clear as to who was thrown from the truck you do not know what the writer meant. The second portion of the sentence is unclear on whether the wild turkeys are in the ditch the person is lying in or were they alongside the ditch the person was lying in. Example 3: Next Sunday a collection will be taken to help with the cost of the new altar. Anyone wanting to help to do something on the new altar can step forward and let the committee know. It is unclear actually what is being collected is it a collection of money or names in a basket to be called upon. Asking if anyone wants to do something to help on the new altar. The writer does not make it clear just what is being asked of what the â€Å"something† is on the new altar. These sentences are vague and ambiguous because it leaves too many ways that you could interpret the writers’ intent. Both vagueness and ambiguity is influenced in the understanding of these sentences because anyone could misunderstand what the writer is saying. As a writer, you must make very sure you get your ideas across clearly. The relationship between critical thinking and clear writing is that you first need to know actually what you want to say before you write it. Also you need to make sure that the research and information is accurate.

Leadership Essay -- Trait Theory, Maslow

Leaders impact people's daily lives and futures. In good times and bad, there is always a need for strong leadership. According to Fesler (1960) leadership is a social process, it cannot exist without leader and followers. Leadership is results in followers’ behavior that is goal-directed in some sort of organized setting. In brief, leadership is a process by a person influences others toward the attainment of group or organizational goals. Like the words said by Keith (2003):† Leadership is ultimately about creating a way for people to contribute to making something extraordinary happen†. The development of leadership studies has three phases: trait theory, behavior theory and contingency theory. According to Robbins& Judge (2011), the studies at late of 1960s are applied to the â€Å"great man† theory which state that the leads are born to lead, they are not like other people and they have some special trait. The researchers examined the physical, mental, and social characteristics of individuals, they are expected to find out what kinds of trait will means the people is the leader. However, Fry& Kriger (2009) indicated that leader trait research ignored followers’ needs and not gives explanations for the proposed relationship between individual characteristics and leadership; it is not consider the impact of situational factors that might moderate the relationship between leader traits and measures of leader effectiveness. As a result of these drawbacks, trait theory is not successful and generally abandoned. While aware of the limitations of trait theory, the focus of leadership research shifted away to leader behaviors. The researchers begin to observe the relationship between behavior and leader effectiveness. The behavior ... ... the leader behavior that will accomplish these tasks depends upon the subordinate and environmental contingency factors. In conclude, there is no best way or universal style to manage an organization. A good must think over the situation around and find out an appropriate leadership style. Although Anna Bligh’s behavior is not totally same with effectiveness style which is indicated by behavior leadership studies, but her style is appropriate to the situation she met, and consistent with the definition of effectiveness leadership under contingency theory. Her case is also proof that behavior leadership has offered many kinds of leader style but a good leader generally should not use the same style with a group in different situation. Like contingency theory indicated: most efficacious leadership is the style that accordance with current circumstance.

Segmentation of Music Industry

Music industry Segmentaion When attempting to segment a particular consumer base or population by personality or motivation, one must consider what personality traits the consumers posses. Of course there are serveral ways to group together personalities ex (fashionable, innovative, extroverted, etc). I have chosen to use Karen Horney’s theory of three personality groups for segmentation of the music consumer market. Karen Horney states that people can be grouped into three personalities; compliance, aggression and withdrawl.Since music consumers can be an almost entire population, it would be a good idea to segment this population into three broad groups. The first personality group, compliance, is can be defined as people who move toward others. This group has a need for affection and approval and a need to be liked by others. The complaint personality consumer would tend to veer toward popular current music or popular music within a certain genre. This is the consumer who w ould be listening to Justin Timberlake and Lady GaGa when they are at their peak.They would be drawn toward the â€Å"summer hits†, toward the songs that are played at clubs and they dance to with their friends. In terms of music consumers, they might be seen as between the ages of 10-40, and this is a very big market withing the music consumer industry. The second personality group, aggression, are considered those who go ahaist toher. This group has a need for power and for control over others. They have the need to be heard by others and fear of seeming stupid. This personality group would be the ones who view themselves as against the popular music, against very popular groups and singers.Maybe they would chose music with a bit more of an edge, harder rock, rap and hip hop music. Finally, the third personality group is knows as detached, and they move away from others. Consumers in this group have a need for self-sufficiency and independence and do not need to rely on any one. These are the consumers of many independent bands and singers, who see themselves as going against the grain and against society. Once the consumer base has been segmented into personality groups, it is easier to target each of these groups. Many artists and bands can be advertised in such a way that they can appeal to each of these groups.On the retail level, where consumers are in direct contact with the music industry, there are so many opportunities for consumption, ranging from digital/physical music and concert tickets to festival passes, ringtones, merchandise, clothing lines, band donations and nonprofit initiatives. For instance, when targeting the compliant personality consumer, would be easier to advertise towards since they are very conscious and respondent to others tastes. So, when promoting a new album of Adele toward this group, we would be very insistent with her new songs in all settings.Her songs would be played on all major radio stations, promoted in clubs and bars, and also promoted within social networking which has now become an extrememly important word-of-mouth marketing technique. Now, while reaching out to the detached personality consumer, we would use a different marketing approach. Since these consumers are the ones who are geared more toward indepndent music and anything that is specifically not main stream, there needs to be a careful marketing approach done so that they are unaware they are being advertised too. One idea could be promoting smaller, more intimate shows at local record stores.Also, encouraging these fans to support their local record stores instead of retail chains like Wal-Mart and Best Buy. Since music sales have shifted toward digital downloading mediums, they could reach this consuemer base throught there as well. Another possible tactic could be to create album covers that visual appeal to this consumer base, maybe a loan aritist or a band in darker shades or seperated from society somehow, to appeal d irectiy to this personality base. Finally, the third peronality consumer group is that of aggression. A more tactful approach must be taken when advertising to this market segment.

