We did an experiment to test the importance of soap in washing our hands. Washing our hands properly has always been important but even more so since the arrival of Covid-19. We used clear plastic tubs, tap water, pepper to represent germs and anti-bacterial soap. We found that when we just used water, the germs stuck to our hands. When we used soap, the germs were pushed away and did not stick to our hands. We will always use soap to wash our hands properly!
