Method
To start off the experiment, each plastic container, except for one, was filled with a substance. The plastic sleeve and the sheet of paper were cut into four equal rectangles. The paper was then slid into the plastic sleeves and taped together to ensure when they were placed in the substances, the liquid would not seep through and wet the paper.

Each colour of nail polish was then applied to the sleeve in a single stroke, measuring exactly five centimetres. The white background allowed the colours to stand out and made it easier to notice the changes during the experiment. The nail polish was applied to all four sleeves and then left to dry.

After the nail polish had dried, each sleeve was placed in a container. The sleeve was placed right at the bottom of each container to ensure it was completely covered by the substance. The three containers, which contained the liquid substances, were kept indoors. One container was placed outdoors, where it was exposed to the rain and sunlight. The results of what had occurred by the end of each week were recorded in a log book and blogged about. To note the results, each sleeve was visually investigated and to determine how much nail polish had disappeared, a ruler was used to measure these changes.
