[Free Talk] A round bag of yogurt

I bought a bag of yogurt  that was in cold store yesterday in a supermarket nearby my dwelling,I put it on desk without chilling and plan to drink it on the day.But in fact I forget that I need to drink up it and on the second day I find the bag which should be flat all the time become a round ball.What strange is! The first time I see such an odd phenomenon in my life.I think it's degenerative and intend  to put it as an interesting ornament on my desk until the bag ruins totally.You can see the following pictures,that's amusing.[s:267]
