Seed Germination Testing ("Rag-Doll" Test)
Use a firm paper towel such as a brown hand towel or equivalent (the soft, very absorbent paper towels often used in a kitchen make poor rag dolls because they allow roots and shoots to penetrate into the fiber, making seedlings difficult to remove during counting). If no other type of towel is available, the soft towels can be used, but it is best to use a double layer.

The Scientific Method | Experiment
Experiment | Overview For our problem, we need to create a test that will determine whether or not Brand A paper towel will absorb more water than Brand B paper towel. Our experiment consisted of measuring water, folding a paper towel, dipping it into water, noting how much water it had absorbed and then repeating the process with the other brand of paper towel.

Science Project
Purpose The purpose of this experiment was to see which brand of paper towel most absorbent for consumers. I became interested in this idea when I got looking on the Internet for project ideas.

Conservatree
In April 1996, consultants Nancy VandenBerg, Susan Kinsella and Carla Lallatin produced Resourceful Purchasing: A Hands-On Buyers' Manual with How-To-Do-It Guidance for Source Reduction and Recycled Products for the Alameda County Source Reduction and Recycling Board. Nancy VandenBerg, principal of Markets for Recycled Products, was the project lead.

Measuring Paper Towel Absorbancy
The way you would find the absorbance is to perform an experiment. When a scientist has something he does not know, he performs an experiment or series of experiments to determine the answer.
