growing cheetos
this packet of cheetos I took from guangzhou at normal size, on the train it steadily grew until it seemed like it was going to pop. so the obvious thing was to not eat it and see what happens when I take it another 2000 metres higher up the big mountain. It popped. a good experiment. we also tried taking a packet of cheetos from Lijiang back to guangzhou. except we ate them, so never found out. but i assume they would shrink?
