Four runners helped man a stall at the Maidenhead Waterways Fun Day. Avid engineers had the opportunity to learn about how locks work using a miniature toy canal with gates and a pump. Successful participants managed to navigate the little waterway and avoid sinking their boats. Fun was had by all, adults and children alike although there was plenty of splashing and failed attempts. https://m.youtube.com/watch?v=X82PrzRXC70
