Our craft kit lets children create wind-powered sailboats—for a fun-filled introduction to early STEAM concepts! Ideal for integrating STEM with arts & crafts, the kit includes enough materials for kids to engineer 10 real-working boats. Children just use the precut pieces to build a boat…customize it with craft materials (not included)…and put it into action! Then kids test and fine-tune their creation—until they have a boat that sails! You get 10 foam hulls, 60 sails, 40 dowels, 30 foam blocks and a guide. The boat hulls measure 6".
