Rockford Register Star: Thanks to the application of some elementary physics, Mark Overmyer of Oregon, Illinois, enabled his daughter Laura (shown here) to triumph in the speed event of last week’s 73rd All-American Soap Box Derby in Akron, Ohio. For the past three years, Overmyer has been perfecting two soapbox innovations: a polyurethane and rubber compound for the wheels and prism glasses, which eliminate the need for the driver to poke her head up in a drag-inducing way to see where she’s going.
