Nature’s Weather Sensor: A Cricket

Let's travel back to a day and age before cell phones.  I say this because most people now a days use them to tell time.  I cannot remember the last time I actually WORE a watch. I just look at the cell.  What is that circular object there you ask?  A clock?  Who needs them anymore, right?  Well if you have one of these and a cricket, yes a cricket, you could figure out what the temperature was.  Did you know that?

Yes, you could use the stopwatch on your cell. I wonder how long it will take for people to not even know what a thermometer is anymore! If you wanted to know the temp and you have a cell, you could probably check it that way too. However, pretend for a minute you didn't have any of those luxuries... if you found a cricket, and you counted his chirps over time, you could tell the temp.  Crazy?
