Join the Science Mill on October 19 for the battiest, bazaar-iest day of learning and fun. Find out why bats are one of our area’s most beneficial native mammals! Southern Wildlife Rehab will have their Bat Cave full of unique exhibits--like bat guano, skeletons and more--and two special presentations with live bats. Special hands-on activities include navigating like a bat with a sonar simulator challenge and much more. Visitors who dress up in their Halloween costumes will receive free Excavation Kits from the museum’s Science Store.
