How to Make a Giant Bubble Using Dry Ice

All you need to make this giant bubble is dry ice, bubble solution, and either a little water or else tonic water and a black light (glowing liquid). You can make the bubble itself glow if you add a little highlighter ink to the bubble solution. The dry ice sublimates to form carbon dioxide gas, which expands the bubble.  Watch the video tutorial of this project. Materials dry icebubble solutionwater (or tonic water and a black light, if you want glowing liquid)glass or dish Make a Dry Ice Bubble Pour some water or tonic water into the container.Add a piece of dry ice. The dry ice will make bubbles in the liquid.Spread a film of bubble solution around the lip of the container.Use your hand or a piece of paper towel that has been wetted with bubble solution to smear bubble solution across the top of the container. I made a video of the project so you can see what to expect. How It Works Dry ice sublimates in air, meaning the solid carbon dioxide makes the transition to carbon dioxide gas. This process occurs much more quickly in water than in air. As the dry ice sublimates, the carbon dioxide vapor is caught inside the bubble solution. The bubble expands, but the cooled bubble solution does not evaporate quickly so the bubble lasts for a relatively long time. Sometimes conditions are right for the bubble to stabilize at a given size. This happens because carbon dioxide is able to diffuse across the bubble surface. Sublimating carbon dioxide expands the bubble, but when the bubble expands its walls become thinner and leak more. Since more carbon dioxide can escape, the pressure is reduced and the bubble has a tendency to shrink back again. As long as the solution doesnt evaporate too quickly, the bubble may remain relatively stable until the dry ice is nearly gone. At that point the bubble will become smaller.

Lucky Charm free essay sample

â€Å"The things they carried† is a story about couple Vietnam veterans who carried different items with them with their reasons why. We all believe in one thing or another. It is all about what you thinks works for you and how it works. Personally I have been carrying a coin that I have on me at all times. The coin has been in my family for over two hundred years. My great grandfather got the coin from a customer when he started his export business in late 1850’s in Kabul, Afghanistan. It was the first money that he made when he was in business. About 250 years later and I still have the coin and I will pass it on to my son. Because the first son born to the eldest son gets to keep it. I have been very lucky and honored to get the coin and get lucky. Yes it sounds a little crazy but if you really believe that it will work and will bring you luck and success it definitely works. We will write a custom essay sample on Lucky Charm or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page I was 17 when I got the coin I had heard stories about it because my father would tell me like how he got it and how much luck and success it brought to him. It is a Shanzi; quarter Afghani which is made out of pure silver. They stopped making them in the early 20th century because people start misusing the coins. The amount of money that was spent on the silver coins to manufacture was more than the coin itself was worth. Ever since I got the coin I feel that I have been lucky and successful. Right after I got the coin I got in a big car accident and I was hospitalized for almost two months. My car was damaged so bad that everyone thought I was not going to make it. But I guess my time was not over yet. In the beginning I was a little iffy about the whole coin thing, but the accident changed my point of view and I started believing that this is my lucky charm and my guardian angel. There was something that made me feel that my ancestors were watching over me. Just like me there are many people who carry one thing or another as a lucky charm or as protection. I think if you are not a strong believer you might not get attached or start to believe in it in the beginning until something devastating happens and you survive it. For some people it is a part of their religion and some see it as an accessory. For example back in the days people used to wear a cross for religious reason and nowadays it is considered a MUST have accessory. Especially for the younger generation it has nothing to do with religion. I read an article on Yahoo about a month ago which covered the same topic. â€Å"What and why do people carry stuff on them? † People carry some things that are beyond belief, but at the same time amazing. In the end it is all about what gives you the reason and if you believe that any particular item will work as a lucky charm I don’t see why you shouldn’t carry it.

Social Security Essays - Economy, Finance, Income Distribution

Social Security Social Security is a hot topic of debate today, since most American's believe that the system is near collapse. The trust fund that Americans have been paying into for Social Security is likely to dry up in 2029 due to the large number of baby boomers heading into retirement. Franklin Roosevelt set up Social security to help the people that had worked and Struggled all their lives in honest toil. Social security was set up to accomplish two main goals. The first goal of Social Security is to act as a disability or life insurance policy that protects almost all Americans. Currently, there are seven million survivors of deceased workers and four million disabled Americans that receive income support from Social Security. The second goal is to provide lifetime retirement benefits that rise with inflation. Social Security payments for retirees are needed to keep half of the elderly Americans above the poverty line. A large number of baby boomers believe that they won't see a dime's worth of Social Security benefits, and most younger people assume that once they have reached retirement the program will be gone. There have been many proposed solutions to the Social Security problem. A first possible solution is to dramatically change the Social Security Payroll Tax. Another proposal is to change amount of benefits of the provided by Social Security. A third reform proposal includes investing Social Security money in stocks either by the government investing the money or by setting up mandatory IRA investing. Another major development in the future of Social Security is the recent proposals made by President Clinton's Advisory Committee on Social Security. In January of this year the Advisory Committee on Social Security presented a report of strategies to save Social Security. Shortly after the 261 page report was released there was a huge increase of debates and criticism over the future of Social Security. The issue facing American today is when and how to reform Social Security. Although the American public and political groups are unwilling to accept the burdens of social security reform, extensive reform is needed soon to continue paying the current benefits to American citizens. A change in the Social Security tax is a possible factor of reform to bring the Social Security program back on track. Currently the Social Security tax is a flat-rate tax paid on all employment earnings up to a specified limit. Due to inflation the limit is increased every year currently it is just over $60,000. This tax is much harder on a lower income individual because the higher income individual is only taxed on their income that is below a certain amount set every year. It has been proposed that if the limit on the payroll tax were lifted, two-thirds of the projected Social Security deficit would be eliminated. Once the limit on the payroll tax is lifted a rise in the tax rate of the employers and the employees by 1.1% is predicted to be enough to solve Social Security's problems. This is assuming that two evasive actions take place. First the government will have to keep its hands of this extra tax revenue gained by the tax increases. Second the proposed solution will only have a chance to work if it is started immediately while the baby boomers are still able to add a little more cash to the trust fund for there own retirement. This solution isn't likely to be implemented by today's political system. The advisory council on Social Security would not pursue the lift of the limit because the support of the wealthy voters for Social Security reform would be lost. Americans are also weary of Social Security tax increases. The middle and lower class voters would also not support a Social Security tax increase. A recent poll by Money magazine found that 70% of the public is unwilling to pay more tax than the current 6.2% rate. Another proposed solution to Social Security's problems is a to decrease the amount of benefits received by retirees. The first way to reduce the amount of benefits that are being paid out is to adjust the CPI. Sen. Daniel Monynihan of New York (Dem.) has proposed that a 1.1% cut in annual cost-of-living adjustments for pensioners would be a reasonable solution to Social Securities problems. The adjustment of the CPI would reflect the belief by many economists that the CPI overstates current inflation. He claims that this would almost completely solve the problems in the Social Security program by insuring that the expected inflow
