Recommended: When did glow sticks become more popular
Glow sticks started when scientists tried to replicate the natural bioluminescence, the light emitted by organisms such as fireflies. In the 1960's Edwin Chandross of Bell Labs patented the first glow sticks out of oxalyl chloride and hydrogen peroxide. Building on "Chandross' discovery, a team from the labe called American ?Cynaamid led by Michael M. Rabut created an oxalate ester named pehenyl oxalate to replace the oxaly
This experiment was conduct to investigate the fluorescent behaviour of Leucophor PAF and to investigate the quenching of QBS with NaCl. It was found that the Leucophor PAF indeed satisfied the characteristic to act as whitening agent. It was also found that the quenching of QBS with NaCl was a diffusion-controlled collision process.
Glow sticks were first made in the 1960s when a scientist, Edwin Chandross tried to copy fireflies. He thought it was fascinating how they gave off a natural light. He made the first glow stick from oxalyl chloride and hydrogen peroxide. Since Edwin’s invention many scientist after made improvements to the invention. The United States Navy worked on creating glow sticks independently and received a patent in 1973. Glow sticks started to become popular in the 1980s and since then are still very popular today. The largest glow stick was made in 2009 and was 8ft 4 inches tall. Glow sticks can be used for entertainment when dancing they are very popular for raves, parties, night clubbing, special events etc. glow sticks are the safest light sources in emergencies, They are used because they are very efficient and do not require any batteries or electricity. Glow sticks are portable and waterproof can bear high pressure situations and that is why military forces and campers use them and have them on hand.
In 1928, an accountant, Walter Diemer, invented an improved version of bubble gum. The only food coloring he had on hand was pink, so for many years, pink was the common color of bubble gums. Diemer arranged to market the bubble gum in Philadelphia candy stores and the product became wildly popular with children. Fleer Company purchased the recipe, and named the product Dubble Bubble.
Since the 1930's, plastic pink flamingos have been a trendy statement piece at hotels and in yards across the country. Jennifer Price, the author of "The Plastic Pink Flamingo: A Natural History", uses tone, satire, and diction to show her view on United States culture. Price's view is that United States culture is flashy, cocky, and that Americans tend to try and stand out to get attention.
WHO INVENTED IT: The people who invented the jolly ranchers were Bill and Dorothy Harmens.
Controlling chemiluminescent light was how Omniglow Incorporated became the first company to produce light sticks. In 1986, when the first light stick was invented, scientists thought they could make a lot of money selling light sticks. However, since they had to make light sticks by hand, it was harder for them to produce very many of them. Until machines were invented to make light sticks, it cost too much money to make them by hand.
Let's look closer beyond the simple answer to the question of who invented the Pink Plastic Flamingo, let's look into the story of its legacy...
Thomas Edison was one out of six children born to Samuel and Nancy Edison in Milan, Ohio (DeMauro). Edison lived for a total of 84 years, and in those many years, he produced a large variety of different inventions that still affect our world to this day. Among his many inventions, the most well known ones consist of the lightbulb, the phonograph, and the kinetoscope.
