Come in costume for a non-scary night of Halloween fun. Trick-or-treat through the exhibits, make your own slime, play under black light, create crafts, and more. A host of famous dead scientists will be on hand to amaze you with science tricks that look like magic. This event is skele-tons of fun for the whole family! Sponsored in part by: UTC Aerospace Systems and Rock Road Companies, Inc. $3 members; $9 public. No advance registration needed.
