Transcript: FIREWORKS!!! A firework is made out of several component elements. It contains a lift charge, which lifts the firework into the air, a fuse, which lights the firework, the launch tube, which sends the firework into the night sky, then the black powder in the break launches the stars in all directions from the break causing the image you see when the firework goes off. The bang you hear is actually called a report. It is caused by flash powder stored in the break on a time-delay fuse which gets activated when the stars get blown from the break. UNSAFE DO NOT DO THIS EVER EVEN UNDER SUPERVISION NEVER. Fireworks contain black powder, which explodes when fire touches it. When the black powder explodes it usually propels the firework skyward. Safety Tips By Jay and Courtney! History of fireworks -Only use fireworks outside never inside. -Obey all the laws in where you live. -Have water nearby when using fireworks. -stay at least twelve feet away when launching. -DO NOT USE ILLEGAL FIREWORKS OR EXPLOSIVES EVER EVER. Chemical chart of colors. Palm- contains large comets that travel out, explode, and curve down. Round shell- ball shape of colored stars. Maroon shell- makes a loud bang The patterns depend on where the stars are placed inside the shell,and depends on the shepe of the stars. Anatomy of a firework!!! sources -Around 200 BC the Chinese people threw bamboo onto the fie, resulting in a loud bang. -Between 600 and 900 AD the first gunpowder was discovered. It was made of sulfur, saltpeter, honey, and arsenic sulfide. -Around the 1200s fireworks began to be used in warfare. -In 14 or 1500, the Italians developed the first aerial shells -In the 1830s colors were added successfully to fireworks in Italy.

Transcript: Fireworks Pyrotechnics are simply the art of making fireworks. Pyrotechnicians are the people who make the fireworks. Stars are pyrotechnics. They include several ingredients to give them their shine. these ingredients include fuel, oxidizer, color, binder, chlorine donor. Their colors come from the different temperatures of hot, glowing metals and from the light emitted by burning chemical compounds. Chemical reactions propel them and burst them into special shapes. Here's an element-by-element look at what is involved in your average firework: • Aluminum - Aluminum is used to produce silver and white flames and sparks. It is a common component of sparklers • Antimony - Antimony is used to create firework glitter effects. • Barium - Barium is used to create green colors in fireworks, and it can also help stabilize other volatile elements. •Calcium - Calcium is used to deepen firework colors. Calcium salts produce orange fireworks. • Carbon - Carbon is one of the main components of black powder, which is used as a propellant in fireworks. Carbon provides the fuel for a firework. Common forms include carbon black, sugar, or starch. • Iron - Iron is used to produce sparks. The heat of the metal determines the color of the sparks. • Lithium - Lithium is a metal that is used to impart a red color to fireworks. Lithium carbonate, in particular, is a common colorant • Magnesium - Magnesium burns a very bright white, so it is used to add white sparks or improve the overall brilliance of a firework. • Oxygen - Fireworks include oxidizers, which are substances that produce oxygen in order for burning to occur. The oxidizers are usually nitrates, chlorates, or per chlorates. Sometimes the same substance is used to provide oxygen and color. •Phosphorus - Phosphorus burns spontaneously in air and is also responsible for some glow-in-the-dark effects. It may be a component of a firework's fuel. • Potassium - Potassium helps to oxidize firework mixtures. Potassium nitrate, potassium chlorate, and potassium per chlorate are all important oxidizers • Sodium - Sodium imparts gold or yellow colour to fireworks, however, the colour may be so bright that it masks less intense colours • Sulfur - Sulfur is a component of black powder. It is found in a firework's propellant/fuel. • Strontium - Strontium salts impart a red color to fireworks. Strontium compounds are also important for stabilizing fireworks mixtures. • Titanium - Titanium metal can be burned as powder or flakes to produce silver sparks. • Zinc - Zinc is used to create smoke effects for fireworks and other pyrotechnic devices.

Read and follow all warnings and instructions.( Witmer,2010) • Be sure other people are out of range before lighting fireworks. • Only light fireworks on a smooth, flat surface away from the house, dry leaves, and flammable materials. • Never try to relight fireworks that have not fully functioned. • Keep a bucket of water in case of a malfunction or fire.( Witmer,2010) Colors are produced by putting different chemicals into the firework. Blue is created with coppers. Red is created with strontium. Yellow is created with Sulfur. Green is created with barium. You can also create colors by mixing two of these colors. For example you could create purple by mixing strontium and copper. Design Time Delay Fuse Main Fuse Launch tubes in firworks are made of steel and have the same diameter of the firework itself but are three times as long! Stars are what make the show happen. When they are in the firework they just look like a little round sphere. When they are ignited they Create the light and color of the firework. The time delay fuse makes it so you can have more than one explosion in one firework. The timing has to be exact or it won't work. Break A break is like a compartment. It is where the stars are held and where the magic happens. They are made of cardboard and are used to spread out the display. Show Black powder Colors When the black powder confined in the bottom of the firework heats, it pushes at the launch tube until it explodes. Black powder is used in

Color Compound Wavelength (nm) red strontium salts, lithium salts lithium carbonate, Li2CO3 = red strontium carbonate, SrCO3 = bright red 652 orange calcium salts calcium chloride, CaCl2 668 yellow sodium salts sodium chloride, NaCl 610-621 green barium compounds + chlorine producer barium chloride, BaCl2 589 blue copper compounds + chlorine producer copper(I) chloride, CuCl 505-535 purple mixture of strontium (red) and copper (blue) compounds 420-460 silver burning aluminum, titanium, or magnesium Fireworks generate three very noticeable forms of energy: a tremendous release of sound, bright light, and heat. The tremendous booms heard at ground level are the result of the rapid release of energy into the air, causing the air to expand faster than the speed of sound. This produces a shock wave, a sonic boom. The colors are produced by heating metal salts, such as calcium chloride or sodium nitrate, that emit characteristic colors. The atoms of each element absorb energy and release it as light of specific colors. The energy absorbed by an atom rearranges its electrons from their lowest-energy state, called the ground state, up to a higher-energy state, called an excited state. The excess energy of the excited state is emitted as light, as the electrons descend to lower-energy states, and ultimately, the ground state. The amount of energy emitted is characteristic of the element, and the amount of energy determines the color of the light emitted. For example, when sodium nitrate is heated, the electrons of the sodium atoms absorb heat energy and become excited. This high-energy excited state does not last for long, and the excited electrons of the sodium atom quickly release their energy, about 200 kJ/mol, which is the energy of yellow light. I hope that you have a clear understanding of fireworks now...Thanks for watching my prezi and i hope you enjoyed it! :) BOOM!!!!!!
