Having watched both my boys skip many a stones over at Russell E. Emmenegger Nature Park in the Meramec River, this article gave me some insight into as to what is actually happening when they do that.
The article is entitled “The science of skipping stones on water: Conventional wisdom favors flat rocks, but Splash Lab researchers in Utah get interesting results with squishy spheres” by Michael Graham Richard over at the Mother Nature Network.
Unfortunately the rivers quite high these days, so I don’t know when we’ll get back there but hopefully it will be soon. Sometimes however, they just like to throw really big ones and watch them splash. Oh well!
