This model showcases another type of floating offshore wind foundation: the spar buoy. The set includes a spar buoy with a connection ring and three attachment points, along with a wind turbine. Children can discover how the tall, slender buoy floats upright in the water and stays stable thanks to heavy ballast. By using saturated sand as ballast, kids can experiment with how engineers keep the spar anchored and balanced, even in challenging sea conditions. This hands-on activity introduces them to one of the most widely used floating wind designs and the engineering principles behind its stability.
