ripe and ready

A University of Arizona professor may have just eliminated a significant number of phone calls home to Mom asking for grocery advice.  Mark Riley has invented a sticker that will tell consumers whether the piece of fruit they are holding is considered ripe.  The sticker detects the level of ethylene gas the fruit is producing and shifts the sticker color from white to blue.  The riper the fruit, the darker the blue.  It is an interesting theory and makes for an inexpensive product that should be in your local grocery store in about two years.  Not really sure if it would work for tomatoes since they are ripened using ethylene but most other fruits are probably up for grabs.  It may be that the days of squeezing melons are over…….or is it squeezing peaches?  I’m calling Mom.
