Screenshots of the short videos that the influence agents could spread among their peers. The short videos were made by the researchers. The first screenshot is from a scene where a child talks about the environmental benefits of drinking water. In this scene, the child explained that if more people drink water, less plastic is made in the factories because you can drink water from the tap. This allows less plastic to end up in the plastic soup in the North Pacific Ocean. The short videos also included other benefits of drinking water, including that water contains no sugar and has zero calories. All these benefits correspond to the ones discussed in the presentation during the training and were suggested by the children themselves
