Ahh. What's the favorite day of the week?! Sunday! Because there was an absence of NFL mania on this Sunday, by father suggested that I wash the cars. Ahh, what a good idea because there's no better way to spend a relaxing Sunday than scrubbing hubcaps with a toothbrush. I was washing the car when suddenly, I realized that as I sprayed the car with water, windshield would be covered with a layer of water that did not trickle downwards. That's when that good old physics epiphany came in. BAM! From the heaven fell RAINex DOC!. He trusted a bottle into my hands and shouted (in the classic superhero voice) "Use this on the your windshield, it's like an invisible windshield wiper. Buffing and polishing, I finished off my car was with Rainex. But the true test came that night, when I was driving to the Iolani Basketball game, my car was sprayed by an ignorant sprinkler. Sure enough, as I continued to drive, the water beaded off the windshield and went away like magic! But why?! RAINex DOC!, simply replied it was due to a decrease in friction. Before, all of the dirt particles caused the friction coefficient to increase, cause the water to have a more resistance force against the forces of gravity. When RAINex is applied, the oil mixture makes the windshield covered with a slippery substance that reduces the coefficient of friction, allowing the water to slide off as you continue to drive. AHA! Thanks RAINex DOC! for preventing a future car crash in a rain storm. Lesson of the week: Always have football on Sundays to avoid car washing chores.
