The ZOOMIE BOARD was conceived by a 12 year old female, as her science fair/invention project. It won first place (it was not motorized at the time). It is still technically a 'work in progress' design, as we are still testing various motors on it. It attracts attention whenever she rides it. A detailed information packet is available at the website.
