Without Soap

When I tried to scrub my hands clean of the coffee grounds and cooking oil without using soap, not much washed off. The water alone had very little effect on the mixture on my hands, and I did not see any improvement until I used a paper towel to pat/rub my hands dry.

With Soap

When I tried to scrub my hands clean of the coffee grounds and cooking oil using hand soap, there was a noticeable difference. As shown in the previous slide, the water alone had very little effect on the mixture, but when added to hand soap, my hands were virtually spotless. The coffee grounds were almost completely gone and there was essentially no cooking oil left on my hands.
