Chen Yun-chung says that it occurred to them that it might be dangerous for the kids to cut styrofoam, so while they were looking for suitable modeling material for children, they especially prepared cookies, cauliflower, straws and modeling clay. They even rehearsed the decision-making procedure in advance, the students all playing the roles of members of the community, to make the whole process come together more smoothly.
陳允中說，因考慮到小孩切割保麗龍有危險性，他們在尋找小孩適用的模型材料時，特別準備餅乾、花椰菜、吸管、黏土等；還很周到地事先預演實驗，分飾社區內的各種成員，以期溝通能夠更為順暢。
