This was a super easy experiment to do.
We filled one glass with water tinted with food coloring. You don't need to tint the water, but it makes it easier to see the water move.
We took a 1" strip of paper towel and dropped one end into the cup filled with water and the other end into the empty cup. Then we watched the water move up the paper towel.
The paper towel absorbed the water and transferred it into the other cup.
We also tried 3 glasses, 1 empty glass, 1 glass with blue water, and 1 glass with yellow water. The water also went up the paper towel and into the empty glass.
