Your kids have boundless energy and huge imaginations. This weekend, take advantage of both with a trip to Kidspace Children’s Museum in Pasadena. Filled with educational playgrounds and interactive exhibits, it’s just the place to let the little ones explore the big world they live in. Their eyes will widen as they crawl through the “underground” ant colony. Their smiles will shine as they reach the top of the majestic Raindrop Climber — you’d think they’d just climbed Everest. Watch them giggle as they measure their height against the giant wall of pencils at the Bug Inn, where they see the world from a bug’s point of view. Towels and bathing suits are a must–after seeing your kids make waves at Splash Dance Fountain, you might want to join in. At Kidspace, learning comes with a side dish of fun. The Ball Bounce — where kids use gravitational acceleration to transfer energy — would make Isaac Newton envious. The Flutterby Art Center—where kids create masterpieces from natural materials—would impress Picasso. Before long, you’ll need a break, so take a load off at the Spot Gourmet Café, where the kids can regale you with their newly-discovered secrets of the universe.
