Sadly, Christmas is over and I have to wait another 54 weeks before being able to enjoy my favorite holiday of the year again. I am going to take a wild guess, however, that at least one of your Christmas presents is made with some rubber. Whether that gift is a bicycle, tennis shoes, balls, or any range of gifts, rubber is everywhere today! Yet, did you realize a little more than one-hundred fifty years ago, materials made out of rubber were considered worthless. And, those that did exist were of limited use because they melted immediately upon getting hot!
