It's no secret that as a modern society, we take many of our luxuries for granted. We don't think twice before picking up the phone, turning on the TV, or powering up our wireless laptop that allows us to surf the Internet from any location we wish. That's why we we found the following reference question so refreshing!
A patron recently asked us if we could provide her with an explanation as to how car washes work. She didn't need the information for a school project or a research paper; she simply found herself marveling at the complex automation involved in the process of the car wash and was driven to find an answer simply for the sake of learning!
Fortunately, we were able to scrounge up a pretty comprehensive overview from a handy site called How Stuff Works, a resource that explains the science behind hundreds of subjects, from car engines to CD drives to even marriage (yes, seriously!). The overview explains different types of car washes, the science behind the automation of the system, and the step-by-step process (drive in, soap up, scrub, blast, and rinse). It was exactly what our patron was looking for!
