Piece together 48 sturdy jumbo cardboard jigsaw pieces for an experience that's out of this world. Assemble the detailed and colorful space scene in a brightly lit room. When the three-foot by two-foot puzzle is complete, turn out the lights and watch as hidden pictures and details appear in glow-in-the-dark ink. The puzzle must first be exposed to bright light to activate the glow-in-the-dark feature. Playing with puzzles is a great way for kids three and older to explore the fascinating world of outer space while developing their cognitive, physical, and emotional skills. When children work on floor puzzles, they are fine-tuning their gross motor skills, improving their hand-eye coordination, strengthening their problem-solving skills, and beginning to develop logic and critical thinking processes. This high-quality Melissa and Doug puzzle makes an exceptional gift for preschoolers and school-aged kids for hands-on, screen-free play.
