​

• Which paper had the least streaming of the color band?

• Which paper had the most streaming of the color bands?

• Which paper showed the best color separations?

• Which paper would you use to do other tests of this kind?

• Do you think the results would be different if we used coffee filters instead of paper towels? Explain.
