Hot and Cold

It's Fall, so it's getting a little chilly. But, what if you couldn't feel temperature? What if you were born without the ability to distinguish between ice and water? Between a popsicle and cheese sauce? Between sheet metal and your own face? That would be terrible. You would need this thermometer to tell you that it was Fall. Otherwise, you wouldn't know it was Fall... wait for it... at all!
