If you've ever longed to sleep in the shadow of a 747-and really, who hasn't?-check out MSI's Snoozeum, a rare opportunity to catch your zzz's at one of Chicago's premier science spots.
Families with kids 6-12 can explore the museum after everyone else has gone home, complete with a scavenger hunt through the exhibits and some science activities. We don't think any exhibits will come to life, but we're guessing that coal mine gets pretty creepy after dark.
Sign up soon; this event fills up early. 6 p.m. June 22-8:30 a.m. June 23. $45, includes admission, activities, snack and breakfast. Museum of Science & Industry, 5700 S. Lake Shore Drive, Chicago. (773) 684-1414, msichicago.org.
