TRIAL 1
TRIAL 2
They're identical! The two trays are set-up in my room on my table, which is so messy as you can see, and the tray helps prevent me from knocking the cups over and spilling the liquid on my table.

New addition!!
I forgot to mentio previously that I am not using 20 nails in total for the 2 trials, instead of the previous idea of using 10.
I'm using 10 nails for each trial; one submerged and one emerged, because it would provide me with more accurate results and a wider range of results so that I can make conclusions more easily with evidence. Therefore, the aim of my experiment has altered a bit. The aim of my experiment is "To observe whether iron gun nails rust faster submerged or emerged in liquid, and in what liquids."

Results
I have completed two trials of my experiment. So far, the results are uniform across the two trials. In each cup for each trial, there were two nails. One nail was submerged in the liquid and the other was exposed to the air. In both trials, the nail exposed to the air rusted more and rusted faster.
I left the two trials to sit for 7 days exactly and vinegar was the liquid to show the most pocitive and the most signs of discolouration and rusting. In this experiment, I used white vinegar and by the third day, the white vinegar had turned an off-orange due to the rust of the nail.
I used 5 liquids; vinegar, tap water, salt water, methylated spirits and canola oil. The liquid which had the least effect on the rusting of the iron gun nail was the canola oil. Being a spirit, the methylated spirits began to evaporate by the third day. It completely evaporated by Day 6.
