Carol, the dairy owner, is considering switching to reusable cloth towels (instead of paper toweling) to clean cow's udders. She brought in three different types of towels for Jody and I to try: two were white w/ a green stripe, two all dark green, two all white. Jody and I used one of each as we worked. Wanting to capture all input, I got a white board and wrote comments we made about each type of towel preceded w/ little "+"s and "-"s, used a different color for Jody's comments vs. mine, noted which cows we used, and finally, which towel Jody preferred and which one I preferred. I love a good experiment!
