Richard, a chemical and environmental engineer from Michigan, picked up a bucket and sniffed at the contents. He was at the Drywash store, curious about the process used to clean cars without water.
"It's the science of dust," he said, explaining how the natural oils from Brazil work in extracting the dirt off cars. He explained charge density, polarisation and the the principle of surfactants in soaps. Using his hand, he drew an elaborate mental picture of electrons spaced out on a surface. Further gestures demonstrated how an organic oil with a high charge density attracts the dust off a surface.
I wish high school particle physics was explained with such clarity and passion!
I'm pushing for high-school students to apprentice at businesses like Drywash - to put their science skills to practical use. Parents would benefit from teenage boys going offline, putting their games and toys away to do something physically demanding - like learning how to clean cars. The gradual demise of metrosexuality lends momentum to the next wave - men who are comfortable getting dirty.
