How Permanent Are Permanet Markers

For my science fair project, I figured out what solvent would work best to erase permanent marker. The solvents I tested were: lemon juice, vinegar, water, and rubbing alcohol. I tried each of these solvents on a permanent marker line on plastic, paper, fabric, and wood. In this research paper, I will be talking about what a permanent marker is, how they are made, why they work so well, what rubbing alcohol is and its common uses, what vinegar is and its common uses, what water is and why water is so essential, and what exactly lemon juice is. I will also be talking about how plastic is made, how fabric is made, how wood is made, and how paper is made. A permanent marker is a type of writing utensil that is used to create permanent lines…show more content…
The solvent that worked best in my experiment was rubbing alcohol. Rubbing alcohol is a denatured alcohol especially used as an antiseptic. It can also be used to cool, warm, or soothe skin. It can inflame the skin and if ingested, may potentially be fatal. Rubbing alcohol consists of 2 ingredients: isopropyl alcohol and water. In fact, rubbing alcohol consists of so much isopropyl alcohol (70%) that it is often referred to just as isopropyl alcohol. Water was the final solvent that I used in my experiment. Water is essential for anything and everything. Human beings need water to stay hydrated and survive. All living creatures need water to stay hydrated and survive. Everyone uses water every day; whether it’s to shower, brush their teeth, to drink, swim, wash their hands, or to water plants. Seventy percent of the world is made up of water. Water contains two hydrogen atoms and one oxygen atom, and is often referred to as H2O. The H2 stands for the 2 oxygen atoms and the O stands for oxygen. Water can be a liquid, solid, or gas. Water in its regular state is a liquid, can be frozen to form ice, which is a solid, or boiled at 100° C to evaporate it and turn it into water vapour, which is a gas. Plastic was one of the surfaces I used in my experiment. Plastic comes from the Greek word plastikos, which means fit for moulding. Plastic is made using a long and complicated process. First, petroleum is
