This is the construction set of glowing “joists” that allow young builders to re-create 30 of the world’s most famous landmarks. Inspired by National Geographic’s devotion to historical treasures and heritage archaeology sites, this kit’s 244 sturdy plastic pieces reconstruct sites such as the Roman Colosseum, Sphinx, Elizabeth Tower (home to Big Ben), or the Lincoln Memorial on a board with built-in electronics that illuminate 32 colored laser pegs that cast each edifice in a rainbow of light. Requires three AA batteries. Ages 5 and up. 12" H x 8" W x 4" D. (3 lbs.)
