bright light magnessium

This experiment has to deal with the lighting of magnesium. The process is simple but can cause serious damage to the eyes if looked at directly when lite. The precautions need to be taken is this if you are a girl l(or a boy with extremely long hair) it must be pulled back for you are dealing with fire and you need to make sure that sweatshirts and long baggy clothes are either not worn or pulled, because you will be dealing with fire. Then the next thing you need to get is protective glasses in case anything shatters while doing the experiment The items needed for this experiment is a Bunsen burner preferably two small strips of magnesium a small claw pot and rack to hold the pot in. You also need a lighter or a flint and gas but it would be best you went to chemistry class for all the items. The first step is to measure the clay pot for its mass. The second step in this expirement is to get the two tiny magnesium strips and twist them together. Then you need to have the claw pot on the rack and put it over the Bunsen burner and turn on the gas. You then need to light the gas and to make sure that there isnt to much oxygen and the flame isnt to high. After that you place the magnesium in the pot and put the lid on. You leave the lid on for about two to three minutes. The reason why you do this is to see if the magnesium will light ignite and show a bright light if it doesnt within the time period you take off lid off and wait again. If it doesnt ignite again then this is when you have to phisycally light it yourself. What you do it take some tweezers, but these arnt ordinary tweezers they have to be long, and you take the magnesium and put it in the flame until it lights. You want to make sure that you do not look at the light for it can damage your eyes. After it lights you have to put it back in the clay pot, have your partner help you with this in case you miss. After you put the magnesium in the pot you have to shut off the gas, because the heat from both the fire and the magnesium could shatter the pot (this is where the protective goggles come in). After the light goes out you take the pot and weigh it again for its mass. If the expirement was done correctly then the mass should have increased and the magnesium should have lite. When you are done writing down the mass of the pot with the magnesium you now have to clean up. What you do is make sure that magnesium is cool so when you throw it in the trash it wont melt and after that you put everything away.
