Was using an electric can opener (from Bed Bath & Beyond) last night, and this question occured to me:
What actually holds the opened can in place?! The way my can opener works, the blade cuts the can from the top, and when done, it seems like the body of the can should drop and spill to the floor. But it remains suspended, and am wondering what exactly is holding it in place? I've never had spillage and wondering what makes the mechanism work so well, every time?!
