We agree with WSJ’s Sky Canave’s observation about the sad lack of food options on the Olympic Green. McDonald’s, being an official Olympic sponsor, was the only restaurant on the Green (sad, isn’t it?) and if you didn’t want to bring yourself so low as to step into a fast food restaurant like we did, the only other options really were instant noodles (mmMMmm yummy!) and this exploding lunch box that you see here, available for RMB20 and in a range of flavours. The idea behind the self-heating box is really very simple and akin to those pocket warmers that people use in winter. You just have to be very, very careful when it goes off because we heard quite a few people got scalded that way. Anyone seen this around anywhere in Shanghai?
