What is this thing?... and the sugar trail

Some friends invited us over for dinner tonight. Just as we were leaving, our oldest child noted an interesting contraption on our friend's countertop. It had a lid which had been cut from a can dangling from its magnet.
Our oldest child was fascinated and asked - "what is this?" We replied that it was a can opener.
We never realized that she has never seen an electric can opener before as we just use the manual ones. She didn't believe us when we told her and even tried to demonstrate.

On another note, my husband went to the local Costco yesterday to pick up some groceries. I added several food storage items to the list, one of which was sugar.
He picked up a 25# bag of sugar and proceeded to continue to shop. After he'd woven up and down several aisles and across the store, an assistant manager of the store contacted him to let him know that his sugar had a sizeable leak. Apparently he'd left a sugar trail throughout the entire store. The manager's response was that at least he'd been easy to find due to his sweet trail!
