The Polaroid camera was introduced on this date in 1946. Today, years later, instant pictures are still a good idea, especially when something breaks like an appliance that's big, heavy and bulky or something attached that can't be removed. These appliances can't be brought to the hardware store or home center to indicate what you need repaired or replaced. Instead of making sketches and using hand gestures and less-than-descriptive terms like "whatchamacallit" or "thingamabob," use a Polaroid camera to capture your pesky problem on film. You'll find you're probably not the first person to have had this problem, and your friendly hardware guy will know just what you need and what to do. With a Polaroid, you can skip guessing and fussing and sketching and cussing. And that's the On The House tip for today.
