Analyze Candy Using Chromatography

Step 4 of 9: Add water and wait

Add enough water to the cup so that it touches the bottom of the crime scene 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. Remove the crime scene filter paper from the water and allow it to dry.
