Do you use water or alcohol to make the radial chromatography designs
from the black markers?
Just wondering so I can use this in my classroom,

My all-time favorite is water with "Mr. Sketch" black scented markers. What grade do you teach? Send us pictures of you and your students working with chromatography and I'll include them in Thinking Fountain. -karen
