New way to get ice off the drive way

Typical winter in Kansas, it rained then froze ice all over the road ways. As I am coming into the house, I notice by the door my 10lb sledge hammer. Before I could ask my 18yr son if he knew why it was left out there, he reports "hey dad the sledge hammer works real good on getting the ice off the driveway." So at least I will not be wondering how tf did these chips get into my driveway last winter.
