By using the fruit Peel include bergamot Peel Lemon peel Grapefruit Peel Tangerine peel came to rub the area with a fluid Word. The results it appears that Roy the wrong fluid can be removed to. Make the area cleaner and economical and safe for users, too. AcknowledgementsThis project, well done, thank you, teachers, State, Phong phongsa pan that provides advice, counselling and education about science and to do the work, thank the Director of education that provides help and information about exhibits, design, material science, courtesy, and equipment used in the experiment, as well as the materials used in the exhibit, thank you to those who give the knowledge from this project go to the teaching and learning of science, as well as thank the parents and colleagues to cooperate as well.Chapter 1IntroductionOrigin and importance.In the current economic conditions we have experienced the problem. Many of you probably know that the country's economy plunging Thailand into an alarming rate the consumer product prices in the market are rising along with it. Make these merchants and citizens faced the problem of goods and merchandise sales or lack of stock, making the more expensive price for goods. Which people are maid Butler wormwood with standard household expenditure that must be increased, but revenue, expenditure, there are also the same. Therefore, we discuss and find a solution to help Butler and Maid, household expenditures are reduced? , Which must start from the things we use every day and consumes very much like cleaners that we use every day, and that's why we've expensive invention of artificial methods, experimental studies and cleaners eliminate the lessons from the fruit Peel for their own use, reduce household expenses by Dai.A little one, it's still good. Water education and eliminate the peninsula we have brought this proposal has come from natural raw materials within the household and local. Not dangerous, plus to make saving money to get more. How to make a liquid, eliminating the lessons! Just you father a house maid or people who are interested in education and used to do can be done by yourself, plus, when we have knowledge can be done successfully, then we might be able to share knowledge with people interested but didn't have time to study the document. From the above mentioned reasons and information. Make us who are interested in occurs, try the cleaners eliminate lessons from citrus fruit peels away by market or fruit on the tree have a lot until the leftovers. The assumption Citrus fruit peels can remove fluid (liquid paper).The aim of the research 1. to study the leading fruit Peel used to scratch the wrong fluid on the table.2. to use waste benefits the most.3. in order to bring the process of scientific applications benefit themselves and mix.4. to encourage creativity, to practise their own scientists. Scope of the research Organizational matters Delete a mistake fruit Peel Those studies have defined the scope of the study, people grab. 1. scope of content -Indication of bergamot, lemon and Mandarin orange, grapefruit, -A list of the equipment and chemicals. -Experimental method.2. the scope, period Those studies have used the period of studies is from July to October, 2557 2557 (2014)Bring the fruit Peel 4 kinds of experiments, Kaffir lime and tangerine peel, grapefruit, by rubbing the crack fluid (liquid wallpaper: liquid paper) that tracks wood desk and Chair to compare the ability of the wrong fluid Liquide landowner poe (liquid wallpaper: liquid paper).Definitions and terminology1. the wrong fluid means a liquid or a solid white is used for the label slash error message in your document and, when dry, this can be overwritten. Typically, the wrong fluid is contained in a small bottle and caps which are trapped (or it could be a piece of the foam triangle) that dip cleaners are in the bottle. Brushes are used for labels on cleaners. Before the invention of word processor Fluid is very popular for printing documents with a typewriter. The earliest forms of the wrong fluid, established when the 1951 by the Secretary. Bette Nesmith Graham, founder of liquid paper with white filling into the nail polish bottle. Use a paint brush cleaners, white label the printed word on paper.1. paint thinner because the wrong fluid contains organic solvents (volatile organic compounds). Solution is not used for a long time to concentrate more on time because the solvent will evaporate into the air, which may make it too concentrated cleaners are used, or perhaps it haengkrang go! Therefore, the manufacturer of fluid, some wrong, so selling the solvent to another bottle, separately called the thinner. To put a few drops of paint thinner into a bottle, it makes the normal conditions comes as namyaklap, thinner that the original contains toluene, which is banned from use due to carcinogens. Later changed to 1, 1, 1--Chloroprene trilogy e-ten, but was banned again by the ceremony of anot sarom (Montreal Protocol) because it is the substance that destroys the ozone in the atmosphere. So change to Tri-ethylene chlorophyll which just aren't safe from much higher. Currently, the thinner is used in correcting cleaners contain bromo propane. In order to avoid inconvenience to use organic solvents for reasons of security and recruitment. Certain brands of fluid can be used as a solvent, but it has the disadvantage that take longer to dry, straight and does not apply to certain types of ink, which will cause the ink with a liquid,
