On my walk to work this morning, I noticed the pattern in the deposits on these fountains in Lakeshore East Park, by my apartment. The water deposits minerals in uniform isosceles triangles. Something about the surface tension of the water droplets, and the force behind the water as it is ejected from the spigot - planned, not random. Science. Weird/awesome, no?
Almost makes me wish I had been a physics major, instead of good ol' advertising. But, not quite.
