Windshield wipers, Gods miracle

The fi­rst windshield wipers were operated manually by moving a lever inside the car back an­d forth. Today, most of us take our electric windshield wipers for granted. The windshield wipers faithfully keep the window clear, moving back and forth across the windshield countless times as they sweep the water away. On their highest speed, they move impressively fast, sometimes shaking the car from side to side. What kind of a mechanism can move the wiper arms so effectively and so reliably? Windshield wipers are found on car windshields, some car headlights, airplanes and even on the space shuttle. Amazing little hands they are. Seriously I never thought that windshield wipers would be of such great value. Wiper blades are like squeegees. The arms of the wiper drag a thin rubber strip across the windshield to clear away the water. When the blade is new, the rubber is clean and has no nicks or cracks. It wipes the water away without leaving streaks. When the wiper blades age, nicks or cracks form, road grime builds up on the edge and it doesn’t make as tight a seal against the window, so it leaves streaks. Sometimes you can get a little extra life out of your wiper blade by wiping the edge with a cloth soaked in window cleaner until no more dirt comes off the blade. Now we have the rain sensing wipers, this helps you measure how fast the wipers should wipe or not. The windshield wiper is important for the safety of the occupants of the vehicle, although it’s one of those parts that is easy to ignore until it’s no longer working. You really can’t afford not to have it working properly. Check the wiper blades always and make sure it is clean and not old and cracked.
