Today, Thinker Raavi walks us through a step-by-step tutorial on how to make chromatography art!
chro·ma·tog·ra·phy
[kroh-muh-tog-ruh-fee] the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates. Deriving from the Greek word for color, chromatos, chromatography entails separating a substance through a medium. The word was originally used describe the separation of plant pigments. Chromatography is used in the fields of biochemistry and analytical chemistry. Today we will be using water (or isopropyl alcohol) to separate the different pigments in a marker.
What do I need?
- 1 coffee filter (or paper towel)
- Markers
- 1 empty cup
- 1 cup with water (or Isopropyl alcohol)
- 1 eyedropper
- A space for your art to dry
Step 1: Make a cool drawing with your markers.
Leave at least a little white space for your colors to spread.
Step 2: Place the coffee filter on top of your cup. 
Step 3: Fill the eyedropper with water (or isopropyl alcohol).
Drip the liquid over the filter and cup. 
Step 4: Set the filter out to dry. 
Then, once it’s dry, find a spot to display your awesome art!
