This is an Interesting advertising invention worth mentioning. You don’t have to worry about the quality of the meat you are buying. Japanese design firm To-genkyo have come up with a label that figures out when the meat inside has gone bad.

The trick is that the label consists of ammonia-detecting ink which darkens depending on the level of ammonia present in the enclosed meat.
