Halloween fun is about to land at the National Museum of the U.S. Air Force.

The museum's Family Day will offer themed hands-on activities for all ages from 9 a.m. to 3 p.m. Saturday. Costumes are encouraged, and a limited number of goody bags will be distributed.

Aerospace-related activity stations (all free) include lessons on: vortices, through "shooting" at Halloween targets; density, by "bobbing" for apples; and sound waves, using screaming cups and balloons. Visitors also can play Halloween Skee-Ball and jack-o-lantern cornhole.

Story times for preschool and elementary-age children are scheduled at 11:30 a.m. and 1:15 p.m., followed by a craft. Other activities include an informational scavenger hunt and the chance to build and fly a ring glider between 1:30-3 p.m.
