Our craft kit lets children create fast-flying gliders—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 planes. Children just use the precut pieces to build a plane…customize it with craft materials (not included)…and put it into action! Then kids test and fine-tune their creation—until they have a plane that soars! You get 40 straws, 30 wings, 30 plastic weights, 50 rubber bands & a guide. The large wings measure 10".
