Dormitory of cool ideas: Electric fans, air conditioners… colleges offer their students a range of facilities to keep cool. But it seems like it’s still not enough, and students are coming up with their own ways of cooling down. Recently, students at Huazhong Normal University in Wuhan have been using small, inflatable swimming pools to cool down inside their dormitory rooms. The pools cost a few hundred yuan and take one hour to fill with water, but the enjoyment of playing cards and surfing the Internet in comfort is worth the effort. CFP
