Today is "National Puzzle and Game Day." It celebrates famous games and puzzles and their inventors. In an effort to be part of this esteemed group, today we'll solve a two-part puzzle that plagues all handymen and homeowners. Part 1: When working with tiny screws, nails and small parts, how can you keep from dropping and losing them? Part 2: What can one do with all those flexible rubber magnetic ads for the refrigerator (from pizza parlors, realtors and others in the form of business cards, menus and calendars). Once you've loaded up the fridge, don't toss the extras; put them aside, and the next time you're working with small parts, use them to keep little items from rolling away. Here's another tip: the more magnets you put together, the greater the holding power. Useless advertising? Not at all. Try our tip, and see how their message sticks. And that's the On The House tip for today.
