A solution that really stood out to me was the Q-drum. The Q-drum is a round container that is used to easily transport clean water. It is mainly used in Africa, where it is difficult to find clean water sources. To use it, one simply fills up the container and then rolls/pulls it by using the attached rope. This is a great device to use because water is extremely heavy and carrying it long distances is extremely difficult.
I really like this device because of its simplicity, yet effectiveness. Water is such an import resource but millions of people do not have access to it. It is a source that many people take for granted and don’t realize how many times they make use of it on a daily basis. The Q-drum is a good way to promote social change by giving people the necessities of survival.
