Analyze Candy Using Chromatography

Step 7 of 9: Hang the filter paper and add water

Poke a toothpick through the top of the filter paper. Rest the toothpick on the edge of an empty glass so the filter paper hangs down inside. Repeat with the other filter paper. Add enough water to each cup so that it touches the bottom of the filter paper but does NOT touch the candy smudge. Allow the water to rise up the filter paper, which causes the candy smudge to spread out. This will take a few minutes.
