Here’s an excerpt of Alex’s experience:

The biggest accomplishment that our group achieved while volunteering was the introduction of toothbrushes to the slum children. One afternoon we went to the local market and bought 40 toothbrushes, toothpaste, and a lot of hand sanitizer. The next day we came to the slum and gave each child a toothbrush. Before their snack we got them all to wash their hands, and after their snack we had them all line up and brush their teeth.
