The document summarizes an experiment comparing the absorbency and price of 6 paper towel brands. Students tested each brand by dropping water from an eyedropper onto a folded square and measuring the diameter of the absorbed area. Bounty was the most expensive at 6 cents per sheet but absorbed to a diameter of 11 cm. Scott had the lowest price of 1 cent per sheet and the second largest absorption area. The document concludes that Scott is the best value brand based on its low price and high absorbency.