This experiment synthesized luminol (5-Amino-2,3-dihydro-1,4-phthalazinedione) and used the product to observe how chemiluminescence would work. The starting material was 5-nitro-2,3-dihydrophthalazine-1,4-dione, which was, after addition of reaction agents, refluxed and vacuum filtered to retrieve luminol. Using two stock solutions, we missed our precipitated luminol with sodium hydroxide, potassium ferricyanide, and hydrogen peroxide, in their respective solutions, in a dark room, to observe the blue light
Before lights were placed on trees, candles were used instead. It is widely believed that Martin Luther, the 16th Century Protestant founder, first added candles to trees. He was walking home on a winter night while writing a sermon, when he saw the stars shining above the evergreen trees. He noticed how beautiful the view looked, and in order to recreate it for his family, he placed lighted candles on his family’s Christmas tree. An inventor named Edward Hibberd Johnson hired Thomas Edison, then a 24 year old inventor, who later created the lightbulb. After Thomas Edison patented the light bulb in 1880, Johnson invested money in Edison’s bulbs and later used them to fashion Christmas lights. He recognized that candles are a fire hazard, and lights would provide a safer alternative. Johnson wired 80 light bulbs of three colors and strung them around his tree. The beautiful, bright tree attracted newspaper reporters and pedestrians who continued to come back each year. In 1894, President Cleveland put lights on the White House tree for the first time. The first set of lights was released to the public in 1900 and priced at $12 or $350 in today’s money. In 1914, the sale price for a 16 ft string of lights decreased to $1.75. Today, 150 million light sets are sold, and 80 million homes are decorated each year which equates to 6% of the United State’s electrical load each
Roentgen realized that the cathode rays couldn’t cause this reaction, because the screen was too far. He theorized that invisible rays that came from the Crookes caused the fluorescent glow. Later, Roentgen discovered that these rays were capable of penetrating a few objects. He decided to use the rays on his own hand, and he was able to see the contrast between opaque bones and the translucent flesh. He found that the rays could pass through human tissue, causing bones and metals to be visible. Instead of using a screen, Roentgen used a
The ingredients that will be included are: dish soap, 30% hydrogen peroxide, potassium iodide, and corn starch. Adding the cornstarch to the mixture has a chemical reaction to the hydrogen peroxide. It will have light and dark patches due to the uneven placement of the cornstarch; it will have an uneven reaction. Which will then make it appear “glowing”. The fourth experiment is very similar when it comes to the ingredients the only thing that changes is that we are no longer using potassium iodide but we are using yeast instead. Also, since yeast is being used, we are adding in fluorescent dye to it so we can shine a UV (ultraviolet) light on it to see the reaction occurring. Using the dye under a light helps us observe the reaction between the dye and cornstarch. I had to replace the potassium iodide with yeast for a slow reaction and also so it is possible to use the dye. In both of these experiments the reaction is a massive production of foam. The hydrogen peroxide will be decomposed into water and by the oxygen by the iodide and/or the yeast. A substance called catalyst speeds up the

Traffic lights are signaling devices located at road intersections and pedestrian crossings, they are now part of our everyday life. Before traffic lights were invented, policeman would control traffic, but accidents would still occur frequently. This is when J.P Knight took action in 1868 and made the first traffic light. It was installed outside the British Houses Of Parliament but didn’t last long since it exploded in 1869 due to a gas leak. It was only in 1912 that a man named Lester Wire created an electrical traffic light that is still used today. There are three main types of traffic lights: fixed timed, semi actuated and fully actuated. Fixed time traffic light are light where “signals change according to a pre-set timing. The signals will cycle all the time even if there is no vehicle or pedestrian demand.” (a). In semi actuated signals vehicle detectors and push buttons are installed on streets and roads. The traffic signals will remain green until either a group of vehicles is detected or a pedestrian pushes a button. Lastly in fully actuated lights “ signals are programmed to change with minimum green times depending on the traffic and pedestrian demand on all approaches. The signals will change based on the demand from each approach.” (b).
Thomas Alva Edison is a very well-known American inventor. He invented about 1093 devices that influenced us greatly, such as light bulb, microphone, telephone receiver, universal stock ticker, phonograph, kinetoscope (used to view moving pictures), storage battery, electric pen, and mimeograph. Edison also improved many other existing devices as well. In the period from 1878 to 1880, Thomas Edison began serious research into developing a practical incandescent lamp. Edison and his associates worked on at least three thousand different theories to develop an efficient incandescent lamp. In 1878, Edison built his first high resistance incandescent electric light. Incandescent lamps make light by using electricity to heat a thin strip of material (called a filament) until it gets hot enough to glow. Many inventors had tried to perfect incandescent lamps to "sub-divide" electric light or make it smaller and weaker than it was in the existing arc lamps, which were too bright to be used for small spaces such as the rooms of a house.Edison's lamp would consist of a filament ho...
