What families say
Families with a wide age range (reviewers mention kids through adults) report a genuinely hands-on, educational visit, with knowledgeable guides who patiently answer questions and walk you through the campus. Admission and tours are free, but it's a bit of a drive for many and appointments/call-ahead booking is recommended—one family noted they didn't have enough time to see all the exhibits, so plan for a solid chunk of your day. The gravity and wave-form demonstrations are a standout for making abstract physics concepts click for kids.
