More Info: Do you wanna build a snowman? Kids will have fun at several themed activity stations throughout the museum, including a wintry princess station, a snowflake station, and a Sven station. The museum's wandering S.T.E.A.M. Cart will offer Freezing Cold Science Shows several times each day. And, of course, there will be character appearances all weekend! Also, keep your eyes peeled for a fun online activity related to this weekend-long event. Timed tickets are available and you're encouraged to purchase your admission tickets ahead of time.
