Herbert's great-granddaughter, Erin Sellner Ward, currently oversees the manufacturing company he formed following the success of the Tilt-A-Whirl. The Sellner Manufacturing Co. produces, on average, 50 rides a year, including other spinning rides, kid-powered mine cars, track rides, and swing rides, for amusement parks around the country. Each Tilt-A-Whirl takes six weeks to construct and costs $375,000. A perfect addition to that water garden in the backyard, next to the cotton candy machine.
