Original, buildable engineering toy & fun science-packed videos alongside each toy. The perfect gift for girls and boys. Every month a Build Box arrives with the most awesome build-it-yourself STEM toy kits and an exclusive video from Mark Rober! When shown the toys and videos, 9 out of 10 of our kid testers freaked out – the 10th was too busy playing with the toy to answer our survey! Each Build Box is centered on a different engineering concept (or superpower), and features a toy that uses that superpower for kids to build, learn, and play with. Each box includes project components for the build-it-yourself toy, a booklet with picture-based instructions, STEM concept explanations, activities and challenges that take the toy to the next level, and a gear badge that celebrates the engineering superpower they just learned about.
