Methods and materials
My methods and materials are:
1) Obtain the following equipment:
-5 plastic cups
-100ml non-medical methylated spirits
-100ml vinegar from the kitchen
-100ml salt water
-100ml plain water from the kitchen tap
-100ml olive oil
-5 identical iron nails
-1 tray to hold utensils on
2) Pour each of the 5 liquids into a plastic cup
3) Place an iron nail in each cup
4) Place cups on tray in a shaded room-temperature environment
5) Observe any changes during a period of 3 weeks
6) Record an observations made
7) Repeat steps 1-5 to ensure a fair experiment is undergone
8) Clean up?
I'm not too sure whether leaving them in the sun or shade makes a difference to the rate at which the iron nails will rust but as far as I know and think, I don't belive so. However, I will attempt to keep the tray in a shaded room-temperature environment as much as possible.

It's been 41 days since my last post -_-. During that time, I've set up my experiment 4 times. Something just has to happen...
1st Mum poured out the liquids accidentally down the sink because she didn't know
I had SRP.
2nd The tray was on my glass table and my elbow knocked my laptop case which
knocked the tray. All liquids besides the oil were soaked up by my rug. Cups
broken.
3rd Dad soon realised he gave me different types of nails though they looked the
same.
4th Currently undergoing! Hope all goes well...Now using clear plastic cups and
all iron nails =D
The longest attempt I have undergone was my 2nd attempt at the experiment. If my table wasn't messy, the experiment would have survived...During that attempt, I did not notice any discolouration or changes to the nail.