Robert Henry Lawrence, Jr. Biography

Robert Henry Lawrence, Jr., one of the first black astronauts, entered the corps in June 1967. He had a bright future ahead of him but never made it into space. He began his training and was putting his experience as a pilot and chemist to work as he also trained on  support aircraft. Several months after he began his astronaut training, Lawrence was a passenger on a training flight aboard an F104 Starfighter jet when it made a too-low approach and hit the ground. Lawrence died instantly during the December 8 mishap. It was a tragic loss to the country, and to his wife and young son. He was awarded a Purple Heart posthumously for his service to his country.   The Life and Times of Astronaut Lawrence Robert Henry Lawrence, Jr. was born October 2, 1935, in Chicago. He received an undergraduate degree in chemistry from Bradley University in 1956 and was commissioned a Second Lieutenant into the U.S.  Air Force upon graduation at age 20. He took his flight training at Malden Air Force Base, and eventually ended up providing flight training. He logged more than 2,500 hours of flight time throughout his time in the Air Force and was instrumental in compiling flight maneuver data that was eventually used in the development of the space shuttles. Lawrence later earned a PhD. in physical chemistry in 1965 from Ohio State University. His interests ranged from nuclear chemistry to photochemistry, advanced inorganic chemistry, and thermodynamics. His instructors called him one of the most intelligent and hard-working students theyd ever seen. Once in the Air Force, Lawrence  distinguished himself as an exceptional test pilot and was among the first to be named to the USAF Manned Orbiting Laboratory (MOL) program. That mission was a precursor to todays successful NASA space shuttle program. It was part of the manned spaceflight program the Air Force was developing. MOL was planned as an orbiting platform where astronauts could train and work for longer missions. The program was canceled in 1969 and declassified later on. Some of the astronauts assigned to MOL, such as Robert L. Crippen and Richard Truly, went on to join NASA and fly other missions. Although he applied twice to NASA and didnt make into the corps, after his experience with the MOL, Lawrence may well have made it in on a third try, had he not been killed in the flight accident in 1967. Memorial In 1997, thirty years after his  death, and after much lobbying by space historians and others, Lawrences name was the 17th added to the Astronauts Memorial Foundation Space Mirror. This memorial was dedicated in 1991 to honor all U.S. astronauts who lost their lives on space missions or in training for missions. Its located at the Astronauts Memorial Foundation at the Kennedy Space Center near Cape Canaveral, Florida and is open to the public. The African-American  Members of the Astronaut Corps Dr. Lawrence was part of a vanguard of black Americans to join the space program. He came along early in the programs history and hoped to make a lasting contribution to the countrys space efforts. He was preceded by Ed Dwight, who selected as the first African-American astronaut in 1961. Unfortunately, he resigned due to government pressure.   The honor of being the first black  to actually fly in space was Guion Blufords. He flew four missions from 1983 to 1992. Others were Ronald McNair (killed in the space shuttle Challenger accident), Frederick D. Gregory, Charles F. Bolden, Jr. (who has served as NASA administrator), Mae Jemison (first African-American woman in space), Bernard Harris, Winston Scott, Robert Curbeam, Michael P. Anderson, Stephanie Wilson, Joan Higginbotham, B. Alvin Drew, Leland Melvin, and Robert Satcher.   Several others have served in the astronaut corps, but have not flown in space.   As the astronaut corps has grown, it has grown more diverse, including more women and astronauts with a wide range of ethnic backgrounds.
