On the fifth day the participants continued to work on their prototypes in teams. The visit by some participants to Yuzhnoye Medvedkovo on the previous day resulted in some amendments to the prototypes. On this day several other team members went to the neighborhood together with Michiel to do some additional testing of their ideas and to arrange buying materials. To our surprise very few people in the park wanted to cooperate in the testing of the prototypes. On previous visits people seemed much more willing to engage in conversation. It could have been the early hour or the treat of thunder and heavy rain showers looming over Moscow. In any case it proved to be a good lesson in thinking about how to communicate to people in the neighborhood.
