The first step of rusting a nail is to put a nail in the water and it will take it a while to rust in a short period of time, Open the window if you have one and the nail will get fresh air and pour equal amounts of vinegar. The second step of rusting a nail is to rub the nails surface with sandpaper and it will remove rust proof layer on nails, keep the nail in the water for half an hour if not an hour, when the time is up remove it from the water take the nails out of the water and put the nails on a paper towel. Put the paper towel in direct sunlight for one or two hours. The heat from the sun accelerates rust formation on the nails. Then repeat soaking the vinegar and dry them to get the nails to rust faster. The definition of rust is a reddish- or yellowish-brown flaky coating of iron oxide that is formed on iron or steal by oxidation, especially in the presence of moisture. The hypothesis of how to rust nails is I think there are multiple and faster ways to make nails rust. Another way to make the nail rust faster is to put the nail in salt water. The reason why the nails need water is because, water and oxygen react with the iron. There is no way to rust nails in the sunlight, it needs that water and oxygen to make the rust form. The materials that can be used is bleach, glass container or a bowl, white vinegar, or apple cider vinegar. The reason why people use water to rust is because water is one of the most common liquid substances that are rich in oxygen which causes the nail to rust **(Dependant Variable)**. Sea salt with water speeds up the nails rusting speed. The nails need all of these things and materials to make the nail rust quicker than usual **(Independant Variable)**.


 * Conclusion**
 * The better way to rust a nail is to use bleach and the nail will need air for the nail to rust. The nail on the first day I started was a regular iron nail and it was starting to get darker on the second day of the expirement.**
