Helpful Tip: Only use 4 colors max per coffee filter. If you want to experiment with more than 4 colors then use multiple coffee filters. Step 3 — Pour one inch of water into an empty glass and add one teaspoon of salt.
Stir until the salt is combined. Step 4 — Shape the coffee filter into a cylinder and place it into the glass. The bottom of the coffee filter should just touch the water. Then take a few minutes to make some observations. Do you notice anything happening with the water and the coffee filter? Let the glass and coffee filter sit for 30 minutes to an hour and then come back to see what happened.
Step 6 — When you return to the glass, what has changed? Carefully remove the coffee filter from the glass and set it flat on the table. Observe what has happened to the colored circles. Do you know what caused the colors to spread? And why some of the colors stayed the same, while others changed? Find out the answer in the how does this experiment work section below.
Over the course of the hour, the coffee filter gradually absorbs water. The coffee filter is able to absorb water through the process of capillary action.
