Host Mo Rocca shows us the device forcing scofflaws to pay parking tickets by covering their windshields; closing a wound with a zip, not a stitch; bike navigation showing riders the way; and, carpets took a beating until the vacuum cleaner was invented.

Mo Rocca shows us grown-up building blocks; the mechanical shoe for those who can't bend over; the breathing pillow to snuggle you to sleep; and, keeping track of historic innovations.
