Update:: Jen sez, "This link is to a video of the 1999 early prototype of the Lids Off Black&Decker jar opener you posted today . I worked on this for my senior project in Mechanical Engineering at Yale University and won the BF Goodrich Collegiate Inventors prize for it. It was picked up by a group that looks for opportunities for products for the disabled and they pushed B&D to make it. Here's the story of the case study."
